WL#944: More information in slow query log
Status: Un-Assigned — Priority: Medium
It would be very helpful to have additional information about slow queries, in slow query logs, which sometimes can't be delivered from explain: - disk based tmp table - merge (file) sort We know this only after query execution. Other useful might be (they can be delivered from explain) - full join - full table scan So the event may look like this: # Time: 030603 16:45:27 # User@Host: pz[pz] @ localhost  # Query_time: 0 Lock_time: 0 Rows_sent: 100000 Rows_examined: 100000 # Execution flags: full_join,table_scan,merge_sort use test; SELECT * FROM A,B order by A.id;
