Question

我在Oracle 11g数据库中运行的查询很少，这些查询是可重复的查询。我想查找基于sql_id或sql_text执行每天执行所花费的日期和时间的次数？有没有办法找到这个？

执行次数在AWR报告中。这意味着它也可能来自DBA_HIST_表，但我不知道哪一个。根据您之前的问题，我假设您已获得AWR许可。

--Find the SQL_ID.  If not in shared_pool it should be in a historical table.
select * from v$sql where sql_fulltext like ...;
select * from dba_hist_sqltext where sql_text like ...;

--Find the begin and end snapshot periods.
--Be careful here, I've seen some weird timezone issues, it can be annoyingly
--difficult to get the exact period of time you want.
select * from dba_hist_snapshot order by begin_interval_time desc;

--Get AWR report.
select dbms_workload_repository.awr_sql_report_text(l_dbid => 3037785498
  , l_inst_num => 1, l_bid => 53007, l_eid => 53020, l_sqlid => '57pfs5p8xc07w')
from dual;
