1 dba_hist_sql_plan 基本就这么个用法,查询的字段呢,和你印象中执行计划基本一样。 select SQL_ID, PLAN_HASH_VALUE, ID, OPERATION, OBJECT_OWNER, OBJECT_NAME, DEPTH, COST, TIMESTAMP from dba_hist_sql_plan where sql_id = 'sd5f7z54yn623' and TIMESTAMP >= date '2023-07-01' and TIMESTA...
AWR会定时把动态性能视图中的执行计划保存到dba_hist_sql_plan视图中,如果你想要查看历史执行计划,可以采用如下方法查询: select * from table(dbms_xplan.display_awr('sql_id'); 4. 在用sqlplus做SQL开发是(Autotrace) set autotrace是sqlplus工具的一个功能,只能在通过sqlplus连接的session中使用,它非常适合在...
whereupper(sql_text) like 'SELECT * FROM TEST%'; SQL>select * fromtable(dbms_xplan.display_awr('&sql_id')); --注: 1.DISPLAY_AWR 函数显示存储在AWR历史数据的执行计划。 2.须对以下视图有SELECT权限:DBA_HIST_SQL_PLAN 和DBA_HIST_SQLTEXT。
1. 查询v$sql_plan: 使用SQL语句查询v$sql_plan表，通过设置SQL_ID和计划哈希值参数来获取特定SQL语句的执行计划，注意SQL_ID可通过v$sqltext和dba_hist_sqltext查询，或通过其他途径获取。2. 通过包DBMS_XPLAN：使用此包提供多种展示执行计划的方式，如DISPLAY、DISPLAY_CURSOR、DISPLAY_AWR、DISPLAY_...
