Question

I’m storing large (varchar(max)) SQL scripts in a table. I’d like to execute the scripts in an SSIS package.

Looking at other posts on this site it’s easy enough to get the varchar(max) into an object variable. But then what to do? Is there a way for an Execute Sql Task (SQLSourceType of Variable) to specify an Object variable rather than a String variable?

Is there an approach that will work?

Answer 1

Here’s how I might approach it:

1. Add a Data Flow task to your control flow
   • Add a Source (ADO.NET) that connects to your database
   • Create a Package level Object variable (for the next step)
   • Add a Recordset destination that populates your data into the Object variable created in the previous step
2. Back on the control flow:
   • Create a package level String variable for the “current” query (see next step)
   • Add a For Each ADO.NET enumerator
     • Connect the previous Data Flow task to the For Each task
     • Configure the For Each to use the Object variable as a source, and to store the column index with the SQL into the String variable
   • Add an Execute SQL task inside the For Each task
     • Configure it to execute a SQL Command from Variable, and pick the string variable containing the current query

Basically it will collect the queries from the table, then for each collected query, assign it to a variable, and then the Execute SQL command can pull the command text from that variable.
