格式化v$sql_plan查看实际执行计划

1、先去v$session_longops查看正在执行的6秒以上的session

SELECT * FROM V$SESSION_LONGOPS t WHERE sofar<> totalwork --未执行完的;

2、通过以下sql对实际执行过的执行计划进行格式化

SELECT LPAD(' ', 2 * (LEVEL - 1)) || OPERATION || ' ' ||

DECODE(ID, 0, 'Cost = ' || POSITION) "OPERATION",

OPTIONS,

OBJECT_NAME,

COST,

CARDINALITY,

CPU_COST,

IO_COST/*,

ACCESS_PREDICATES,

FILTER_PREDICATES*/

FROM V$SQL_PLAN

START WITH (ADDRESS = '0000000459AE0110' AND HASH_VALUE = 2236084057

/*and child_number = :child*/

AND ID = 0)

CONNECT BY PRIOR ID = PARENT_ID

AND PRIOR ADDRESS = ADDRESS

AND PRIOR HASH_VALUE = HASH_VALUE

AND PRIOR CHILD_NUMBER = CHILD_NUMBER

ORDER BY ID, POSITION;
