Dynamic Column Sorting After Merge Join

Feb 25, 2008



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!

Dynamic Join Based On Column Value??

May 4, 2007

Hi,

I have three tables.

The "Master table has a recordid, a masterID, a "IsSubField" and other stuff.



I need to do a join to a second table based on the MasterID...



However for each record, if the "IsSubField" has a True value then it has to use table A to JOIN to, where as if it's False, then it uses table B.



Make sense?



Anyone got any pointers?



Thanks in advance

Not sure if this is ever going to be possible, but I'm trying to do a dynamic join on EXECUTE, but the execution string has to come from a table column.... i.e

select * from (select table1.theSql,table1.userid from table1 ) as a

inner join (execute a.thesql) as b

Integration Services :: Pass Single Column Of Values From Successful Merge Join To EXECUTE Statement

May 7, 2015

How do I pass a single column of values from a successful merge join to an EXECUTE SQL statement so it can be used with an "IN" criteria of the WHERE clause?  Here's an example of my update statement with two random key values:

UPDATE dbo.MyTable SET MyStatus = 1 WHERE MyPK IN ("XYZ123", "DEF890")

Is this even possible in SSIS, or am I better off using a loop and running the update EXECUTE SQL Statement for each individual key value, as in the following example?

UPDATE dbo.MyTable SET MyStatus = 1 WHERE MyPK = "XYZ123"
UPDATE dbo.MyTable SET MyStatus = 1 WHERE MyPK = "DEF890"

Merge Replication W/ Dynamic Row Filter - Not 'dynamic' After First Initial Sync?

May 2, 2007

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?

'Left Outer Merge Join' Failing To Join Valid Row

Scenario:

OLEDB source 1
SELECT ...

4-400-1000123

4-400-1000125
...

All other rows are joining as expected.
Why is it failing for this one row?

Merge Join (Full Outer Join) Never Finishes.

Jun 5, 2006

I have a merge join (full outer join) task in a data flow. The left input comes from a flat file source and then a script transformation which does some custom grouping. The right input comes from an oledb source. The script transformation output is asynchronous (SynchronousInputID=0). The left input has many more rows (200,000+) than the right input (2,500). I run it from VS 2005 by right-click/execute on the data flow task. The merge join remains yellow and the task never finishes. I do see a row count above the flat file destination that reaches a certain number and seems to get stuck there. When I test with a smaller file on the left it works OK. Any suggestions?

How To Join 2 Datasets Without Sorting

May 12, 2006

Hi,

In one of my packages, I have join data from 2 data sets. The problem is 'Join' requires both dataset to be sorted and I can't sort one dataset without 'sort' transformation. The real problem is since I have to sort 65million records, the sort operation sucks always. The other option is using 'Lookup', but since I have to do 'Range Lookup', it is taking hours and hours to process less # of records.

My question is, is there any other way, I can do join of 2 datasets without sorting?

Super Join - Is Merge Join The Answer?

Nov 7, 2006

Is there a way to do a super-table join ie two table join with no matching criteria? I am pulling in a sheet from XL and joining to a table in SQLServer. The join should read something like €œfor every row in the sheet I need that row and a code from a table. 100 rows in the sheet merged with 10 codes from the table = 1000 result rows.

This is the simple sql (no join on the tables):

select 1.code, 2.rowdetail
from tblcodes 1, tblelements 2

But how to do this in SSIS?

Thanks - Ken

How Can I Apply Dynamic Sorting For Columns In Matrix Reports

Apr 30, 2008

Hi,

We have a matrix report which displays columns in a default sorting order. This report columns vary dynamically depending on the user input.

e.g. If user wants to see the report for column Alfa, Beta , Gama then a report will be genarted with column Alfa, Beta , Gama sorted in alphabetical order.






Site
%Risk
Alfa
Beta
Gama

X
2
1
2
3

Y
10
4
5
6
However the users want the Columns to be sorted in the order which they provide the inputs e.g. if the user entered Gama, Alfa, Beta the report should display the columns in the same order instead of applying the default sorting order.






Site
%Risk
Gama
Alfa
Beta

X
2
3
1
2

Y
10
6
4
5

Any thoughts on ways to achieve this in SSRS matrix report would really help.

Cheers,
Viv

Importing Excel Sheet Which Have Dynamic Column Name And Dynamic Number Of Columns

Aug 25, 2007

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.

Merge Replication And Dynamic Filters

Jan 5, 2005

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

Merge Replication With Dynamic Filter

Jun 14, 2006

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.

When we click on "Next Run Date," the list is reordered, butrandomly. Each time we click it we get a different order but neverascending or descending.

I have a simple join query like this
select a.id from tbl_a a, tbl_b b where a.id = b.id and I want insert the result to my temp table.
the query results is 1500 rows.
but when I use merge join in SSIS, it only inserts to my temp table 4 rows.
I use inner join and I already set the IsSorted to true and specify the sort position for the columns in both source tables
In tbl_a, there are one million rows, in tbl_b, there are 2000 rows.
I don't know why the merge join cannot work out my task.Is there other way that I can just run this simple join query in SSIS to copy the data?

Merge Replication Using A Guid As A Dynamic Filter

Aug 12, 2006

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

Alex
