OLE DB Source, SQL Command From Variable
Apr 15, 2008
I read several posts on this topic and I would like to confirm my understanding.
This question has to do with parameterizing the select statement in the OLE DB Source editor. Initially, I thought I could use Data access mode: SQL command, and somehow use a user variable in there to build my Select statement.
But in researching further, it looks like I need to store the entire SQL command in a one long string variable (let's call it A), where A is built off of another variable that has my parameter. I then use A in Data access mode: SQL command from variable.
Am I correct? And is there not a way to accomplish the samething with only one variable that is your parameter value?
It seems a bit clumsy to store the entire SQL expression in a string variable.

Using Jamie's, John's and Rafae post i have got this far.
My scenario demands me to do an incremental load. So i have followed your article and have created a one variable 'vDate' (Dataflow Task, Datetime, 3/3/2008) and another variable SourceSQL (Dataflow Task, String). I have set this SourceSQL evaluation to True and have added this;
"select * from stagingperfdata where startdatetime = "+ (DT_WSTR,10) @[vDate].
I want to call this within a OLE DB source, so i select the data access method to SQL command from variable. My variable name is visible and i am able to select it and then save and debug. I also have a derived column transformation to increment the variable vDate by one day.
The flow is successful but there is no records written to the target.
I tried the same query (available in the variable's value column) in SSMS and it is retrieving 12 records.
I went back to the Ole Db source and wanted to preview the data, but i get "Query timeout expired (Microsoft SQL Native Client)" error.
Am i missing something fundamental?

Hi,
I have to read data from an MDB file into SQL Server. Simple, but I need to place a literal into every row. In my OLE DB Source I would use:
SELECT '001' AS col1, foo, bar FROM Table1
But the problem is that I pass my value for col1 into the package from C# using Managed DTS.
So I set up my OLE DB Source using "SQL command from variable." And I have two variables one to receive the value of for col1 (col1) and one that is an evaluated expression that has a dynamic sql statement (dynSql).
col1 is a String as is dynSql. dynSql looks like this:
"SELECT " + @[col1] + " as col1, foo, bar FROM Table1"
Now as long as I set the value of col1 to '001' that should work. Right? Well not exactly. The destination for col1 in SQL Server is a char( 3 ). But the package makes the col1 column from the source a DT_WSTR. Which causes the famed: "Text was truncated or one or more characters had no match in the target code page.".
Is there a better solution?
Thanks. Kenneth.

Hi All,
i am using a OLE DB Source in my dataflow component and want to select rows from the source based on the Name I enter during execution time. I have created two variables,
enterName - String packageLevel (will store the name I enter)
myVar - String packageLevel. (to store the query)
I am assigning this query to the myVar variable, "Select * from db.Users where (UsrName = " + @[User::enterName] + " )"
Now in the OLE Db source, I have selected as Sql Command from Variable, and I am getting the variable, enterName,. I select that and when I click on OK am getting this error.
Error at Data Flow Task [OLE DB Source [1]]: An OLE DB error has occurred. Error code: 0x80040E0C.
An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80040E0C Description: "Command text was not set for the command object.".
Can Someone guide me whr am going wrong?
myVar variable, i have set the ExecuteAsExpression Property to true too.
Please let me know where am going wrong?
Thanks in advance.

Hi,
I want to transform an xml flow to an html flow. For this, I create an XmlDataDocument, I add on it, all that I want, and I store it in a file (in a dataflow task).
After that, in an xml task, I set the input properties like that:
Operation type: xslt
SourceType: File connection
Source: ras.xml
All works fine. But now, I want to use a variable to store my xml data. So, instead of storing my data in ras.xml, I store it in a variable like that:
Dim v As Microsoft.SqlServer.Dts.Runtime.Wrapper.IDTSVariables90
Me.VariableDispenser.LockOneForWrite("RAS", v)
v("RAS").Value = doc.OuterXml
v.Unlock()
and in the xml task, I set configuration like that:
Operation type: xslt
SourceType: Variable
Source: user::RAS
But when I execute, I got this following exception:
Error: 0xC002F304 at Format HTML Mail, XML Task: An error occurred with the following error message: "Root element is missing.".
Error: 0xC002928F at Format HTML Mail, XML Task: Property "New Source" has no source Xml text; Xml Text is either invalid, null or empty string.
Furthermore, when I want to debug it, in replacing the xml task, by a script task, I can see that in my RAS variable, I get the xml data which is well formed.
<?xml version="1.0" encoding="UTF-8"?>
<root> €¦
</root>
(When I store it in a file, I can see it in IE)
Have you got an idea ?

