This article mainly tells you the actual operation process of correctly updating the execution plan in the DB2 database. Like the Oracle database, the analytics of your SQL in DB2 also uses the optimizer, generate an Access Plan ). The DB2 optimizer is actually a set of standard rules. Generally, we only need to tell DB2 what to search, not how to search.
So what is the DB2 optimizer used to determine the optimal SQL access path?
