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 trigger the update statement if the variable is not null or the value -1?

Similar to an IF NOT EXISTS...INSERT question.

Thank you so much.

Use a T-SQL IF:

IF @ABC IS NOT NULL AND @ABC != -1
    UPDATE [TABLE_NAME] SET XYZ=@ABC

Take a look at the MSDN docs.
