Merge Dynamic Filter Problem
Feb 2, 2007
Hi!
I'm a merge newbie and have a couple of questions. I'm about to setup a merge replication with Sql Server 2005 and Sql Server CE as a subscriber. Situation is like this, we have 10 service technicians using pda.
I want to each pda user have their own data. What I understand I need to use dynamic filter and SUSER_NAME()?? Do I need to create a "translation" table to map my system's UserId against SUSER_NAME? How have you solved this problem?

If anyone could confirm...
SQL Server 2000 SP4 to multiple SQL Server 2005 Mobile Edition on PDAs. My DB on SQL2k is published with a single dynamic row filter using host_name() on my 'parent' table and also join filters from parent to child tables. The row filter uses joins to other tables elsewhere that are not published to evaluate what data is allowed through the filter.
E.g. Published parent table that contains suppliers names, etc. while child table is suppliers' products. The filter queries host_name(s) linked to suppliers in unpublished table elsewhere.
First initial sync with snapshot is correct and as I expected - PDA receives only the data from parent (and thus child tables) that matches the row filter for the host_name provided.
However - in my scenario host_name <--> suppliers may later be updated E.g. more suppliers assigned to a PDA for use or vice versa. But when I merge the mobile DB, the new data is not downloaded? Tried re-running snapshot, etc., no change.
Question: I thought the filters would remain dynamic and be applied on each sync?
I run a 'harmless' update on parent table using TSQL e.g. "update table set 'X' = 'X'" and re-sync. Now the new parent records are downloaded - but the child records are not!
Question: I wonder why if parent records are supplied, why not child records?
If I delete existing DB and sync new, I get the updated snapshot and all is well - until more data added back at server...
Any help would be greatly appreciated. Is it possible (or not) to have dynamic filters run during second or subsequent merge?

Brand new to SQL Server 2005 and replication, I was able to use online books info to get a replication topology set up (using wizards) and successfully replicate an article (a single table) to a SQL Server Express database.
I then cleared the subscription table and added a simple dynamic filter (colx = SUSER_SNAME()), which I can't get to work. Based on what I read, I'm thinking that SUSER_SNAME() is not returning the proper value because the merge agent is set to connect to the publisher and distributor by 'impersonating the process account'. This is on the subscription merge agent security form. However, 'using a SQL Server login' is greyed out and nothing I tried will enable it, including setting up logins and SQL user ids on the publisher and playing with entries on the publication properties data partitions page, etc.
I think that I have discovered only some of the pieces that I need and not enough details to find the rest and put them together. Any info on what to have set up where would be appreciated. Any suggestions for 'step by step' information that would help in addition to SQL Server 2005 Books Online would be great.
Thanks in advance.

Hi ...
I am working on a project where the server version of application has vouchers from different entities. I have created a publication manually. My next step was to create a client subscription using rmo and to execute a pull. This part works fine. Code samples from http://msdn2.microsoft.com/en-us/library/ms147314.aspx
My next step would be to implement dynamic filtering using the guid of the entity as a parameter.
I dont want to use suser_sname() or host_name() as I want to use a fixed login for the replication for all users, and a client could have several host dbs (sql express, sql mobile)
My goal would be to pass a guid-value to the HostName Property of the MergePullSubscription class and convert it to an uniquidentifier and use it as a filter as I have not found any other way to pass a guid as a filter.
RMO-Code:
subscription.HostName = "4bb0e468-c68a-4253-ba82-f71c3a6e302d"
Filter:
SELECT <published_columns> FROM [dbo].[voucher] WHERE [entity_ID] = dbo.fx_ConvertHostToEntity()
Function:
create function fx_ConvertHostToEntity()
returns uniqueidentifier
as
Begin
declare @host nvarchar(50)
set @host = host_name()
declare @entity uniqueidentifier
set @entity = cast( @host as uniqueidentifier)
return @entity
End
When trying to set the filter sql server complains that a character string cannot be casted to a uniqueidentifier - so i can not set this filter. Is there a way to pass a parameter other then the username or the hostname as a filter?
SELECT <published_columns> FROM [dbo].[voucher] WHERE [entity_ID] =@entity, where @entity is a guid
Thanks for your support

