Yes – the create_sql_profile.sql script in the write-up utilizes the hints saved inside the other_xml area of v$sql_plan to produce a SQL Profile that usually forces a press release to use the approach from which the hints were extracted.

Laptop science is very intriguing topic, theoretical knowledge of information processing and computation and sensible familiarity with implementation in Pc program. The subject Laptop science has vast place and it really is The most career oriented topic together with lots of sub fields.
