Here is the output after adding the set option:įirst of all we should remember that default value of the setting is OFF, which is actually good. To avoid the warning we can use “set ansi_warnings off” before the script. SELECT AVG ( Qty ) 'Avg' FROM WHERE ID IN ( 1, 2 )Īs the error says, NULLs are being ignored because we are using aggregate function (SUM, AVG). Warning: Null value is eliminated by an aggregate or other SET operation. SELECT SUM ( Price ) 'Sum - 2' FROM WHERE ID IN ( 1, 3 ) SELECT SUM ( Qty ) 'Sum - 1' FROM WHERE ID IN ( 1, 3 ) INSERT INTO ( ID, Qty, Price ) SELECT 3, 5, NULL INSERT INTO ( ID, Qty, Price ) SELECT 2, NULL, 200 INSERT INTO ( ID, Qty, Price ) SELECT 1, 25, 100 Let us run below script in SQL Server Management Studio to see the effect.ĭECLARE TABLE ( ID INT, Qty INT, Price MONEY ) Warning: Null value is eliminated by an aggregate or other SET operation Let’s look at the various warnings which can be suppressed when working with NULL. In future blogs, I would try to explain another one called ANSI_WARNINGS.