Hi,
I am trying to set the OLE DB Source Editor. I am using the following option for Data Access mode
SQL Command from a variable and uses my sqlQuery variable.
sqlQuery variable contains a sql statement but I am getting the following error
ox80040E0C, Command text was not set for command object,
Additional information HRESULT 0xC0202009
Does it mean I have to give the variable name containing the stored procedure?
Please Guide

I created a Stored Proc to compute all the data I need to export to a CSV file.
I use the provider MS OLE DB Provider for SQL Server.
It's a very simple package with a single Data Flow Task.
This flow task is using an OLE DB Source to call a simple SQL Command : Exec MyStoredProc.
There are no params.
This Stored Proc is using table variables to compute the data.
It takes about 10 seconds to return anything.
The problem is that the mapping doesn't work with the OLE DB Source.
There are no fields at all shown in the mapping screen.
I tried to replace the Stored Proc by a version which only returns fields and no data.
Then the mapping would work just fine.
The package is then compiling and working fine.
But everytime I put back the real stored proc, even without changing the SQL Command, the SSIS execution breaks at execution.
It keeps saying :
"Error: 0xC0202005 at Data Flow Task, OLE DB Source [477]: Column "RecordType" cannot be found at the datasource."
My guess is that SSIS doesn't wait the 10 secs and thinks the Stored Proc is not returning anything.
What can I do to make this work ?
Thanks,
Vincent

Hi All,
I have a requirement to create a dynamic SQL Command in an OLE DB Source due to the fact that I need to read data from another database based on a date range. For example, the SQL command would look like
SELECT * FROM Table1 WHERE DateField BETWEEN '17/03/2008' and '21/03/2008'
and I need to change the dates - '17/03/2008' and '21/03/2008' to different dates when the package is deployed in production, how do I do that ?
Regards
Ash

I'm having difficulty passing a date parameter in a SSIS OLEDB connection to a stored procedure using SQL command with the error message "Attempted to read or write protected memory ..." and if I create a variable, I get the error "must declare the scalar variable..". Here is the OLEDB command: "EXEC dbo.mic_TGDrop ?" where ? requires a date parameter @ReportDate. Why does the call to the stored procedure fail? What would be the correct syntax of a variable to use SQL Command from variable? The SQL BOL does not cover this; is there another resource that has a simple example? Thanks.

I got a package with data flow task. Within the data flow task I have flat file with Fiscal Calendar defined. I got another data source within the data flow task, which is OLE DB Source. I want to use SQL Command as data access mode. SQL similar to one the below is in there.
----------------------------------------------------------------------------------------------------
DECLARE @startdate DATETIME
DECLARE @enddate DATETIME
DECLARE @date DATETIME
DECLARE @id INT
SET @startdate = '1993-09-26' --Change these to
SET @enddate = '2010-09-25' --whatever you want
SET @id = 1
SET @date = DATEADD(dd, @id, @startdate)
WHILE @date <= @enddate
BEGIN
select @date CalendarDate,
DATEPART(dd, @date) CalendarDayMonth,
DATEPART(dy, @date) CalendarDayYear,
DATEPART(dw, @date) CalendarDayWeek,
DATENAME(dw, @date) CalendarDayName
SET @id = @id + 1
SET @date = DATEADD(dd, @id, @startdate)
END
----------------------------------------------------------------------------------------------------
This SQL works fine in SSMS and returns around 6000 rows. But when I plug the same SQL in OLE DB Source it returns only the first record. It is not going through the WHILE loop.
Has anyone came across this?
Thanks

