I have an Execute SQL task which gives returns only one row with one column - a number. I set my result set to single row. Despite that, the task fails. Why ? How do I fix it ?
[Execute SQL Task] Error: There is an invalid number of result bindings returned for the
ResultSetType: "ResultSetType_Rowset".
Probably, you haven't configured your resultset parametrs correctly. To configure it, click on ResultSet in the Execute SQL Task, click Add. In the 'ResultSetName' column, enter the exact name of the columnname that you are retrieving or simply give it 0. In the 'variablename', select the variable you created to map the data returned.
In my case the ResultSet configured to "Full result set" when there were no results being returned. The Stored Procedure I was calling was simply deleting data. So I sat this to "None" and it worked..
