-901 WHILE COMPILING A STATEMENT |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / A10 - DB2 |
| Problembeschreibung: |
Under rare scenarios, DB2 can trap when compiling a SQL
statement if the following conditions are true:
1. The SQL statement has at least 2 joins.
2. The SQL statement has an equality join predicate. Assume one
of the columns that participate in the join predicate is T1.C1.
and Table T1 has a generated column that is generated based on
C1.
3. The generated column is not referenced in the SQL statement
Possible stack is:
