  • SSIS Design Pattern - Read a DataSet From Variable In a Script Task

    Introduction One of the things I appreciate about SSIS is the script elements. There is a lot of functionality built into the engine out of the box but I like the idea of having a Script Task on the Control Flow and a Script Component on the Data Flow just in case.

It's used in Data Warehousing, but increasingly data is being staged in SQL Server for non-Business-Intelligence purposes.   Maintaining data integrity is key when loading data into any database. A common way of accomplishing this is to ...
