ORACLE 查詢SQL執行時間

ORACLE 查詢SQL執行時間：

SELECT 
C.sample_time 執行時間,
A.ELAPSED_TIME_DELTA / 1000000 "執行耗時(S)",
B.sql_text SQL文本,
to_char(SUBSTR(B.sql_text,1,400))  SQL文本截取
FROM dba_hist_sqlstat A
LEFT JOIN dba_hist_sqltext B ON A.sql_id = B.sql_id
LEFT JOIN dba_hist_active_sess_history C ON C.sql_id = B.sql_id
WHERE PARSING_SCHEMA_NAME= 'SCOTT'/*用戶名（大寫）*/ AND C.sample_time IS NOT NULL
ORDER BY C.sample_time DESC;

或者

SELECT A.sql_ID,B.begin_interval_time 執行時間,B.startup_time,
A.elapsed_time_delta/1000000 "執行耗時(S)", 
T3.sql_text SQL文本,
to_char(SUBSTR(T3.sql_text,1,400))  SQL文本截取
FROM dba_hist_sqlstat A
LEFT JOIN DBA_HIST_SNAPSHOT B ON A.snap_id = B.snap_id 
LEFT JOIN dba_hist_sqltext T3 ON A.sql_id = T3.sql_id
WHERE PARSING_SCHEMA_NAME= 'SCOTT'/*用戶名（大寫）*/
ORDER BY begin_interval_time DESC;

結果如下：