I am currently running sql 2000 with 2 way merge replication... I have a problem of I need to delete about 3 million rows from a table that is constantly being accessed buy an e-commerce site. I have thought about setting up a filter to only replicate new or altered rows beyond a a certain indexed number... then delete from both sites the unneeded rows... this should work.. but can I delete the filter after I am done??
If this is not an option, any other suggestions?? I cannot take either site offline and I cannot do anything that will take more than a few seconds to replicate... by deleting these rows. my table size will be reduced by almost 8GB...
thanks

Hi,
I have a merge (SQL 2005 Standard -> Express) topolgoy which is having problems
The main problem is that the join filters don't seem to work for one area and I am hoping someone can help me with some troubleshooting advice
There are 140+ tables in the topology but the ones causing particular pain are a parent child relationship where the child is actually a bridge/linking table to another table.
Therefore although it is a parent child in the replication filters it is the reverse. i.e. the child has the paramterised filter on it and the parent is one level down joined by it's id. There are other tables joined to this parent table but it stays at three levels deep. The @join_unique_key therefore is set to 0 as is the partition options for the parent /child relationship.
However, when we synchronise we have a problem. The rows get inserted in to the database in RI order but only the child records are replicated down to the subscriber.
The child table with the parameterised filter has 13 articles joined to it in total and one of the other branches of join filters go down as deep as four levels. Most though do not.
Does anyone have any suggestions as to why this might be happening? Any help would be greatly appreciated.
Cheers, James
P.S. I should add this problem only occurs when the edits are made at the publisher. If new records are added at the subscriber everything is fine.

Here is what I am trying to do in SSRS 2005.
Setting up filters based on parameters with an expression like this:
=Iif(Parameters!Company.Value = "", "", Fields!company.Value)
In the wizard we are creating, we are also letting the user choose the operator for each parameter that they choose. My question is how can I change the filter dynamically based on the user choosing a specific parameter and also choosing an operator to associate with that parameter??
Example 1: User 1 chooses the Company parameter to filter their report, and they choose the parameter to equal (=) a specific value. So the filter expression would be like the one previously mentioned and the operator would be an equal sign.
Example 2: User 2 chooses the Company parameter to filter their report, and they choose the parameter to be LIKE a specific value. So the filter expression would be like the one previously mentioned and the operator would be LIKE.
How can I do this?
Thanks in advance for your help.

Hi!
Is there any way to use datetime value as dynamic filter in the Merge Replication?
(Yeah, I use HOST_NAME in order to pass datetime value)
I used all possible approaches, but or I got the error
Conversion failed when converting datetime from character string. (Microsoft SQL Server, Error: 241)
or I got 0 rows on the subscriber after synchronization.
Any ideas how it can be solved?
Thanks

We have a table in an SQL Server 2012 database that stores tree-like structures. Simplified for the purpose of my question, it has the following format:
Id int identity,
ParentId int,
GroupId int
Each record of the table represents an object identified by Id. An object may or may not have a parent in the same table, such that object.ParentId = parentObject.Id. A root object has ParentId = NULL. There are multiple root objects, so the table in fact stores multiple trees. What’s important is that the tree depth is not fixed, i.e. theoretically there can be any number of ancestor generations for an object. GroupId is a property of a root object; in theory none of the children of a root object has to have GroupId <> NULL; it can be assumed that any child has the same GroupId value as its root object.
A sample table having two roots (one grandparent and one parent), one non-root parent/child and 4 child roots:
Id ParentId GroupId
----------------------------------------------------------
1 NULL 200 root grandparent
2 1 NULL non-root parent/child
3 2 NULL child
4 2 NULL child
5 NULL 300 root parent
6 5 NULL child
7 5 NULL child
The table is not normalised, i.e. there’s no separate {root_object : group} table. However I don’t think normalising the table would solve the problem.
Now the problem. We need to set up merge replication from the table above (Master table) to the table of the same format in another DB. We need to replicate only those rows of the Master table that have a certain fixed GroupId value, e.g. 200 in the example above. If we ensure that GroupId in all descendant objects of a root object has the same value in the table as the root object itself that would be trivial. The table would look like this:
Id ParentId GroupId
----------------------------------------------------------
1 NULL 200 root grandparent
2 1 200 non-root parent/child
3 2 200 child
4 2 200 child
5 NULL 300 root parent
6 5 300 child
7 5 300 child
And the filter would look like this:
WHERE GroupId = 200
However out of performance considerations, we would like to avoid if possible filling GroupId for the descendant objects, because as it must be clear from the above, GroupId for a descendant object is quite easily deducible via a stored procedure or UDF (just need to go up the tree until ParentId = NULL). The problem is, I don’t know how to achieve this in a merge replication filter: it would only allow WHERE conditions and joins. I’ve have not had much luck with joins for merge replication in general, but here we have more complex algorithm, because the number of tree levels can be different for every object. And merge replication would not allow using UDF…

