Using Execute SQL Task Expression With Variables
Jan 15, 2008
I have a package with variables which are set to default values, in this instance table names.
I then use a script task to change these variable values, these change fine and I have looked in the watch window whilst debugging to ensure that the values have changed correctly, and they have.
My Script Task then pipes to a Execute SQL Task, where I am using Expressions to set the SqlStatementSource. The Expressions statement uses the variables I change in my script task to form a SQL query.
However, at run-time the Expression appears to be fixed with the default variable values, it does not change even though the variable values have changed. Below is an extract from my expression for the SqlStatementSource.
i.e
Code Block
"USE [DBNAme]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_PADDING ON
GO
CREATE TABLE [dbo].["+ @[User::StagingEventLossTable] +"](
[PolicyId] [varchar](50) COLLATE Latin1_General_CI_AS NULL,
<snip>
...
Is an Expression value fixed from the moment the package is run and is therefore not dynamic during run-time?
If this is the case, how can I get around this? As I want to be able to change this SQL Statement on the fly at run-time.
Thanks

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.

"Select * into @[User::varOutTable] from @[User::varFromTable]"
but the task failed,
it seems that sql task can't get the varOutTable and varFromTable
How can I use the Variables in SQL Execute SQL task?

Hi there
I'm attempting to update a variable using the Execute SQL task, I've read a lot of posts on this and seems reasonably simple but obviously not. The first time I ran it the variable was updated correctly, I then manually changed the variable value and since then it doesn't work.
I have a task with the following properties;
Resultset: SingleRow
SQLStatement: SELECT MAX(Player_Daily_Data_Pull_Date) as 'PlayerDaily' From Job_Control
On the resultset tab I have the resultsetname = PlayerDailyand the variable I want to update.
The variable has a type of datatime and it's scope is the container that I'm running the sql task within.
Any help would be appreciated.

I am trying to run a simple update (just to establish it works) passing in a variable in the execute SQL task. It is within a Foreach loop and the incoming data is from a RecordSet destination. One of the fields in the recordset is UniqueID. I have a variable called User::UniqueID which holds the uniqueID value. I then have a second variable which is the insert statement of
"INSERT rptlifespan_transactionimagecopy SELECT " + (DT_WSTR, 20)@[User::UniqueID] + ", null, null,null,null,null,null,null"
with delayvalidation set to True.
when I run the package i get the following error:
Error: 0xC0014054 at Execute SQL Task: Failed to lock variable "INSERT rptlifespan_transactionimagecopy SELECT 543, null, null,null,null,null,null,null" for read access with error 0xC0010001 "The variable cannot be found. This occurs when an attempt is made to retrieve a variable from the Variables collection on a container during execution of the package, and the variable is not there. The variable name may have changed or the variable is not being created.".
543 is the value of my first UniqueID so that bit is working ok. What I do not know is why the insert statement is failing.
Please help i have very little hair left!!

Somebody provided me with this link http://www.sqlis.com/58.aspx that helped me understand Execute SQL Task and how to assign values to variables from a resulting SQL query.
But I'm not sure if this tutorial addresses my particular example.
Here is what I'm trying to do.
I have a a simple table called VarTable with 2 columns. Col1 is called VarName, and Col2 is called VarVal. As you may have guessed from the column names, I want to hold variable and value pairs in this table.
Right now, I have 2 entries as follows.
Var1, Hello
Var2, Bye
I want to assign Hello and Bye into two variables in my package.
In using the above tutorial, I figured out how to assign one variable by doing the following SQL and using "Single row" Result Set property.
Select VarVal from VarTable
Where VarName = 'Var1'
Then in Result Set section of the Execute Task Editor I map VarVal with one of my user variables.
How do I take care of the 2nd variable in the same Execute SQL Task, or do I need to have another Execute SQL Task? Based on my understanding, in order for me assign multiple variables in one Execute SQL Task, I need somehow construct a SQL statement to return as many columns as I have variables to assign, but this seems hard to do given the variable table structure I have.
Please let me know if my example is unclear.

