I) 使用Explain Plan,查询PLAN_TABLE;
EXPLAIN PLAN
SET STATEMENT_ID='QUERY1'
FOR
SELECT *
FROM a
WHERE aa=1;
SELECT operation, options, object_name, object_type, ID, parent_id
FROM plan_table
WHERE STATEMENT_ID = 'QUERY1'
ORDER BY ID;
EXPLAIN PLAN
SET STATEMENT_ID='QUERY1'
FOR
SELECT *
FROM a
WHERE aa=1;
SELECT operation, options, object_name, object_type, ID, parent_id
FROM plan_table
WHERE STATEMENT_ID = 'QUERY1'
ORDER BY ID;
II)SQLPLUS中的SET TRACE 即可看到Execution Plan Statistics
SET AUTOTRACE ON;
