SQL Server Transact Basic to Expert - Returning Non NULL value of a string
 

This blog shows how to get the First Non Null Value from a list of expression using COALESCE function in SQL

Example:

DECLARE @Val1 int
DECLARE @Val2 int
DECLARE @Val3 int

SET @Val2 = 101
SET @Val3 = 102

SELECT COALESCE(@Val1 , @Val2 , @Val3 )

The expected result would be 101
