The QryLogExplain[V] view is populated if the WITH EXPLAIN option is requested in addition to the information row. The following table describes the fields in QryLogExplain[V].

 

QryLogExplain[V] Field

Description

CollectTimestamp

Time that the rows were written to the database. This field is also part of the multicolumn NUPI (also see ProcID).

ExplainText

Full Explain text segment.

The text is not formatted and appears as a single long string. You may need to program a parsing application to look at the text.

ExpRowNo

Used if Explain text is greater than 31,000 characters and the system generates multiple rows.

ProcID

Unique processor ID of the Dispatcher and part of the multi-column NUPI (also see CollectTimeStamp).

QueryID

Internally generated identifier of the query and the FK to other DBQL tables.

Note: QueryID is a system-wide unique field; You can use QueryID to join DBQL tables or the DBC.TdwmExceptionLog table with DBQL tables without needing ProcID as an additional join field.
