Description

statement_performance_analyzer is a stored procedure available with the Sys Schema which returns a report on running statements.

The following options from the sys_config table impact the output:

• statement_performance_analyzer.limit - maximum number of rows (default 100) returned for views that have no built-in limit.
• statement_performance_analyzer.view - custom query/view to be used (default NULL). If the statement_performance_analyzer.limit configuration option is greater than 0, there can't be a LIMIT clause in the query/view definition

If the debug option is set (default OFF), the procedure will also produce debugging output.
