This procedure reads the specified request log and populates the global temporary table satmp_request_time with the statements
from the log and their execution times.
For statements such as inserts and updates, the execution time is straightforward. For queries, the time is calculated from
preparing the statement to dropping it, including describing it, opening a cursor, fetching rows, and closing the cursor.
For most queries, this is an accurate reflection of the amount of time taken. When the cursor is left open while other events
take place, such as operator interaction or client processing, the time appears as a large value but is not a true indication
that the query is costly.
This procedure recognizes host variables in the request log and populates the global temporary table satmp_request_hostvar
with their values. For older databases where this temporary table does not exist, host variable values are ignored.
If you do not specify a log file, the default is the current log file that is specified in the command with -zo, or that has
been specified by
sa_server_option( 'RequestLogFile', filename )
If a connection ID is specified, it is used to filter information from the log so that only requests for that connection are
