Form Variables Not Persisting In SSRS

Feb 6, 2008



Hello All,

I am a super newbie here.

I have a Form that submits to a new window with a reportViewer control in it.

I am using the request variables for the report parameters.

Everything works fine until I click a drill down link.

The error comes in the space where the viewer would be, and just says that the first report parameter has no value.

Sorry if this is a dumb question.

Persisting Package Variables

Apr 7, 2006

I was able to write successfully a Script Task to set the values of several package variables. But when the execution completes, the variables still contain values which were specified by default.

What I want is a method of persisting the values assigned to a variable through a script. I believe this was possible in DTS

InfoPath Form's Data To SQL / SSRS Database

Apr 11, 2008

Hi

In my current project we are dealing with a lot if Infopath forms of all sizes and complexities. currently they are being saved in Forms library of sharepoint.
We need to build a warehouse for SSRS which receives data either from content database or from infopath forms submit with minimum latency.
I thought of few alternatives, but, not sure which is most robust and economical.
1. Built c# classes to parse XML of infopath forms and then push data to SQL using ADO.net and SQL stored procedure while item is being added (ItemAdding) to Forms Library.
2. Use CAML queries to extract XML from forms library and then continue with C#/ADO/SQL..
3. Use SSIS APIs and webservices to massage XML and put it to SQL at ItemAdding event
4. Use CAML queries to generate XML files and stage it to FTP and rest will be done on SSIS.

I am currently looking for feseability information based of Besy Known Practise. Please feel free to suggest a totally new approach, if available.

Thanks

SQL CE Updates Not Persisting

Jun 7, 2007

I have a pocket pc app that is using a sql ce (.sdf) database. The inserts, updates and deletes are not persisting when I exit debug. It seems like it's getting put in the database because I bind drop down lists after the inserts, updates, etc and the new/changed data shows correctly after rebinding the data (when I repopulate the drop downs I make a call to the database, I don't just manually add the new item to the drop down so it seems like the changes are getting to the database). However, once I stop debugging and restart debugging all my changes are gone. I'm not using transactions but is there something that I need to do to commit the db changes?



Thanks

Reporting Services :: Referencing SSRS Variables Set In Report Properties

Jun 20, 2013

I am modifying a report that sets this variable at the beginning of every dataset:

declare @current_minute int
set @current_minute = DATEPART(N, GETDATE()) % 3

My idea is to set this variable in the Report Properties instead. When I do set this variable it in a Text Box or a Dataset, I get errors such as:

The expression used for the calculated field '=Variables!report_var.Value' includes a variable reference. Variable values cannot be used in calculated field expressions.

The Variable(report_var) expression for the report ‘body’ contains an error: [BC30451] Name 'N' is not declared.

What other strategies can I use to set a variable globally, instead of at the beginning of each dataset?

Persisting Data For A Pluggable Tree

Jul 23, 2005

Hi all,I am rather new to database design and modelling concepts in generaland was hoping for some advice on a problem I am trying to solve. Ihave designed a piece of software that creates a tree with pluggablenodes. Each node class can have 0 to n distinct classes plugged intoit to define the type for that node.For example, a node plugged with a 'customer' class and an 'engineer'class would indicate that this node in the tree is an engineer who isalso a customer. We could also have a 'owner', 'engineer' etc.I now want to persist this tree in an SQL Server 2000 Database. I havechosen to implement the nested set model, and have thought about thefollowing table design:table NODE_TABLE:lft INTEGERrft INTEGERpropsID INTEGERtable PROPERTIES_TABLE:propsID INTEGERtableName VARCHARtable CUSTOMER_TABLE:propsID INTEGERfirstname CHARlastname CHARtable ENGINEER_TABLE:propsID INTEGERnum_completed_projects INTEGERdegree CHARschool CHARtable OWNER_TABLE:propsID INTEGERcompanyName CHARSo, given the above example - I would have a NODE_TABLE that links to 2entries in PROPERTIES_TABLE. One entry would link to an entry in theCUSTOMER_TABLE, the other to an entry in ENGINEER_TABLE.Are there any more efficient solutions to this problem? As i said, Iam very new to DB design and would welcome any feedback or suggestionsof how else I might model my pluggable tree in a Database. Thank you,Bob Yohan

Persisting A SqlDataReader In A SqlFunction Enumerator

Mar 15, 2007

I have built a Table Valued SqlFunction which streams out filtered results from a table. The way that I have implemented this is by using a custom class which implements the IEnumerator interface.

