In one of his posts on Microsoft’s SSIS Team Blog, he references the source of this idea as being […] “Updating Type 2 SCD Attributes using the T-SQL Merge Statement”

Updating Type 6 Slowly Changing Dimension Attributes

This post completes my mini-series on implementing the Kimball-based SSIS patterns described by John Welch in his SQLBits session on Handling Advanced Data Warehouse Scenarios in SSIS.

The task here is how to best implement inserts and updates to slowly changing dimensions with Type 6 […] “Updating Type 6 Slowly Changing Dimension Attributes”
