SQL Server Data Validation Examples: Null Rates, Value Thresholds, and Table Schema or Data Diffs
This video walks you through 5 powerful advanced data validation test case examples. These table-level tests cover thresholds for column null rates and value frequencies observed. These tests also covering monitoring table structure and table data changes.
You can refactor and re-use the samples in your projects. The scripts in the demo are all out on Github along with 66 total sample validation tests along with a basic and an advanced script for automating the tests.