I have a requirement to add the ability to filter a report by partial last name, at the report level (i.e. not at the database server). In case someone else needs to work out how to do this, here is what I did.
Add a Parameter to the report. In my case it is named LastName, is non-queried, allows Null or Blank, and has a default of null.
Add a filter to the dataset that contains the field to be searched. Set its Expression to:
=IIF(Parameters!LastName.Value = System.DBNull.Value OR Parameters!LastName.Value = "",
Fields!LastName.Value, Nothing) ,
its operator to "="
and its value to =IIF(Parameters!LastName.Value = Nothing OR Parameters!LastName.Value = "", Nothing, Parameters!LastName.Value & "*")
voila!

I have several SQL Mobile devices (WM5) syncronizing with a SQL 2005 database through merge replication. We are using the HOST_NAME parameter to filter several tables. A few of these filters use a sub-query to filter the data because of the complexity of the filter (need to do more than join to one table). The subquery will use the HOST_NAME parameter. For example, I want to get a list of all users in the current user's company I need to use host_name to get the current user, find their company ID, then filter the user table on that company ID.
Everything works fine until a user is removed from the table. In that case, the delete statement is not replicated to the device until they reinitialize the mobile database.
Thanks for the help!!

I have a table:
declare tableName table
(
uniqueid int identity(1,1),
id int,
starttime datetime2(0),
endtime datetime2(0),
parameter int
)
A stored procedure has new set of values for a given id. Sometimes the startime and endtime are the same, in which case I update the value of parameter. Sometimes I add a new time range (insert statement), and sometimes I delete a time range (delete statement).
I had a question on merge, with insert, delete and update and I got that resolved. However I have a different question regarding performance of the merge statement.
If my target table has hundreds of millions of records and I want to delete/update/insert a handful of records, will SQL server scan the entire target table? I can't have:
merge ( select * from tableName where id = 10 ) as target
using ...
and I can't have:
merge tableName as target
using [my query] as source on
source.id = target.id and
source.starttime = target.startime and
source.endtime = target.endtime
where target.id = 10
...
This means I cannot filter the set of rows in the target table to a handful of records where id = 10.

Hi,
I would like to setup a merge replication from a main database (publisher), to around 100 client databases (subscribers), that contain only subset information for each distinct client: each client has then its own database to view and modify its own data (Filtered on rows and columns). The client databases will initially be hosted on the same SQL server Instance.
I don't want to setup manually 100 publications with static filters, and more may come in the future: a pain to setup and maintain because I have to configure the tables, the columns and the row filters (and joins) each time.
I would like then to setup one publication with a dynamic filter, to filter in a way or another on a specific client. Creating subscribers becomes then a piece of cake. The dynamic filter would apply based on a property specific to the client, but... HOW?
Filtering on HOST_NAME() will not work because several subscribers are on the same server.
Filtering on SUSER_SNAME() will not work because merge agent will always use the same user name for connecting to the publisher (using push subcription, all merge agents are on the same server), and I have not find out how it can be configured by merge agent: even if the merge agent jobs have different owner, it is always the SQL Server Agent login that is used to connect to the publisher (I am using windows authentication).
I was thinking about using DB_NAME(), and have specific db name for each client DB, but DB_NAME() provides the name of the publisher DB, not the subscriber DB. etc ...
What could I use in this case to dynamically filter on client data without having to fall into heavy replication administration and setup.
Thanks for your help,
Best regards

Hello,
I have data coming in from two sources, one being SQL and the other being Oracle. The end result needs to be a CSV file with the columns in a specific order. I have a Data Flow task setup that takes both sources and does a Merge Join on them. I can add a Sort Transformation and manually set the sorting of all 156 columns that end up going to a CSV file destination. However, I have a table setup that holds the names of the 156 columns and the order that the CSV file expects them to be in. I would much rather do this step dynamically as the column names and order may change in the future. Anyone who has used the Sort Transformation for a large number of columns knows how tedious it can be and how adding a column in the middle will cause you to change the sort # for each of the columns that come after it.
So I added a Script Component between the Merge Join and the Flat File Destination hoping that I could alter the order of the columns there. However I added the following code and found that the SortKeyPosition is ReadOnly.
Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)
Dim column As IDTSInputColumn90
For Each column In Me.ComponentMetaData.InputCollection(0).InputColumnCollection
column.SortKeyPosition = 1
Next
End Sub
I was hoping to add some code to get the sort index from my table for each of the columns and set it to the SortKeyPosition. Has anyone out there done this before or seen an example that might point me in the right direction? I've searched for 2 days without coming up with much.
Thanks!

