By re-generating the execution plan, the execution plan deviation of Bound variables will be solved, resulting in the SQL Execution time being too long. The execution plan SQLSome SQL statements in the 11G environment of the Basic Elements (time, user, and problem) are very inefficient in the program, but they are very fast in plsql. by viewing the execution
