在10g/11g中如何查看SQL Profiles信息

在10g/11g中如何查看SQL Profiles的信息？  

在Oracle 10g中，可以查询以下的数据字段表来获取信息：  
SQLPROF$ATTR、SQLPROF$、SQLPROF$DESC  

在Oracle 11g中，上面的数据字典表被取而代之，可以访问下面的数据字段表来获取信息：  
SQLOBJ$、SQLOBJ$AUXDATA、SQLOBJ$DATA  

示例如下：  
Oracle 10g中：  
SQL> select attr_val from dba_sql_profiles a, sys.sqlprof$attr b   
  2  where a.signature = b.signature   
  3  and a.name='SYS_SQLPROF_0158d954d210000';   

ATTR_VAL  
-----------------------------------------------------��¶,͸¶-----------------------------------------------  
FULL(@"SEL$1" "T1"@"SEL$1")  
INDEX(@"SEL$1" "T2"@"SEL$1" ("T2"."OBJECT_ID"))  
LEADING(@"SEL$1" "T1"@"SEL$1" "T2"@"SEL$1")  
USE_NL(@"SEL$1" "T2"@"SEL$1")  

SQL> select object_name,object_type from dba_objects where object_Name like 'SQLPROF%';  

OBJECT_NAME                    OBJECT_TYPE  
------------------------------ -------------------  
SQLPROF$                       TABLE  
SQLPROF$ATTR                   TABLE  
SQLPROF$DESC                   TABLE  
SQLPROF_ATTR                   TYPE  
SQLPROF_ATTR                   SYNONYM  

这些表的创建语句可以从sql.bsq中获取。  

Oracle 11g中：  
SQL> select name from dba_sql_profiles;  

NAME  
------------------------------  
SYS_SQLPROF_0141d9f2f2a60001  
SYS_SQLPROF_0141d9e54d180000  

SQL> set autotrace on  
SQL> SELECT extractValue(value(h),'.') AS hint  
  2  FROM sys.sqlobj$data od, sys.sqlobj$ so,  
  3  table(xmlsequence(extract(xmltype(od.comp_data),'/outline_data/hint'))) h  
  4  WHERE so.name = 'SYS_SQLPROF_0141d9e54d180000'  
  5  AND so.signature = od.signature  
  6  AND so.category = od.category  
  7  AND so.obj_type = od.obj_type  
  8  AND so.plan_id = od.plan_id;  
   
HINT  
----------------------------------------------------------------------  
OPT_ESTIMATE(@"SEL$1", TABLE, "T1"@"SEL$1", SCALE_ROWS=0.01440028801)  
OPTIMIZER_FEATURES_ENABLE(default)  

SQL> select object_name,object_type from dba_objects where object_name like 'SQLOBJ%';  

OBJECT_NAME                    OBJECT_TYPE  
------------------------------ -------------------  
SQLOBJ$                        TABLE  
SQLOBJ$AUXDATA                 TABLE  
SQLOBJ$DATA                    TABLE  
SQLOBJ$DATA_PKEY               INDEX  
SQLOBJ$_PKEY                   INDEX  

在Oracle 11g中，这些创建表的语句被从sql.bsq中剥离了出来，在11g中，被剥离到了dmanage.bsq中，并通过sql.bsq中调用来进行表的创建。  
$cat $ORACLE_HOME/rdbms/admin/sql.bsq
