如何验证SQL PROFILE的性能?(3)

　　| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time |

　　----------------------------------------------------------------------------------

　　| 0 | SELECT STATEMENT | | 1 | 113 | 408 (1)| 00:00:01 |

　　|* 1 | TABLE ACCESS FULL| PROFILE_TEST | 1 | 113 | 408 (1)| 00:00:01 |

　　----------------------------------------------------------------------------------

　　Predicate Information (identified by operation id):

　　---------------------------------------------------

　　1 - filter("OBJECT_ID"=5060)

　　Statistics

　　----------------------------------------------------------

　　1 recursive calls

　　0 db block gets

　　1471 consistent gets

　　0 physical reads

　　0 redo size

　　1779 bytes sent via SQL*Net to client

　　543 bytes received via SQL*Net from client

　　2 SQL*Net roundtrips to/from client

　　0 sorts (memory)

　　0 sorts (disk)

　　1 rows processed

　　以上我们通过sqltune_category将SQL PROFILE的作用域限定在session级别，实现了对SQL PROFILE的性能测试。