I have 3 Execute SQL tasks to find the max value of some fields. In two tasks the SQL
SELECT MAX(field bigint)
FROM TABLE
Is returned and stored as a string variable. My 3rd execute SQL task is
SELECT MAX(field int)
FROM TABLE
Is returned and stored as an object type. If I try to save it as a string, the execution fails with a mismatch.
WHY? Why aren't they all strings? What am I missing/doing wrong? This is very frustrating behavior. The queries are running against tables on SQL Server 2005 the field types are listed in the SQL above.
Thanks,
Matt

Hi,
I need to run an SQL command, in which one of the fields is based on the current time, represented as a string in a specific format.
I used a script task to create the string from the current time, and store it in a package variable named "newDate". Later, in the execute sql task, I have the following update statement: "update table_1 set field_1 = ?" (OLE DB connection is used)
and in the parameters mapping I set parameter 0 to the string package variable "newDate".
The problem is that on runtime, the sql executes with the default value of the variable - i.e. it doesn't take the new value.
I checked it and placed another script task after the first one, that simply tries to read the variable "newDate" and print it to screen, but even here the default value is used.
how can I use the new value of the variable?
thanks.

Hi,
I am having trouble getting the Execute SQL Task to recognize the package-level variables in an SSIS package. The tasks fail execution. The package contains three Execute SQL tasks and none of them receive the variables. However, when I replace the '?' in the code with the variable values they execute fine. These are the steps I have taken thus far:
Made sure the three variables are package level.
Verified I'm using an OLE DB valid connection.
Verified the variables are properly mapped in the parameters mapping section of the task properties.
Tried all 4 types of variable to parameter mapping (even though '?' in the query and '0,1,2..' in the name should work).
Changed the Bypassprepare property to 'True'.
Breakpoints and watch windows to verify the variable values.
I actually tried the simple tutorials on a one-liner SQL statement that uses variables, but had the same problem. I know there must be something simple that I'm missing here, but any info would be greatly appreciated!
Thanks!

Hi All,
I was wondering if it is possible to assign values to multiple variables from within the same execute sql task, ie I want to use only one execute sql task and have multiple T-SQL statements within it and then assign the results of these sql statemenst as values to multiple variable.
Typically I would declare variables var1 , var2 and var3 , then can I just add one execute sql task and have mutiple sql statements within it? something like this
select max(id) from table1
select max(id) from table2
select max(id) from table3
Thanks

Hi,
Let's say I have a package taking as parameter "InvoiceID". I want to execute this package as a child in another package. The parent package gets the list of invoices to produce and calls the child package for each entry of the list.
How do I pass the InvoiceID to the child? I know I can use the parent's variables from the child but I don't want the child package to be dependant on the parent package. For example, I might want to execute the "child" package as a stand-alone in development (providing it with a predefined InvoiceID). I might also want to call the same child package from another parent package with other variable names.
What I would like to do is "push" the value instead of "pulling" it. I know it's possible using the command line and the /SET option (ex.: /SET Package.Variables[InvoiceID].Value;' 184084)... Is it possible using the Execute Package Task?
Thanks

I am running my "execute process task" in a foreach loop that uses two variables (file paths) from the recordset that feeds into it.
My executable line looks like this: C:Program FilesWinZipWZZIP.EXE ,
which runs the command line Winzip executable and my argument line looks like this: -rp @ZipArch @ZipTxt.
When I replace the variables with literal strings, the process works (only once, of course).
My Argument won't parse in the expression editor, nor does the process run when embedded in the foreach loop. What am I doing wrong? Thanks for your help.

Hi there,
I'm creating an SSIS package that will execute legacy dts packages. The package to be executed is decided at runtime using a sql query task.
Executing a dts package statically works fine, but when I try to set the details of the dts to be run via expressions, I get the error below.
To make it dynamic, I created a variable of type string, and put the package name in here. I also have a string variable for the packageid. Then I set up an expression on the Execute DTS 2000 Package Task that sets the PackageName & PackageID property to this variable.
The PackageId is a string variable I've retrieved using:
select top 1 name,
cast(id AS varchar(50)) id,
cast(versionid AS varchar(50)) versionid
from sysdtspackages
where name = @PackageName
order by createdate desc
When I use the task to set the package id it works find (by selecting a dts, then changing the name), but when I try to provide the package id I get this message:
Error: 0x0 at Execute DTS 2000 Package Task: System.Runtime.InteropServices.COMException (0x8004040E): Invalid GUID specified.
at DTS.PackageClass.LoadFromSQLServer(String ServerName, String ServerUserName, String ServerPassword, DTSSQLServerStorageFlags Flags, String PackagePassword, String PackageGuid, String PackageVersionGuid, String PackageName, Object& pVarPersistStgOfHost)
at Microsoft.SqlServer.Dts.Tasks.Exec80PackageTask.PackageUtils.LoadDTS8Package(String pkgSrc, String sourceUser, String sourcePwd, Int32 srcType, Boolean bUseTrustedConnection, String packageName, String packagePassword, String packageID, String packageVersionGUID)

