Problembeschreibung: | |
Instance may abend during execution of a query that contains a NULL constant equated with an atomic (non-function) expression. Specifically, following conditions need to occur for such a scenario: - Query contains at least 2 relational operator (RELOP) predicates - Both RELOPs need to be equality predicates - The NULL constant is used in both RELOPs - The other expressions used in both RELOPs are also atomic expressions - The data types of the other 2 expressions are incompatible | |

Local-Fix: | |
Ensure that the query is well-formed, since a query which has a NULL constant equated to anything will typically always be a false query, i.e., such a query will always return zero records. | |
