SQL Server Data Validation Examples: Numeric and Date Fields

This video walks you through 11 standard data validation test case examples. The numeric validation tests check for nulls, negative numbers, inside a specific range, in a list, not in a list, and comparing multiple numeric fields or doing calculations. The date validation tests check for nulls, dates inside a range, make sure there is or is not a time part, and comparing multipe date fields. There is also a bonus tip showing how to handle date overlaps when joining tables...ensuring that table#1 start/end dates overlaps table#2 start/end dates when you pull them together in a join.

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.
