* Created SSIS Package that includes a ForLoop Container.
* I've set the following
InitExpression - @count = 118
EvalExpression - @Increment <= @count
AssignExpression - @Increment = @Increment + 1
* Package runs successfully without issue
* I want to change the InitExpression to not be a hard coded value but to be a count from a DB table....example below.
* select count(*) from msdb..reports where report_type = 'Errors' and report_status = 0
* Any help anyone can provide?

Use an EXEC SQL task to fill the count variable and you should be able to leave the init express alone.

Thank you for the response.

I'm assuming you mean a SSIS SQL Task, correct?

Should it go inside or outside the For Loop? Trying to place it outside I can't see the @count parameter.

Inside causes other problems.

What did you end up doing, Glenn?

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.

As Elliott suggested I created an EXEC SQL Task to set the @count variable value.

I had to do it outside the ForEach Loop and originally couldn't see the variable there. I dropped it and recreated with the scope as a package scope and not ForEach scope. Tested and all works as expected.
