ORA-01037: Cause: An attempt was made to process a complex SQL statement which consumed all available memory of the cursor.Action: Simplify the complex SQL statement. Alternatively, you can use the NO_EXPAND hint which prevents the cost-based optimizer from considering OR-expansion for queries having OR conditions or INLISTS in the WHERE clause. Usually, the optimizer considers using OR expansion and uses this method if it decides the cost is lower than not using it. Refer to Oracle8i Designing and Tuning for Performance for information about using hints.(It's not a OCP question)

另外，可否把你考ＯＣＰ的感想整理整理，让大家分享一下，学习一下。毕竟OCP还是较难考的，也让很多人向往，我也想考，但又不了解......
