SSIS Script Task Alters Package Variable, But Variable Does Not Change.

Oct 25, 2006

I'm working on an SSIS package that uses a vb.net script to grab some XML from a webservice (I'd explain why I'm not using a web service task here, but I'd just get angry), and I wish to then assign the XML string to a package variable which then gets sent along to a DataFlow Task that contains an XML Source that points at said variable. when I copy the XML string into the variable value in the script, if do a quickwatch on the variable (as in Dts.Variable("MyXML").value) it looks as though the new value has been copied to the variable, but when I step out of that task and look at the package explorer the variable is its original value.

I think the problem is that the dataflow XML source has a lock on the variable and so the script task isn't affecting it. Does anyone have any experience with this kind of problem, or know a workaround?

Passing A SSIS Global Variable To A Declared Variable In A Query In SQL Task

Mar 6, 2008

I have a SQL Task that updates running totals on a record inserted using a Data Flow Task. The package runs without error, but the actual row does not calculate the running totals. I suspect that the inserted record is not committed until the package completes and the SQL Task is seeing the previous record as the current. Here is the code in the SQL Task:

DECLARE @DV INT;
SET @DV = (SELECT MAX(DateValue) FROM tblTG);
DECLARE @PV INT;
SET @PV = @DV - 1;

I've not been successful in passing a SSIS global variable to a declared parameter, but is it possible to do this:

DECLARE @DV INT;
SET @DV = ?;
DECLARE @PV INT;
SET @PV = @DV - 1;


I have almost 50 references to these parameters in the query so a substitution would be helpful.

SSIS: Problem Mapping Global Variables To Stored Procedure. Can't Pass One Variable To Sp And Return Another Variable From Sp.

Feb 27, 2008

I'm new to SSIS, but have been programming in SQL and ASP.Net for several years. In Visual Studio 2005 Team Edition I've created an SSIS that imports data from a flat file into the database. The original process worked, but did not check the creation date of the import file. I've been asked to add logic that will check that date and verify that it's more recent than a value stored in the database before the import process executes.

Here are the task steps.


[Execute SQL Task] - Run a stored procedure that checks to see if the import is running. If so, stop execution. Otherwise, proceed to the next step.

[Execute SQL Task] - Log an entry to a table indicating that the import has started.

[Script Task] - Get the create date for the current flat file via the reference provided in the file connection manager. Assign that date to a global value (FileCreateDate) and pass it to the next step. This works.

[Execute SQL Task] - Compare this file date with the last file create date in the database. This is where the process breaks. This step depends on 2 variables defined at a global level. The first is FileCreateDate, which gets set in step 3. The second is a global variable named IsNewFile. That variable needs to be set in this step based on what the stored procedure this step calls finds out on the database. Precedence constraints direct behavior to the next proper node according to the TRUE/FALSE setting of IsNewFile.


If IsNewFile is FALSE, direct the process to a step that enters a log entry to a table and conclude execution of the SSIS.

If IsNewFile is TRUE, proceed with the import. There are 5 other subsequent steps that follow this decision, but since those work they are not relevant to this post.
Here is the stored procedure that Step 4 is calling. You can see that I experimented with using and not using the OUTPUT option. I really don't care if it returns the value as an OUTPUT or as a field in a recordset. All I care about is getting that value back from the stored procedure so this node in the decision tree can point the flow in the correct direction.


CREATE PROCEDURE [dbo].[p_CheckImportFileCreateDate]

/*

The SSIS package passes the FileCreateDate parameter to this procedure, which then compares that parameter with the date saved in tbl_ImportFileCreateDate.

If the date is newer (or if there is no date), it updates the field in that table and returns a TRUE IsNewFile bit value in a recordset.

Otherwise it returns a FALSE value in the IsNewFile column.

Example:

exec p_CheckImportFileCreateDate 'GL Account Import', '2/27/2008 9:24 AM', 0

*/

@ProcessName varchar(50)

, @FileCreateDate datetime

, @IsNewFile bit OUTPUT

AS

SET NOCOUNT ON

--DECLARE @IsNewFile bit

DECLARE @CreateDateInTable datetime

SELECT @CreateDateInTable = FileCreateDate FROM tbl_ImportFileCreateDate WHERE ProcessName = @ProcessName

IF EXISTS (SELECT ProcessName FROM tbl_ImportFileCreateDate WHERE ProcessName = @ProcessName)

BEGIN

-- The process exists in tbl_ImportFileCreateDate. Compare the create dates.

