I am trying to use a variable as an input in an 'Execute SQL Task'.
I pre-set my object outside the ForEach container. In the foreach container I set up all the Variable Mappings. I know all that is done correctly because when I use a Script Task to output these parameters to the screan it works.
But when I set up my 'Execute SQL Task' with one of these variables in the Variable Mappings as 'Input', with Parameter Name set to 0, and then have this simple script in the SQLStatement:
SELECT NAME FROM SCHDTASK
WHERE ID = ? --@Task_ID
I get an error when I run this.
"[Execute SQL Task] Error: Executing the query "SELECT NAME FROM SCHDTASK WHERE ID = ?" failed with the following error: "Syntax error, permission violation, or other nonspecific error". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
If anyone has any idea what I am doing wrong here, I would really appreciate any kind of input.
Thank you!

I don't use SSIS so I have no clue but let my post serve as a "bump" to someone who may. 🙂

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

What are the datatypes of the variables?

The variable is an integer.

Looks like I figured it out though:

For 'Parameter Size' I put in 1 before. Now changed it to 3 and it works. No clue what exactly did it.

Thanks.

According to BOL, the parameter size is used for the following:

Parameter Size
Provide the size of parameters that have variable length, such as strings and binary fields.
This setting ensures that the provider allocates sufficient space for variable-length parameter values.

Usually I set this to -1.
