The QryLogExplainV view is populated if the WITH EXPLAIN option is requested in addition to the information row.
Because the explain can be larger than 31,000 characters, it may use multiple rows to hold the data.
Referenced Columns
Many of the Data Dictionary view columns have referenced table columns. That is, the value in the view column corresponds to a value in the selected column referenced in the table. It would be meaningful to join the view and the referenced table based on the selected column and the referenced column.
Referenced columns for this view are:
| View Column | Description |
|---|---|