IF (@FileCreateDate > @CreateDateInTable)

BEGIN

-- This is a newer file date. Update the table and set @IsNewFile to TRUE.

UPDATE tbl_ImportFileCreateDate

SET FileCreateDate = @FileCreateDate

WHERE ProcessName = @ProcessName

SET @IsNewFile = 1

END

ELSE

BEGIN

-- The file date is the same or older.

SET @IsNewFile = 0

END

END

ELSE

BEGIN

-- This is a new process for tbl_ImportFileCreateDate. Add a record to that table and set @IsNewFile to TRUE.

INSERT INTO tbl_ImportFileCreateDate (ProcessName, FileCreateDate)

VALUES (@ProcessName, @FileCreateDate)

SET @IsNewFile = 1

END

SELECT @IsNewFile

The relevant Global Variables in the package are defined as follows:
Name : Scope : Date Type : Value
FileCreateDate : (Package Name) : DateType : 1/1/2000
IsNewFile : (Package Name) : Boolean : False

Setting the properties in the "Execute SQL Task Editor" has been the difficult part of this. Here are the settings.

General
Name = Compare Last File Create Date
Description = Compares the create date of the current file with a value in tbl_ImportFileCreateDate.
TimeOut = 0
CodePage = 1252
ResultSet = None
ConnectionType = OLE DB
Connection = MyServerDataBase
SQLSourceType = Direct input
IsQueryStoredProcedure = False
BypassPrepare = True

I tried several SQL statements, suspecting it's a syntax issue. All of these failed, but with different error messages. These are the 2 most recent attempts based on posts I was able to locate.
SQLStatement = exec ? = dbo.p_CheckImportFileCreateDate 'GL Account Import', ?, ? output
SQLStatement = exec p_CheckImportFileCreateDate 'GL Account Import', ?, ? output

Parameter Mapping
Variable Name = User::FileCreateDate, Direction = Input, DataType = DATE, Parameter Name = 0, Parameter Size = -1
Variable Name = User::IsNewFile, Direction = Output, DataType = BYTE, Parameter Name = 1, Parameter Size = -1

Result Set is empty.
Expressions is empty.

When I run this in debug mode with this SQL statement ...
exec ? = dbo.p_CheckImportFileCreateDate 'GL Account Import', ?, ? output
... the following error message appears.

SSIS package "MyPackage.dtsx" starting.
Information: 0x4004300A at Import data from flat file to tbl_GLImport, DTS.Pipeline: Validation phase is beginning.

Error: 0xC002F210 at Compare Last File Create Date, Execute SQL Task: Executing the query "exec ? = dbo.p_CheckImportFileCreateDate 'GL Account Import', ?, ? output" failed with the following error: "No value given for one or more required parameters.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.

This occurs when the number of errors reaches the number specified in MaximumErrorCount. Change the MaximumErrorCount or fix the errors.

SSIS package "MyPackage.dtsx" finished: Failure.

When the above is run tbl_ImportFileCreateDate does not get updated, so it's failing at some point when calling the procedure.

When I run this in debug mode with this SQL statement ...
exec p_CheckImportFileCreateDate 'GL Account Import', ?, ? output
... the tbl_ImportFileCreateDate table gets updated. So I know that data piece is working, but then it fails with the following message.

This occurs when the number of errors reaches the number specified in MaximumErrorCount. Change the MaximumErrorCount or fix the errors.

SSIS package "MyPackage.dtsx" finished: Failure.

The IsNewFile global variable is scoped at the package level and has a Boolean data type, and the Output parameter in the stored procedure is defined as a Bit. So what gives?

The "Possible Failure Reasons" message is so generic that it's been useless to me. And I've been unable to find any examples online that explain how to do what I'm attempting. This would seem to be a very common task. My suspicion is that one or more of the settings in that Execute SQL Task node is bad. Or that there is some cryptic, undocumented reason that this is failing.

Thanks for your help.

SSIS With Variable

Jan 18, 2006

Newbie question. I'm new to using variables in SSIS. Are there any good examples around of how to return an @@identity value from a procedure and then use it globally within an SSIS package for multiple "execute SQL" tasks? I've gone though the documentation but don't find it to be very complete.

