Problem IC72120
|
Status: Closed |
EXPLAIN OF FEDERATED QUERY INDICATES PREDICATE APPLIED TO WRONG OR NON-EXISTENT OPERATOR |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
A predicate may not show up in the explain output (db2exfmt,
Visual Explain, Optimum Query Tuner), or it may be associated
with the wrong operator, when a query against a remote table is
explained, and that query includes a predicate against that
remote table.
You are experiencing this problem if the following query returns
a non-zero count:
select count(*) from explain_predicate where operator_id >
(select max(operator_id) from explain_operator)
You are also experiencing this problem if a local predicate is
applied to an operator that does not contain the columns
associated with that predicate. |
