DB2 SQL-Error: -415
SQLState: 42825
Short Description: THE CORRESPONDING COLUMNS OF THE OPERANDS OF A UNION OR A UNION ALL DO NOT HAVE COMPARABLE COLUMN DESCRIPTIONS C
The column descriptions of corresponding columns of the operands of a UNION or UNION ALL must be comparable. The columns of ordinality 'column-number' of the operands in this UNION or UNION ALL do not satisfy this requirement. For columns to be comparable, they must both be either numeric, character, graphic, date, time, or timestamp. They cannot be a mixture of these groups. If corresponding columns have field procedures, they must both have the same field procedure. System action: The statement cannot be executed. Programmer response: Check the data types of the specified columns and correct the UNION or UNION ALL statement so that all corresponding columns have comparable column descriptions.