I am working on to convert my static Store procedure to Dynamic.
I have created a Store procedure with Merge statement which is inserting new record and updating existing record.
This SP I will use in SSIS Insted of Data Flow Task I will run in Execute SQL Task.
Now my biggest problem is I dont know how to convert static code toi dynamic
Below is my Store procedure code.
As you can see my Source Query
I have a filemaster table as shown below which consist of Input filename,Source table ,Destination table and BBX expression.
Input_FilenameSourceTableName DestinationTableName BBxKeyDerExpr
CCTFB ImportBBxCctfb ArchiveBBxCctfb SUBSTRING(Col001,1,6)
CEMXR ImportBBxCemxr ArchiveBBxCemxr SUBSTRING(Col001,1,10)
In my source query I want to change the value of Source table ,Destination table and BBX expression dynamically on the basis of input file.
Purpose of making dynamic is that I have created separate sp for all the input, my clients want to have sungle dynamic sp which will execute on the basis of input file.this input file name I wil get fromm variable which i have created in SSIS Package.
Lets consider @File_name is the variable in package which store the file name
if file name is CCTFB then my query should take the Source table ,Destination table and BBX expression value from file master table.
Like that I have 100 of source query and evry query have diffrent number of columns. How can I change the column number in uodate and insert statement dynamically on run time.
CAST(SUBSTRING(Col001,1,6) + SUBSTRING(Col002,1,10) AS varchar(100)) :-It creates a key for comparing, this value i can take it from filemaster
HASHBYTES('MD5', CAST(CHECKSUM(Col001, Col002,Col003,Col004) AS varchar(max))) -here numberv of column need to be changed .
(SUBSTRING(SOURCE.Col001,1,6) + SUBSTRING(SOURCE.Col002,1,10)) this condition also i can take it from file master.
[Code] ....
I am able to get inserted and updated rowcount, but not able to get the matching records count.

Hello,
Here is my problem:
I use SQL Server 2005. I have approx. 50 tables in my database and 30 of them have a filed named "CompanyID". Example:
create table A (ID int identity, NAME varchar(100), COMPANYID int)create table A (ID int identity, REF_ID int, FIELD1 varchar(100), FIELD2 varchar(100), COMPANYID int)
Also there are nearly 200 stored procedures that read data from these tables. Example:
create procedure ABCasbegin /* some checks and expressions here ... */ select ... from A inner join B on (A.ID = B.REF_ID) where ... /* ... */end;
All my queries in the Stored procedure does not filter the tables by CompanyID, so they process the entire data.
However, now we have a requirement to separate the data for each company. That means that we have to put a filter by CompanyID to each of those 20 tables in each query where the tables appear.
Firstly, I put the CompanyID in the context so now its value is accessible through the context_info() function. Thus I do not need now to pass it as a parameter to the stored procedures.
However, I don't know what is the easiest and fastest way to filter the tables. Example:
I modified the above mentioned procedure in the following way:
create procedure ABCasbegin /* some checks and expressions here ... */
-- gets the CompanyID from the context: DECLARE @CompanyID int; SELECT @CompanyID = CONVERT(float, CONVERT(varchar(128), context_info()))
select ... from A inner join B on (A.ID = B.REF_ID) where ...
and A.COMPANYID = @CompanyID and B.COMPANYID = @CompanyID /* ... */end;
Now I have the desired filter by CompanyID. However, modifying over 200 stored procedures is rather tedious work and I don't think that this is the best approach. Is there any functionality in SQL Server that can provide the possibility to put an automatic filter to the tables.
For example: when I wrote "SELECT * FROM A", the actual statements to be executed would be "SELECT * FROM A WHERE CompanyID = CONVERT(float, CONVERT(varchar(128), context_info()))".
I was looking for something like "INSTEAD OF SELECT" triggers but I didn't manage to find any answer.
I would very grateful is someone suggests a solution for something like "global table filter" (that will help me make an easy refactoring)?
Thanks in advance.
Best regards,
Beroetz