at Microsoft.SqlServer.Dts.Tasks.Exec80PackageTask.Exec80PackageTask.ExecuteThread()
Task failed: Execute DTS 2000 Package Task
but the method signature specifies String PackageGuid, and it is a string..
any ideas??
i tried casting the variable like so:
(DT_GUID) @[User:TSPkgId], as the versionid is a uniqueidentifier on sysdtspackages.. It didn't like that at all (can't cast from type DT_WSTR to DT_GUID error code 0xC00470C2)

Hello,
I am having a hard time setting the executable path for an Execute Process Task in SSIS. I have a variable that is initialized at package statup which holds the path to an executable in Windows. When I set the property "Executable" Path in an expression, I get a warning that the path for the executable is not set. One workaround was to try and initialize the variable with a bogus path with the hopes that the "correct" value will be written on run-time. NO LUCK. I still get the error and I cannot run the package until I put a static path.
Does anyone have a clue as to what is going on??

I've got a package in SSIS 2012 that has an Execute SQL task in the control flow level.
The SQL in question does an Upsert via the SQL merge statement. What I want to do, is return the count of records inserted and records updated (No deletes going on here to worry about). I'm using the output option to output the changed recs to a table variable.
I've tried returning the values as:
Select Count(*) as UpdateCount from @mergeOutput where Action = 'Update'
and
Select Count(*) as InsertCount from @mergeOutput where Action = 'Insert'
I've tried setting the resultset to both Single rowset and Full rowset, but i'm not seeing anything returned to the package variables I've set for them (intInsertcount and intUpdatecount).

I am using SSIS 2012 to dynamically backup stored procedures on a list of Servers and Databases.Here are the steps in my package,
1. Execute SQL Task: Captures a result set (configured to save the data set in an Object variable) with all the Servers and Databases on which stored procedures exist.
2. For each loop that is configured to get each each row(server name @[User::Server_Name] and databases name @[User::DataBase_Name]) from the object variable (@[User::Connection_Strings])and pass it to a connection manager that has an expression for servername
and database name.
2a) Â Within the for each loop, i have an execute process task that is configured as
 i) Executable:  C:WindowsSystem32WindowsPowerShellv1.0powershell.exe
 ii) Arguments:  Configured this to fetch value from an expression. The expression i am using is,'C:batch - CopyPowerShell Scripts to Backup Stored ProceduresScriptOutSPs.ps1' -$Server_Name "+ @[User::Server_Name]+ " -$Database_Name "+ @[User::DataBase_Name]
      Â
Note:  @[User::Server_Name] is the Servername from object variable and so is @[User::DataBase_Name] for database name . The execute task is to run a command line that triggers a powershell script with parameters. Here is the powershell script that i am using,
param([String]$Server_Name,[String]$Database_Name)
$Server = $Server_Name
$Database = $Database_Name
$savePath = "SalesDepartmentsData ScienceUsersSANDEEP PStoredProcedures_Backup"
[code]...
When i execute the script, by passing parameters from arguments, it executes successfully but nothing happens. Passing wrong arguments in the expression?

OK. I give up and need help. Hopefully it's something minor ...
I have a dataflow which returns email addresses to a recordset.
I pass this recordset into a ForEachLoop configuring the enumerator as (Foreach ADO Enumerator). I also map the email address as a variable with index 0.
I then have a Execute SQL task which receives this email address as a varchar variable (parameter 0) which I then use in my SQL command to limit the rows returned. I have commented out the where clause and returned all rows regardless of email address to try to troubleshoot this problem. In either event, I then use a resultset to store the query result of type object and result name 0.
I then pass this resultset into a script variable to start parsing the sql rows returned as type object. ( I assume this is the correct way to do this from other prior posts ...).
The script appears to throw an exception at the following line. I assume it's because I'm either not passing in the values properly or the query doesn't return anything. However, I am certain the query works as it executes just fine at the command prompt.
Try
ds = CType(Dts.Variables("VP_EMAIL_RESULTS_RS").Value, DataSet)
My intent is to email the query results to each email address with the following type of data by passing the parsed data from the script to a send mail task. Email works fine and sends out messages but the content is empty. I pass the parsed data as string values to the messagesource and define the messagesourcetype as a variable in the mail task.
part number leadtime
x 5
y 9
....
Does anyone have any idea what I might be doing wrong?
thanks