SSIS Variable That Should Contain Uniqueidentifier

Jun 26, 2006

Hi

I am importing data and wand to assign a fixed value to an output col. the fixed value should be a uniqueidentifier maintained in a variable so that it can easely exchange prior to execution. My problem is that I realized that there is no variable type for uniqueidentifier. When trying to store the guid in a string variable and then trying to cast back using a script component i received a casting exception telling me that a string cannot be converted into a guid.

I dont want to use an object type because then i would have to manually read out the variable a execution start.

Does anyone have experience using varialbes and guids?

Thanks a lot

Wondering ...Variable Use In SSIS

Aug 23, 2007

Hi,
I have a SSIS with a set of SQL Tasks that executes SPs, I need to add a precedence constraint which handles case of error, but as way to use only one SQL Task for Error... I think about using a variable that stores the SQL Task Name in turn and that can be used as a Parameter in the SQL task that I use with "sp_send_dbmail" to notify error..
That is..




________
|_sql 1__| --------
|
| ___________________
________ | sql handling Error |
|_sql 2__| -------->> |___________________|
|
|
________ |
|_sql 3__| --------



Need that Every SQL Task send its name as a parameter to my
"Sql handling Error Task" to be use with something like this code..



EXEC msdb.dbo.sp_send_dbmail
@profile_name = 'Profile',
@recipients = @MailRecipient,
@body = 'Error in' + @SQLTaskName,
@subject ='Error al ejecutar ...' ;


I want to receive the name of the failing task in message body or subject.
I need to implement it also is projects with SQL 2000 (with Global Variables). Would appreciate any help, Please : )

Executing A SSIS Package With Variable Changes From ASP.NET

Mar 17, 2008

I am trying to execute a ssis package, where a user will be able to excute the package from an ASP page, the user will select a file, this will be the source file for the SSIS package, this will change when ever the package is executed, I was thinking of just using a sqlClient.sqlCommand and editing the command text and excuting it that way, or through a SP, would this be the best solution? Is there a better solution? and if not what would be the SQL command to execute the package, along with editing the variable?

SSIS Datetime Variable Perfoming &&>= Instead Of &&>

Mar 1, 2007

The source table has timestamp column (Modified Date), which gets upated with each modification via an update trigger.

I store the MAX(modifieddate) in a DeltaExtractionHistory Table in the staging database for each extraction or package execution. Then in the next run, I need to pick the coulmns that have a greater datetime, than the last extracted MAX(ModifiedDate) in the DeltaExtractionHistory table for delta processing.

The OLEDB source has the following SQL statement:

SELECT * FROM [dbo].[MyTable] WHERE [ModifiedDate] > ?

with the following parameter:

Parameter 0 : dtLastModifiedDate

dtLastModifiedDate is an SSIS variable of type Datetime. I read the value of MAX(ModifiedDate) in this variable in a SQLExecuteTask prior to running the data flow task that contains the OLEDB source task.

The problem is - instead of extracting greater datetime, it also extracts the MAX(Modifieddate), which was already extracted in the last run. In other words instead of functioning as [ModifiedDate] > ?, it is functioning as [ModifiedDate] >= ?

because of this, the primary key gets violated on the target table. I think this is happening because the date is stored as "2007-03-01 11:56:34.550" in the table, but SSIS variable shows it in the data viewer as "01/03/2007 11:56:34 PM". It truncates the milliseconds and picks the same date again, because it thinks milliseconds .550 is greater than 000. But I am not 100% sure, may be it is only showing this in the dataviewer, but it contains the ms part as well. I tried using

SELECT * FROM [dbo].[MyTable] WHERE [ModifiedDate] > ? AND DATEPART(ms, MODIFIEDDATE) > DATEPART(ms, ?)

But it fails with an error that the provider was not able to parse the SQL and try storing the statement in the SQL variable. I could not succeed in that - the statement never parses with the parameters.

Can someone please help in this.

Thanks

@[System::UserName] Variable In SSIS

Apr 15, 2008

Hello everybody,

I'm executing SSIS package, like a datareader source in a report in SSRS. Everything it's ok. But, I'm using
@[System::UserName] variable like a add column to save the user that ran the package.

