ORACLE 查询SQL执行时间：

SELECT

C.sample_time 执行时间,

A.ELAPSED_TIME_DELTA / 1000000 "执行耗时(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'/*用户名(大写)*/ AND C.sample_time IS NOT NULL

ORDER BY C.sample_time DESC;

或者

SELECT A.sql_ID,B.begin_interval_time 执行时间,B.startup_time,

A.elapsed_time_delta/1000000 "执行耗时(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'/*用户名(大写)*/

ORDER BY begin_interval_time DESC;

结果如下：