Happy new year everyone!!!
Ok, now for my not so happy new year problem ... here's the scenario:
I have a simple task of exporting data retrieved by a parameterized stored procedure to a delimited text file ... task done in 30 mins max using dataflow task from OLE DB Source with SQL Command to Text File Destination ... thank you very much SSIS!
But the problem is the OLE DB Source executed the SP MULTIPLE TIMES (3 to be exact)
Actually configuration is:
1. OLE DB Source
2. SQL Command access mode
3. The following command written in the command text box:
SET FMTONLY OFF;
exec sp_SampleSP @param1=?, @param2=?
4. Configured parameter mapping.
The stored procedure logs to a database table everytime it is executed to report how many rows were selected (please don't crucify me with this method, i'm re-using procs from old system). The log shows that during execution of this package the SP was executed on 3 times.
Help anyone? Please ...

Using SQL Server 7.0, I am trying to use a variable string called from a form to perform a simple query.
Here's what it looks like:
[after submitting a form on the previous page with a drop down list box titled "fiscal"]
dim strYear
strYear = Request.Form("fiscal")
sql = "SELECT * FROM VENDOR WHERE STATUS = 'P' AND '"& strYear &"';"
[where strYear is the following: PYMNT_DT > ''12/31/98'']
Records exist that meet this criteria. If the PYMNT_DT > '12/31/98' is hardcoded into the sql statement, 12 records are returned. However, when the variable string is used instead, no records are found. Any ideas on how this problem might be fixed?
Thanks in advance.
Sincerely,
Chad Massie

This is a really simple question. When I set my variable (the one will hold my SQL Command) property "EvaluateAsExpression=True", I don't get the option to edit the expression, I was expecting to get a little button that would open the "Property Expressions Editor" if pressed.
Am I doing anything wrong? Should I edit my SQL Command somewhere else and then Copy+Paste on my variable expression?
I need to pass a ServerName as a field to my query and I'm doing that by looping through a list of servers...

Hello everyone!
Bit of a problem executing a DTS command from a command line.
I have the following variables defined in my package:
UserVarchar1
UserVarchar2
UserVarchar3
All have a scope of Package, all of the mstrings
The command I'm attempting to run in 1 line is:
DTEXEC /FILE "C:SSIS PackagesED-CustomersPackage.dtsx"
/SET Package.Variables[User::UserVarchar1].value;"10"
/SET Package.Variables[User::UserVarchar2].value;"30719"
/SET Package.Variables[User::UserVarchar3].value;"BILLTO"
Description: The package path referenced an object that cannot be found: "Package.Variables[User::UserVarchar1].value". This occurs when an attempt is made to resolve a package path to an object that cannot be found.
DTExec: Could not set Package.Variables[User::UserVarchar1].value value to 10.
Any idea why?
Thanks for the help!

I was not able to find the solution myself so here I am to ask you.
I'm using an Ole DB Source with the SQL command from variable.
My variable expression needs to look like this:
select * from dbo.fx_function (SomeDateVariable)
My sql server fx_function recieves as a parameter datetime, my variable SomeDateVariable is datetime type.
I tried all different types of cast on @User :: SomeDateVariable but I either can't evaluate the expression or I have errors trying to execute the package.
Any ideas how the expression should look like?
I'll keep trying...

Group,
First let me say that I'm new to SSIS, so be gentle with me.
I need to extract a limited set of data from a very large view in Oracle (I know, yuk!). The view contains millions of rows, but I only need the child matches of 343 unique keys in a one to many relationship. In pure SQL the query would look something like this.
Select proj, tn, rn, total FROM Oracle.view WHERE proj in (select distinct proj from MSSQL.dbo.projlist)
As you can see, this is an impossible query on many levels.
My first thought was to get the runtime list into a variable and use that variable as a parameter in the Oracle OleDb Source. Alas, the Oracle source will not allow me to add a parameter.
My second thought was to use a script component and build a SQL_Command string into a variable with all of my keys included. Then use the read_write variable as the SQL Command from variable in the Oracle Source. My attempts to construct such a variable expression have failed.
Any ideas would be appreciated.