The class internally stores a SqlDataReader and a SqlConnection as private member variables. The Class initializer (ie: the New function) creates a SqlCommand which is executed with ExecuteReader into the SqlDataReader and returns.

The IEnumerator.MoveNext method loops through the SqlDataReader until it finds a result which matches the heuristic filter, and the IEnumerator.Current method returns the current result from the SqlDataReader.

Unfortunately as soon as the initializer returns the SqlDataReader is automatically closed, and I can't figure out why. I've debugged through this and at the end of the Initializer the SqlDataReader is definately open, and as soon as first call to MoveNext is run it is closed.

Can anyone offer any suggestions on how I can fix this.

In the interim i've had to load all of the filtered results into a temporary ArrayList in the Initializer, which defeats the purpose of streaming out the results.

SQL Server 2008 :: Temp Tables Persisting In TembDB

Apr 30, 2015

I've recently started a new position and our production box. Contains a procedure that uses 30 + temp tables. I'm currently not in a position to change this as it's production and I would have to be granted a window to re-design.

However the tempDb is showing some strange activity.

If a table is created #CarrierService (CarrierServiceID,DeliveryZoneID,CollectionZoneID) for example

Once the procedure is called It will appear in the tempDB with the session info appended as expected

#CarrierService________________________________________________________2C78E45A

However once the session has ended the above table will get dropped and a new one created

#2C78E45A, I now have 7000 of these different Tables in the TempDB

When I Interrogate this using

SELECT o.name, o.create_date,o.modify_date , c.Name,C.Column_Id
FROM tempdb.sys.Objects o
Inner join tempdb.Sys.Columns c
ON o.object_id =c.Object_ID
WHERE o.type ='U'

I get the Following results

name create_date modify_date object_id name
#2C78E45A26/04/2015 18:0930/04/2015 14:55746120282CarrierServiceId
#2C78E45A26/04/2015 18:0930/04/2015 14:55746120282CollectionZoneId
#2C78E45A26/04/2015 18:0930/04/2015 14:55746120282DeliveryZoneId

Notice How It's getting Modified today.

Can I Use SSIS To Port Directly From ODS To AS And Bypass Persisting In Intermediate DW?

Jul 20, 2007

At this link here:




http://www.microsoft.com/technet/prodtechnol/sql/2005/dwsqlsy.mspx

I read this snippet here:




Push data from the Integration Services pipeline or a custom application. The data can flow directly into an Analysis Services partition from the Integration Services package pipeline, without intermediate storage. This scenario can be used to reduce the latency (and storage cost) of analytical data.

What I think this means is that using SSIS I could bypass porting the data from ODS to DW, and instead use SSIS control flow/data flow components to direct the data straight to the Analysis Services Cube database storage partition.



I was hoping by posting this thread on this MSDN forum I could get details or links from those more knowledeable than I on this subject pointing me to how I may go about using SSIS to implement this approach. Perhaps package code examples or instructions about the components I could use to do this?

XML Source Editor Columns Configuration Is NOT Persisting Output Name Selection

Oct 25, 2007

Greetings everyone,

I am seeing a particular problem in the XML Source Editor "Columns" configuration where it is not persisting the "Output name" selection.

Control Flow Tab:
1. I use a "Exec SQL Command" to drop, create, or alter the destination tables in the database that I want to be repository for the inbound XML data. The data types are fairly straightforward.

2. I add a singular "Data Flow"

Data Flow Tab:

1. I add a "XML Source" task, and assign a well-defined XML file. I then use the "Generate XSD" option in the "Connection manager"; and I am fairly satisfied with the generated XSD.

2. I create "OLE DB Destination"

3. I wire the "XML Source" to the "OLE DB Destination". In the "XML Source" in the "Columns".

4. I go to the dropdown list of "Output name" and see the list ordered with the various complex-types that I want to map and transfer to a target table.

