The values of the execute_time and get_plan_time fields in the gv$sql_audit view are optimized.
The ASIN() and ACOS() functions are supported in MySQL-compatible mode.

Garbled characters are generated at the client during the conversion of character sets of the LOB type columns when row records are returned.
If the EXISTS subquery contains NULL or COUNT(*), the result set is incorrect.
The SQL execution plan fails to hit the plan cache because of the sensitive matching of sorting rules.
