The tool db2exfmt formats the contents of the EXPLAIN tables. This tool is in the misc subdirectory of the instance sqllib directory. This tool uses the statistics from the EXPLAIN snapshot, if the snapshot is available. The db2expln tool describes the access plan selected for SQL and XQuery statements. Use the tool to obtain a quick explanation of the chosen access plan when explain data was not captured. For static SQL and XQuery statements, db2expln examines the packages stored in the system catalog tables. For dynamic SQL and XQuery statements, db2expln examines the query cache sections.