For the sake of this report, I select the 5th one down on the list (for which I already have a target table) - let's call this "Mesh"

5. In the "Input Output" dialog, I select the "output" to be the desired 5th item, "Mesh"

6. I check all my mappings so that they map one-to-one ... XML name entries match SQL table destination mapping entries; correct types; correct size

7. Check the metadata and it all looks good.

8. When I hit "Debug" to test the package the failure occurs at the "XML Source". The error report comes back saying that it failed because "field xxx in Contributor was truncated". However, "Contributor" corresponds to the 1st name in the dropdown list presented in "Columns" "Output name:".

If I select return to Step 4, when I open up "Columns" I see that my previous selection of the 5th item on the list named "Mesh" was not persisted, but invariably and no matter how often I select item #5 "Mesh" and save to ensure that selection sticks, it is not persisted.

I hand-edited the .dtsx file and only then was I able to make this stick. However, if I ever re-save the package this non-persistency pops up again.

Am I doing something wrong here or is this a known defect? As I have several dozen XSD mappings that I want to transfer to tables, hand-editing is not something I relish.

I look forward to your reply.

One Form To Update Different SQL Tables Based Upon Form Selection

Apr 16, 2008

Hello,
My company Intranet has a form that agents can use to post their comments about the company to upper management, but our customer service department would like to modify the form so that the agent has to pick from a comment type.
The dropdown options on the form will be as follows:
ComplimentsComplaintsGeneral CommentsSuggestions
Each dropdown option has a designated table in a SQL DB.Using postback on the same page, I need to change which fields of the form are visible based upon which dropdown selection the user chooses, and I need the fields to then be inserted into the table that corresponds with the dropdown selection item.
For example: If the Compliments dropdown selection is picked, I need a text box to show for the user's location, the name of the customer, account number, and the message box. Once the submit button is clicked, the characters in these boxes need to be inserted into the Compliments table using its data adapter.
However, if the user selects Suggestions, the name of the customer and the account number should not be visible, since these fields do not exist and when the submit button is pressed, the Suggestions table should be updated.
If you need more information, I will provide whatever is needed.
As always, thanks for everyone's assistance.
Chris

How To Make The SSMSE To Return Whole Records Without Any Close Query Form And Re-create Query Form Operation?

Dec 25, 2007

Hi,
I got a problem.
I installed Microsoft SQL Server Management Studio Express 2005 version.
And I created a Compact database.
I created an connection in SSMSE to connect the database and opened a query form.
then, i run the following sql:

Select * from Table1

It returned 3 records to me.
After that, I used program to insert record into this table.
Then i ran this sql again, it still show me 3 records.
I closed the query form, and re-created a new query form, then run the sql, it returned 4 records to me.

Why? It's very strange and difficult to operate, right?
Is there anyone know how to make the SSMSE to return whole records without any close query form and re-create query form operation?

Thanks a lot!

And Merry X'max!!!

First Form Normalizations And Second Form Normalization

Jul 19, 2006

Hi everyone,
What is the main difference between first form normalizations and second form normalization ?
In my opinion, they are both generated for the same operation which is to prevent redundancy(in other words; duplication of data in several records).
So would you please explain it to me ?

Thanks

Execute DTS 2000 Package Task Editor (Inner Variables Vs Outer Variables)

Sep 4, 2006

Hi,

I am not comfortable with DTS 2000 but I need to execute a encapsulated DTS 2000 package from a SSIS package. The real problem is when I need to pass SSIS variables to DTS 2000 package. The DTS 2000 package have 3 global variables that I can identify on " Execute DTS 2000 Package Task Editor - Inner Variables ". I believe the SSIS variables must be mapped on " Execute DTS 2000 Package Task Editor - OuterVariables ". How can I associate the SSIS variables(OuterVariables ) to "Inner Variables"? How can I do it? Much Thanks.

How To Design A Package With Variables So That I Can Run It By Dos Command Assigning Values To Variables?

Jan 24, 2006

Hi,

I would like to design a SSIS package, which have couple of variables. It loads a xls file specified in a variable [varExcelFileFullPath] .

