I am getting the following warning when importing data into SQL server using SSIS:
Warning: 0x80047076 at Data Flow Task, SSIS.Pipeline: The output column "Copy of Column 0" (3288) on output "Data Conversion Output" (2936) and component "Data Conversion 2" (2934) is not subsequently used in the Data Flow task. Removing this unused output column can increase Data Flow task performance.
The problem is that I do not have a column whose output alias is named "Copy of Column 0". I have no idea where this warning is coming from, or how to get rid of it.
Thanks
