Level参考

Level	Action
0x0001	Dump pruning descriptor for each partitioned object
0x0002	Dump partition iterators
0x0004	Dump optimizer decisions about partition-wise joins
0x0008	Dump ROWID range scan pruning information

在9.0.1或者后面的版本,在level 2后还需要建立如下的表:

CREATE TABLE kkpap_pruning

            partition_count    NUMBER,

            iterator           VARCHAR2(32),

            partition_level      VARCHAR2(32),

              order_pt             VARCHAR2(12),

            call_time               VARCHAR2(12),

           part#               NUMBER,

            subp#              NUMBER,

            abs#               NUMBER

);