In the data flow task I have multiple OLE DB source task to retreive data from a cube using MDX. Below is an example of the query from sql command text field: I have a few questions on how to modify this statment to make it more robust.
1) The where clause [Calendar].[Quarter 2 (2007)] should actually be some kind of variable that will change each time
the user runs this project. So I am wondering how to make this a variable and get it into this field.
2) I had thought that I could use the SSIS variable. I have created one, but I can not figure how to get it into the field that
contains the given select statment.
3) I believe that once I get this variable part to work then I want a way to have user set this data value. Either by selecting data from a table in database or through a user interface where user enters data. I did do some resarch on creating a user interface, but I did not understand what I had to do, so if any one knows where to find a tutorial on how to do this let me know, or what they believe the best/easiest way is to get data from user to fill this where clause.
select * from OPENROWSET('MSOLAP', 'DATASOURCE=local; Initial Catalog=Patient Demographics 2005;',
'with member [Measures].[TimeDisplayName] as [Calendar].CurrentMember.Name
SELECT NON EMPTY { [Measures].[TimeDisplayName],[Measures].[Adjusted Relative Weight],[Measures].[Adjusted Case Weight]} ON COLUMNS,
({[Facility].[REGION].[NATCODE], [Facility].[REGION].[REGCODE]} *
[RIC].[CMGGRPCD].ALLMEMBERS) ON ROWS FROM [ESR]
WHERE [Calendar].[Quarter 2 (2007)]
')

I'm using following command to populate my OLE DB Source. I have two of those in each Data Flow in my package. One of the OLE DB Sources points to my source database the other to the destination. In order to limit the number of rows I use the WHERE clause below. The [EnergyMiserFSRLive] being the the name of the source database. The Connection manager points to the destination database.
I would like an elegant way to replace  [EnergyMiserFSRLive] with a parameter which I can reuse in each of my many data flows rather than use this hard coded value [EnergyMiserFSRLive].In particular I'm after the syntax of the below query that uses the parameter for [EnergyMiserFSRLive].
SELECT [SitesId]
     ,[SiteName]
     ,[FilePrefix]
     ,[City]
     ,[StateProv]
     ,[Country]
 FROM [Sites]
WHERE SitesId >= (SELECT MIN(SitesId) FROM [DBNameFSRLive].[dbo].[Sites])
 ORDER BY [SitesId]

Hello all,I'm writing a site with one page that uses the session variable (User ID) to pick one user ID out of a comma separated list in the field Faculty. The default parameterized query designed in the SqlDataSource wizard only returns lines that contain an exact match:SELECT * FROM tStudents WHERE ([faculty] = @faculty) The query: SELECT * FROM tStudents WHERE ([faculty] LIKE '%userID%') works as I need when I hard code the query with a specific user ID into the SqlDataSource in the aspx page. It will not work if I leave the @faculty parameter in it:SELECT * FROM tStudents WHERE ([faculty] LIKE '%@faculty%') e.Command.Parameters works to replace the @Faculty with a user ID, but again, adding the single quote and percentage sign either causes errors or returns no results. I've tried several variations of: string strEraiderID = "'%" + Session["eRaiderID"].ToString() + "%'"; e.Command.Parameters["@faculty"].Value = strEraiderID;no results are returned, not even the lines returned with the default select query.How do generate the equivalent of SELECT * FROM tStudents WHERE ([faculty] LIKE '%userID%') into the SqlDataSource? Thanks much!

The Variable name dropdown contains [User:viewName], so I select it. When I click OK to leave the edit dialog I get the error:
The variable User::viewName is required to be of type "VT_BSTR".
Only variables of type String occur in the Variable name dropdown; if I try changing it to a type other than string it doesn't occur in the dropdown. What is VT_BSTR and how can I change the variable type to it?
