The SQL Queries will Remain the SAME , only SOME of the Tables will be paritioned into different tablespaces
We have found our application SQL Queries to work well with RULE , Hence the Creation of the Outlines done in RULE . But after paritioning since SQL Queries on the PARTITONED Tables will run Only on "COST" we will USE the Outlines so Created Earlier Unless you mean to keep the Optimizer_mode=RULE even after partitioning to make the optimizer jump back & forth between RULE & COST (depending on whether NON-partitioned Or Partitioned Table is Accessed in the SQL ) Thanks -----Original Message----- Sent: Wednesday, November 27, 2002 3:36 PM To: VIVEK_SHARMA; LazyDBA.com Discussion 1. Optimizer must be CBO. 2. outlines are based on a Query Example: if you create an outline called AXZ for SELECT ename FROM emp; The outline AXZ will be used *if only if*, you query is exactly as "SELECT ename FROM emp;" Note: CBO is sensitiv to cases, blank space etc... so if you type "sElect ENAME from EMP;"...do NOT be supprised to see your plan not showing up..
