SQL Stored Procedure: If variable is not null, update statement

Question

I have an update statement in a stored procedure that looks generally like this:

Update [TABLE_NAME]
Set XYZ=@ABC

Is there a good way to only t

Answer 1

Another approach when you have many updates would be to use COALESCE:

UPDATE [DATABASE].[dbo].[TABLE_NAME]
SET    
    [ABC]  = COALESCE(@ABC, [ABC]),
    [ABCD] = COALESCE(@ABCD, [ABCD])