But it's incredible, when the user execute the report, the system don't save the login that opened the browser, neither the user that run the ssis service or user for ssrs service. This is catching the user that opened session in the host where Sql server was installed.

I need catch the user that run the report, how can i do this?

Viewing Variable Values That Are Passed In To SSIS

Apr 16, 2008

Since SSIS is developed in Visual Studio is there a way to view the variable values as they are passed into SSIS? In Visual Studio I know if you hover over the variable a popup appears with the value in the variable.

I am having an issue with a variable value that is supplied through an "Execute SQL Task" it is a Directory path that is entered in through the application and used to determine where to pick up files to transfer. I have entered in the path using Fully Qualified(D:ImportExportCentralPrinting) and UNC (\SQLDEVELOPImportExportCentralPrinting) through both methods SSIS is telling me no files are available in the directory path. When I know for fact they do exists.

I would really love to see the variable values that are being used can anyone out there help?
Thank you all,

This is my first post. :-)

I've been having an error with Script Tasks in SSIS, where the error is every time I use a For Each In Dts.Variables, it always seems to crash. I'm trying to log the variables before I proceed in any other tasks. I'm passing in one value as a ReadOnlyVariables.

Here is the snippet of code:

Dts.Log(String.Format("{0} variables:", Dts.Variables.Count), 0, Nothing)
For Each v As Variable In Dts.Variables
Dts.Log(String.Format("{0} = {1}", v.Name, v.Value), 0, Nothing)
Next

It's very strange because the Dts.Variables.Count gives me the correct number of items that I have passed in, but after I step into the For Each, I get this for Dts.Variables.Item:

In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user. Microsoft.SqlServer.Dts.Runtime.Variable

And as soon as I step into the next line, it crashes with this error:

Value does not fall within the expected range.
at Microsoft.SqlServer.Dts.Runtime.Wrapper.IDTSVariables90.GetEnumerator()
at Microsoft.SqlServer.Dts.Runtime.Variables.GetEnumerator()
at ScriptTask_932938a13af547149ade0331cf39ecfe.ScriptMain.Main()


My colleagues have tried this snippet of code and it worked fine on their machine, only mine has this error :-(

I tried to do several searches online and they recommended me to:
Get the latest SP (I have all the updates now for .net and SQL)
Re-register some .dll's such as dts.dll/pipeline/etc
Change/toggle the PreCompileBinary
Alter the script a little and rebuild.

None of these suggestions have had any success on this error that I'm having. I was wondering if anyone had any insight or had any similar problems as me. Any help would be much appreciated!

Thanks,
-Simon

SSIS String Variable Is Truncating Data

Sep 25, 2006

Greetings,


I have written a SSIS package which does the following:


- An 'Execute SQL Task' uses an OLEDB connection to execute a Stored Procedure in SQL Server 2005
A SSIS user defined variable named @SourceSQLStatement is passed to the Stored procedure as an OUTPUT
This variable is a string Data Type

- The Stored Procedure generates an SQL command and saves it in the variable
This variable is defined as @SourceSQLStatement nvarchar(4000) OUTPUT
The varible is then returned to the SSIS package


When the package is executed the variable does not contain the entire SQL command.
When I check in the Locals window during Debug, the contents seem to have been truncated:


+ User::SourceSQLstatement {SELECT a.FailureID, a.ExceptionHandlerID, a.FailureTypeCd, a.AccountNbr, a.AccountNm, a.CaseNbr, a.CustNm, a.AssociateNm, a.TargetSysNm, a.FailureDt, a.FailurePointTxt, a.SubmittedByNm, a.ErrorMsgTxt, a.CreateId, a.CreateDt, a.UpdateId, a.UpdateDt FROM GSPIntegrationException a WHERE a.CreateDt >= (select max(ETLC.RunDt) from X141572_ETLSTAGING.dbo.ETL ETL inner join X141572_ETLSTAGING.dbo.ETLControl ETLC on ETL.ETLID = ETLC.ETLID inner join X141572_ETLSTAGING.dbo.ETLRun ETLR on ETLC.ETLID = ETLR.ETLID an} String


The fully generated SQL command does not exceed the 4000 character length provided in the stored procedure.
Has anyone encountered this issue before?

Any help would be greatly appreciated

Thank You