Howdy,
I have a table that has a group. In this group, I want to filter by 2 different expressions, concatenated with an OR. BUT I can't change the "And/Or" column value for the first entry because it is grayed out. The column will automatically change to an OR value if both my expression column fields are the same (which I don€™t want) but if I put any other value in to the expression field of the second row, the "And/Or" field of the first row automatically changes to an AND.
PLEASE! How do I get the And/Or field "ungrayed" so I can change it to what I want?
The 2 filters I and using check the UserID = to the user, and the other is checking a count to get the Top N 1. (So just showing the current user and the top producer)

I have database on SQL Server 2000 set up with a merge publication.This publication is configured with a number of dynamic filters toreduce the amount of data sent to each client. Each client has ananonymous pull subscription. The merge process can be triggered by thewindows sync manager and my application.To improve performance I have created some helper tables to hold themapping between user login and primary keys of selected entities.For the replicated data to be correct the contents of the helper tablesneeds to be up to date.I need to fire off a stored procedure on the publisher beforereplication starts to verify that this data is up to date. I can notsee any documented way of doing this however I have been experimentingwith some unorthodox systems.Firstly has anyone any ideas?I have been considering adding a trigger to some of the tables used bythe Microsoft replication code - yes I know this is very nasty.My problems arise because executing this stored procedure will causesome data to be updated. In updating data we could create a newgeneration in the database. I must therefore run my stored procedurebefore any the Microsoft code makes any generation checks / updates.Anyone done anything similar, Anyone have any better ideas?Any comments would be gratefully received.

Hi,
I'm using merge replication to maintain a backup copy of my main (publisher)MSDE database. A push subscription periodically (1 per minute) updates the backup DB.
It's intended that if the main db goes down then the backup (subscription) db can be configured as a publisher. This must all be performed via scripting.
The initial configuration of the main publisher and subscription is controlled via scripting, which works fine.
The problems occur when I try to configure the subsciber to become a publisher. A script is executed on the subscriber but fails at the point when it's configuring the publisher detail. The error is something like "unable to configure a publication for a database setup as an anonymous subscription".
I'm guessing that there are subscritpion artifacts added to the database which need to be removed before it can be configured as a new publisher.
Please help,
Jez W

Hi Craig/Kamal,
I got your email address from your web cast. I really enjoyed the web cast and found it to be
very informative.
Our company is planning to use SSIS (VS 2005 / SQL Server 2005). I have a quick question
regarding the product. I have looked for the information on the web, but was not able to find
relevant information.
We are getting Source data from two of our client in the form of Excel Sheet. These Excel sheets
Are generated using reporting services. On examining the excel sheet, I found out that the name
Of the columns contain data itself, so the names are not static such as Jan 2007 Sales, Feb 2007 Sales etc etc.
And even the number of columns are not static. It depends upon the range of date selected by the user.
I wanted to know, if there is a way to import Excel sheet using Integration Services by defining the position
Of column, instead of column name and I am not sure if there is a way for me to import excel with dynamic
Number of columns.
Your help in this respect is highly appreciated!
Thanks,
Hi Anthony, I am glad the Web cast was helpful.
Kamal and I have both moved on to other teams in MSFT and I am a little rusty in that area, though in general dynamic numbers of columns in any format is always tricky. I am just assuming its not feasible for you to try and get the source for SSIS a little closer to home, e.g. rather than using Excel output from Reporting Services, use the same/some form of the query/data source that RS is using.
I suggest you post a question on the SSIS forum on MSDN and you should get some good answers.

Hi,
I have a need to display on screen AND email a pdf report to email addresses specified at run time, executing the report with a parameter specified by the user. I have looked into data driven subscriptions, but it seems this is based on scheduling. Unfortunately for the majority of the project I will only have access to SQL 2005 Standard Edition (Production system is Enterprise), so I cannot investigate thoroughly.
So, is this possible using data driven subscriptions? Scenario is:
1. User enters parameter used for query, as well as email addresses.
2. Report is generated and displayed on screen.
3. Report is emailed to addresses specified by user.
Any tips on how to get this working?
Thanks

