Oracle --获取绑定变量的值.

SELECT * FROM DBA_HIST_SQLBIND WHERE SNAP_ID>67073 AND SNAP_ID<=67079 AND SQL_ID='3DR3410F086P4';
SELECT * FROM v$sql_bind_capture where sql_id=''

http://blog.itpub.net/22034023/viewspace-689802/

通过v$sql_bind_capture视图，可以查看绑定变量，但是这个视图不太给力，只能捕获最后一次记录的绑定变量值。

而且两次捕获的间隔有一个隐含参数控制。默认是900秒，才会重新开始捕获。在900内，绑定变量值的改变不会反应在这个视图中。

10G以后可以通过如下方法查看AWR报告里记录的SQL的绑定变量值。

select snap_id, name, position, value_string,last_captured,WAS_CAPTURED  from dba_hist_sqlbind  where sql_id = '576c1s91gua19' and snap_id='20433';

----------SNAP_ID就是AWR报告的快照ID。

----------name,绑定变量的名称

----------position，绑定值在SQL语句中的位置，以1，2，3进行标注

---------value_string ，就是绑定变量值

---------,last_captured，最后捕获到的时间

--------- WAS_CAPTURED，是否绑定被捕获，where子句前面的绑定不进行捕获。

dba_hist_sqlbind视图强大的地方在于，它记录了每个AWR报告里的SQL的绑定变量值，当然这个绑定变量值也是AWR生成的时候从v$sql_bind_capture采样获得的。

通过这个视图，我们能够获得比较多的绑定变量值，对于我们排查问题，这些值一般足够了。

还有一个需要注意的地方是，这两个视图中记录的绑定变量只对where条件后面的绑定进行捕获，这点需要使用的时候注意。(备注 11G已经修复了这个问题.)

below from http://xanpires.wordpress.com/2012/05/20/vsql_bind_capture-and-dba_hist_sqlbind-view/

Starting from Oracle 10g, bind variables are periodically captured in the v$sql_bind_capture and dba_hist_sqlbind views
(keep in mind a Diagnostics Pack license is required for accessing dba_hist_* views).

Bind variables are captured either when a query is hard parsed; or if the last capture was _cursor_bind_capture_interval seconds ago (default 900).

See V$SQL_PLAN.OTHER_XML for those used at parse time. Also DBA_HIST_SQL_PLAN.OTHER_XML.

You could trace your session using event 10046 at level 12 and see the resulting trace file.

You could get them from real time sql monitoring via V$SQL_MONITOR.BINDS_XML.

They are captured periodically in V$SQL_BIND_CAPTURE and and stored in the repository DBA_HIST_SQLBIND.

And there are probably some other ways as well.

So, in terms of AWR, DBA_HIST_SQL_PLAN and DBA_HIST_SQLBIND should be of use.

——-
Bind values can be found together with other info in column OTHER_XML in V$SQL_PLAN or DBA_HIST_SQLPLAN in row with ID=0.
They can by displayed (if available) with the option ADVANCED from

V$SQL_PLAN:
select * from table(dbms_xplan.display_cursor('&SQL_ID',&child,'ADVANCED'));

AWR:
select * from table(dbms_xplan.display_awr('&SQL_ID',NULL,NULL,'ADVANCED'));
