The IN XML option returns the EXPLAIN text as XML text rather than as plain English text. See XML Documents Produced by the Query Logging XMLPLAN Option for the XML plan attributes and the XML schema used by the XML output produced by the IN XML option.
The EXPLAIN IN XML request modifier can also specify that the output be returned in one of two possible formats:
- As XML text with any associated DDL text. You specify this with the IN XML option.
- As XML text, but without any associated DDL text. You specify this with the IN XML NODDLTEXT option.
A complementary option for the BEGIN QUERY LOGGING and REPLACE QUERY LOGGING statements optionally creates a compact XML version of the information that can be stored in a DBQL table.