I have a Stored Procedure for processing a Bill of Material.
One column on the Assembly Table is a Function Name that contains some busniess rules.
OK, now I'm doing a Proof of Concept and I'm stumped.
Huuuuh!
I will ultimately have about 100 of these things. My plan was using Dynamic SQL to go execute the function.
Note: The function just returns a bit.
So; here's what I had in mind ...
if isnull(@FnNameYN,'') <> ''
exec spinb_CheckYN @FnNameYN, @InvLineID, @FnBit = @FnBit output
CREATE PROCEDURE dbo.spinb_CheckYN
@FnNameYN varchar(50),
@InvLineID int,
@FnBit bit output
AS
declare @SQL varchar(8000)
set @SQL = '
if dbo.' + @FnNameYN + ' (' + convert(varchar(31),@InvLineID) + ')) = 1
set @FnBit = 1
else
set @FnBit = 0'
exec (@SQL)
GO
Obviously; @FnBit is not defined in @SQL so that execution will not work.
Server: Msg 137, Level 15, State 1, Line 4
Must declare the variable '@FnBit'.
Server: Msg 137, Level 15, State 1, Line 5
Must declare the variable '@FnBit'.
So; is there a way to get a value out of a Dynamic SQL piece of code and get that value INTO my OUTPUT variable?
My many thanks to anyone who can solve this riddle for me.
Thank You!
Sigh: For now, it looks like I'll have a huge string of "IF" statements for each business rule function, as follows:
Hopefully a better solution comes to light.
------ Vertical Build1 - Std Vanes -----------
if @FnNameYN = 'fnb_YN_B1_14'
BEGIN
if dbo.fnb_YN_B1_14 (convert(varchar(31),@InvLineID) ) = 1
set @FnBit = 1
else
set @FnBit = 0
END
------ Vertical Build1 - Scissor Vanes -----------
if @FnNameYN = 'fnb_YN_B1_15'
BEGIN
if dbo.fnb_YN_B1_15 (convert(varchar(31),@InvLineID) ) = 1
set @FnBit = 1
else
set @FnBit = 0
END

I have a requirment which i have partly accomplished , but could not get through completely
i have a file which comes in a standard format ending with date and seq number ,
suppose , the file name is abc_yyyymmdd_01 , for first copy , if it is copied more then once the sequence number changes to 02 and 03 and keep going on .
then i need to transform those in to new file comma delimited destination file with a name abc_yyyymmdd,txt and others counting file counting record abc_count_yyyymmdd.txt. and move it to a designated folder. and the source file is then moved to archived folder
what i have taken apprach is
script task select source file --------------------> data flow task------------------------------------------> script task to destination file
dataflow task -------------------------> does count and copy in delimited format
what is happening here is i can accomlish a regular source file convert it to delimited destination file --------> and move it to destination folder with script task .
but cannot work the dynamic pick of a source file.
please advise with your comments or solution you have

I am trying to create an ssis package with dynamic csv file as output. and out format contains query output.
sample file name:
Unique identifier + query output + systemdate();
The expression is looking like this.
@[User::FilePath] + @[User::FileName] + ".CSV"
-- user filepath is a variable from ssis package. File name is the output from SQL query. using script task i have assigned the values to @[User::FileName] .
When I debugged the script task the value getting properly but same variable am using for Flafile destination. but its not working.

Hi I am wandering if it is possible to achieve the following:
I am using Reporting Services and Reporting services I got a report with a text parameter.
I would like the user to introduce AA and find the product AA and when he introduces AA* it finds AA, AAD, AAC...
I am doing the following:
Filter([DIM Product].[Product].ALLMEMBERS,
,IIF(INSTR(@Product, "*") > 0
,[DIM Product].[Product].currentmember.name = Replace(@Product, "%", "")
,INSTR([DIM Product].[Product].currentmember.name, @Product)
)
)
The problem ist that the function Replace does not work!
Does someone know how to do it?

What is the syntax for using IN as a filter? in SQL it would be IN( 'A', 'B', 'C') but this does not work in Reporting services.

I have created a dynamic SQL program that returns a range of columns (1 -12) based on the date range the user may select. Each dynamic column is month based, however, the date range may overlap from one year to another. Thus, the beginning month for one selection may be October 2005, while another may have the beginning month of January 2007.
Basically, the dynamic SQL is a derived Pivot table. The problem that I need to resolve is how do I now use this dynamic result set in a Report. Please keep in mind that the name of the columns change based on the date range select.
I have come to understand that a dynamic anything is a moving target!
Please advise.

In a SQLDataSource, the following line throws an error as an undefined function. FilterExpression='left$(lname,1) = "D"'
Isn't this a standard VB function and why does it produce an error. How do I fix?
Thanks