I will run it by commands: exec xp_cmdshell 'dtexec /SQL ....' (pls see an example below).

It seems it does not get the values passed in for those variables. I deployed the package to a sql server.

are there any grammar errors here? I copied it from dtexecui. It worked inside Dtexecui not in dos command.

exec xp_cmdshell 'dtexec /SQL "LoadExcelDB" /SERVER test /USER *** /PASSWORD ****

/MAXCONCURRENT " -1 " /CHECKPOINTING OFF /REPORTING EW

/LOGGER "{6AA833A1-E4B2-4431-831B-DE695049DC61}";"Test.SuperBowl"

/Set Package.Variables[User::varExcelFileName].Properties[Value];"TestAdHocLayer"

/Set Package.Variables[User::varExcelWorkbookName].Value;"Sheet1$"

/Set Package.Variables[User::varExcelFileFullPath].Value;"D: estshareTestAdHocLayer.xls"

/Set Package.Variables[User::varDestinationTableName].Value;"FeaturesTmp"

/Set Package.Variables[User::varPreSQLAction].Value;"delete from FeaturesTmp"

'

Can I Write SSRS 2008 Reports To Run On SQL 2005 SSRS?

Sep 12, 2007

Is it possible to write SSRS 2008 reports to run on an existing SSRS 2005 server?

If yes, what do I need to do to be able to write SSRS 2008 reports on my developer PC that will run on the SQL 2005 Server (which also has SSRS 2005 installed on it)?

I installed Visual Studio 2008 beta on the development PC and it appears that it needs SSRS installed on it too. So I installed SQL 2008 SSRS (SQL Server Reporting Services) and SQL 2008 Workstation Components onto the developer PC. Next I run the SQL 2008 "Reporting Services Configuration" tool. When I click on the "Web Service URL" section it hangs indefinitely and I have to force it closed.

The developer PC is Windows Vista Business.

Any suggestions on making this work, or any other information that you can think of that would allow me to use Visual Studio 2008 and the SQL 2008 "Report Designer Preview" tool to develop SSRS reports that will run on the SQL 2005 SSRS server?

Thanks!

Help Me Form This SQL?

Mar 2, 2006

Hi all, this'll be my first post here, hopefully I'll get this right and someone can help.

I'm trying to generate a subquery that will take a set of one-column rows and concatenate them into a single cell.

I've adapted from this article (http://www.sqlteam.com/item.asp?ItemID=2368) the following code:
DECLARE @topicList varchar(200)

SELECT @topicList = COALESCE(@topicList + ', ', '') + MAB_topics.topic_name
FROM MAB_topics

SELECT @topicList
that produces a list of all the topic_names in the database seperated by commas. That's fine.

I couldn't follow all the code in this thread (http://www.sqlteam.com/Forums/topic.asp?TOPIC_ID=18363) but I was able to extract and modify this code:

DECLARE @topicList varchar(200)

SELECT MAB_topics.topic_name
INTO #tmp
FROM MAB_topics, MAB_articleIndex
WHERE MAB_articleIndex.article_ID = 76 AND
MAB_topics.topic_ID = MAB_articleIndex.topic_ID

SELECT * FROM #tmp

drop table #tmp
which returns the two topic_names that I'd expect. (Note: this is my very first day declaring variables and using temp tables.) So I keep thinking that the following code would combine the two above working functions. But, when I run it in Query Analyzer, it just returns "(2 row(s) affected)" instead of a recordset.

DECLARE @topicList varchar(200)

SELECT MAB_topics.topic_name
INTO #tmp
FROM MAB_topics, MAB_articleIndex
WHERE MAB_articleIndex.article_ID = 76 AND
MAB_topics.topic_ID = MAB_articleIndex.topic_ID

SELECT @topicList = COALESCE(@topicList + ', ', '') + #tmp.topic_name
FROM #tmp

drop table #tmp
What am I doing wrong? I'm sure it's something simple but I've been reading and trying and reading and trying for a few hours and haven't gotten it yet. The ideal response would figure out what I'm trying to do as well as what my mistake is and explain how I'm misthinking. A close second would be just fixing my code. :)

