Using Variable String In Sql Command
Dec 5, 1999
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

How do I use a @variable to hold on value return from an exec ('string command') statement.
Example for:
declare @OldID int
declare @cmd varchar(255)
declare @db varchar(25)
declare @OldOwner varchar(25)
set @db = 'DBNAME'
set @OldOwner = 'USERNAME'
select @cmd = 'select uid from ' + ltrim(rtrim(@db))'..sysusers where name = ' + "'" + ltrim(rtrim(@OldOwner)) + "'"
exec (@cmd)
How can I use @OldID to hold on UID return from this statement.
When I try use:
select @cmd = 'select @OldID = uid from ' + ltrim(rtrim(@db))'..sysusers where name = ' + "'" + ltrim(rtrim(@OldOwner)) + "'"
then I'm getting a error message: @OldID not declare.
Thanks.

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.

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.

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...

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?

Hello All
I m trying to update a table whose col name will be read from another table.
For e.g. Table1 gives the result:

Now in the second table, i need to update the table with Col name = 'Emp1' and then from the second row (above), I need to update Col name= 'Emp2'
I need to write one Update Statement which will handle all the cases. I tried
Update Table2 set @VariableName = .......
but didnt work...
How can i do that ?

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)]
')

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!

I'm looking at http://blogs.conchango.com/jamiethomson/archive/2007/03/13/SSIS_3A00_-Property-Paths-syntax.aspx and http://blogs.conchango.com/jamiethomson/archive/2005/10/11/SSIS_3A00_-How-to-pass-DateTime-parameters-to-a-package-via-dtexec.aspx trying to understand where we are at using datetime overrides in ssis from the command line. One of these articles suggests something has been fixed in ssis sp1, what part of this issue was fixed?
Can you override (from the command line) a user var in ssis whose ValueType property is datetime? Or do some of the older articles still apply, ie the user var must be string so that ssis wont create a separate user var with the same name etc etc? And if it is string, does some kind of conversion need to be done to compare it against datetime cols in t-sql inside the pkg?
I already know that the syntax is
dtexec /F Package.dtsx /SET Package.Variables[User::Var].Properties[Value];2007-01-02.
If this has been fixed, was it fixed in service pack 1, 2?

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.

I am using SQL 2005 and I'm trying to find a T-SQL command that will allow me to retrieve a sub string based on the token. For instance, if I had a string like this:
abc^defgh^ij^klmnop^qrs
Let assume the token is the ^ and I want to get the string at the third token klmnop.
is there a simple one line command that I can use to retrieve this data?

Is it possible to use a variable to specify the filegroup in the ALTER/CREATE PARTITION SCHEME command?
I want the partition scheme to use the default filegroup for ALTER and CREATE PARTITION SCHEME. At the time the script is created, I don't know the default filegroup in the database.
My code:
declare @fileGroupName VARCHAR(50) = (select top 1 name from
sys.filegroups where is_default = 1)
ALTER PARTITION SCHEME MyScheme NEXT USED @fileGroupName
Is failing:
Incorrect syntax near '@fileGroupName'.
Q: Is it possible to use a variable for the filegroup in the ALTER/CREATE commands? Is so, what is the correct syntax?
Q: If using a variable is not possible, is there another way to specify the default filegroup?

I have a string with values value1,value2, value3, value(n) which I would like to append to my table.
In the second column of my table I have a parameter which stays the same, so I end up with (if the parameter value is "123456")
Column 1 | Column 2
123456 | Value1
123456 | Value2
123456 | Value3
I would like to set up a single SQL statement which will process this regardless of the number of values (therefore rows) desired.
Something like:
INSERT INTO dbo_tblUserLevelApplicationRequests ( Column1, Column2) select EmployeeNumberParam as EmployeeNumber, ((stringofvalues) as valuestring)
Is it possible to do this with a single SQL statement?
