Example: CASE Expression Fails - Advanced SQL Engine - Teradata Database

In the following statement, the CASE expression fails when column_2 contains the value 1 and column_3 contains the value 11223344556677889900.12 because the result is a DECIMAL value that requires more than 38 digits of precision:

   SELECT SUM (CASE
                WHEN column_2=1 
                THEN column_3 * 6.112233445566778800000
                ELSE column_3
               END )
   FROM dec22;