Thanks in advance,

Chris

Form Problems

Jun 10, 2004

Can anyone help me with this problem? I have a form with three drop down lists. From these lists, the user selects an accountID, the territory that ID is from, and the territory that ID is transfering to. Upon submission, that account number is inserted into the table, along with the TerritoryID, RegionID, DivisionID, and EmpID associated with both of the territories selected. However, upon running this, the accountID and ToTerritory info are inserted once, but the FromTerritory data is inserted tens of thousands of times. Although they are not entered into the same record, which i eventually want to happen, i do want to figure out why so many duplicate entries for the FromTerritory are entered. Here is my code and the stored procedure to enter the FromTerritory. I would appreciate any help.
-------------------------

Sub InsertData()

Form With 20,500 Fields

Jan 27, 2004

I'm running SQL Server 2000. I have an interesting form I am creating for a client which has on it literally 20,500 fields that need to be stored in the system which I then have to create reports off of for statistics and trends.

I'm not sure how I should go about storing that large amount of information in SQL Server with the limitations of the size of a table. Would it be best to create 20 some tables to store it, or is there a better fashion to store it. 90% of the fields are numbers ranging from 0 to 100.

Thanks for any suggestions you can come up with!

How To Form The Query

Apr 5, 2008

I have two tables. The table is below.

Table name 1 : Income
Income RentMonth
1500 Jan
1500 Feb
1500 Apr

Table name 2 : Expense
Expense ExpMonth
200 Jan
300 Mar
400 Apr

The result table becomes (Profit=Income-Expense)
Profit Month
1300 Jan
1500 Feb
-300 Mar
1100 Apr

But I form the query by join the both Income and Expense tables to subtract the Income and Expense month wise.

But one moth is in one table the same month is not in another table.

For Example Feb month is in Income table, but not in Expense table.And Mar month is in Expense table and not in Income table. So how will I form the query to achieve my result table as i indicated above. Kindly help me.

Kamal.

Please Help! ASP Form To SQL Database

Apr 25, 2008

I'm using SQL server on godaddy.com, and for the life of me, tried all freakin day yesterday to get a form to send data to my table, and can't get it to work for the life of me

I think the asp form sends the information to the asp page that is to add the information to the tables correctly, but am not entirely sure, so here is the code for the form:

<html>
<head>
<title>Form Entry</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>
<body><form method="post" action="add.asp">
<table>
<tr>
<td>CustomerID:</td>
<td><input name="CustID"></td>
</tr><tr>
<td>Company Name:</td>
<td><input name="Company"></td>
</tr><tr>
<td>Contact Name:</td>
<td><input name="Contact"></td>
</tr><tr>
<td>Address1:</td>
<td><input name="Address1"></td>
</tr><tr>
<td>Address2:</td>
<td><input name="Address2"></td>
</tr><tr>
<td>Address3:</td>
<td><input name="Address3"></td>
</tr><tr>
<td>City:</td>
<td><input name="City"></td>
</tr><tr>
<td>State:</td>
<td><input name="State"></td>
</tr><tr>
<td>Zip:</td>
<td><input name="Zip"></td>
</tr>
<td>Email:</td>
<td><input name="Email"></td>
</tr><tr>
<td>Phone:</td>
<td><input name="Phone"></td>
</tr>
</table>
<br /><br />
<input type="submit" value="Add New">
<input type="reset" value="Cancel">
</form>
</body>
</html>


Now for the page that is giving me the problem (I think). I'm pretty sure I'm fudging up the connectivity somewhere because all I get is an http 500 error every time I try to upload the information.

Why won't it bloody connect?!?!

Also, is the DIM function on this page used to hide important information? If you guys can help me fix this, I'd be incredibly, incredibly greatful, I'm frustrated out of my mind!

<%@LANGUAGE="JAVASCRIPT" CODEPAGE="CP_ACP"%>
<html>
<head>
<title>piece of shit page</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

conn.Execute sql,recaffected
if err<>0 then
Response.Write("No update permissions!")
else
Response.Write("<h3>" & recaffected & " record added</h3>")
end if
