| Produkt: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problembeschreibung: |
This problem could happen when a correlation context (e.g., a
bind-in host variable value,
like the xmldoc in a query) is being reversed TQed multiple
times. In other words
the problem is caused by a faulty execution plan which is
sharing a data buffer
across operators in different subsections