Dear all:
I had got the below error when I execute a DELETE SQL query in SSIS Execute SQL Task :
Error: 0xC002F210 at DelAFKO, Execute SQL Task: Executing the query "DELETE FROM [CQMS_SAP].[dbo].[AFKO]" failed with the following error: "The transaction log for database 'CQMS_SAP' is full. To find out why space in the log cannot be reused, see the log_reuse_wait_desc column in sys.databases". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
But my disk has large as more than 6 GB space, and I query the log_reuse_wait_desc column in sys.databases which return value as "NOTHING".
So this confused me, any one has any experience on this?
Many thanks,

I'm looking for a way to refer to a package variable within any
Transact-SQL code included in either an Execute SQL or Execute T-SQL
task. If this can be done, I need to know the technique to use -
whether it's something similar to a parameter placeholder question
mark or something else.
FYI - I've been able to successfully execute Transact-SQL statements
within the Execute SQL task, so I don't think the Execute T-SQL task
is even necessary for this purpose.

I'm doing Derived Column transformations, using a Findstring expression to locate field seperators in a column, and then a Substring expression to move the string data at those field seperator locations into a new column.
At the moment I'm using two Derived column transformations, one to store the result of the Findstring in a new column, and then a second to actually move the data into a new column with the Substring.
Is it possible to assign the result of the Findstring expression to a variable, that I can then use in the Substring expression? This would allow me to do the whole thing in one transformation

I'm using SSIS in Visual Studio 2012. My Execute SQL Task calls a Stored Procedure where I have a TRY-CATCH. Last week there was a problem and the CATCH was executed and logged an error to my error table, but for some reason the Execute SQL Task didn't fail. Is there a setting to make the Execute SQL Task fail when an SP encounters a failure?

I am using SQL 2005 SSIS. I am joining several large tables and then the move result into another table in the same database.
I would like know which method is faster:
Use Execute SQL Task to insert the result set to the target table
Use the Data Flow Task to insert the result set to the target table. (Use OLE DB source to execute SQL command and then use the SQL destination)
Could you tell me why then other is slower?
Thanks.

In the Control flow tab, I have an Execute SQL Task that outputs full Result set into a variable of an object type. Now how can I write the contents of the Full Result Set into a text file using Script Task. I also want to format the following way while I output into a file:
Column Name 1 : Column Value
Column Name 2: Column Value and so on
I tried writing the contents of the Object Variable into a file, but the file had an output of single word: System.__ComObject.
Code for Writing the Full Result Set into a Text File
Dim RSsqloutput as String = Dts.Variables("objVariable").Value.ToString
Dim strVal as String = "File completed on " & Now() & vbCrLf & "------------------------------------------------------" & vbCrLf
oLogFile.WriteAllText("C:MyFile.txt", strValue)
oLogFile.WriteAllText("C:MyFile.txt", rsSQLOutput)
I went through this link that explains how to write XML Result Set into a File, But this doesn't help as it writes in XML format.
Would you please give me a hint of code how I can go upon.

Hi everyone,
For first time I'm testing this task and surprisingly, when I try "Edit Package" option:
1)The DTS host failed to load or save the package properly
2)The selected package cannot be opened
3)Error HRESULT E_FAIL has been returned from a call to a COM component
But after these messages you can see all the tasks but they haven't name!!
It seem as if RCW mechanism has failed between managed and unmanaged coded-partially.
I don't dare to follow doing more stuff, I don't know if that package is well-loaded or not from there. ?¿
Any guidance or idea about this?

An Execute SQL task takes 1 min to run a statement "insert into Mytable select * from view_using_joins"
Output: 10,225 rows affected.
But a Dataflow task configured to fetch data from the same view_using_joins into MyTable takes hours to do the same.
Could you please explain why is it so ?

I want to use Navigation to click-through to another report.
However, the source report is an MDX summary report, and the report I'm calling needs the entire Customer MDX tuple as a parameter. (the entire customer tuple is not available in my cube)
The text box has enough information to identify the customer, but not the entire tuple.
I want to pass the text box contents to a SP which returns the MDX string, and pass that to the new report.
I do not see how using another data source can help me accomplish this.
Basically, I am wondering is there a way I can have an expression similar to
=EXECUTE(spX, parm=txtbox.Value)
Thanks In Advance for any help...
