sql语句，参数,变量=@count output 例： declare @exec_sqlCount nvarchar(1000) declare @count int set @exec_sqlCount= ‘select @count=sum(t.a) from t ‘ declare @scon nvarchar(100)=‘@count int output‘ --定义一个输出参数execute sp_executesql @exec_sqlCount,@scon,@count=@count output --执行 --很多时候查询的时候不能将查到的值带出，所已可用该方法。。 动态的调用输出查询语句中的值 execute sp_ex...
一个SQL，通过SPM固定它的执行计划，可以通过DBMS_SPM.LOAD_PLANS_FROM_CURSOR_CACHE实现。也可以通地此功能在不修改原SQL的情况下对其加HINT来固定执行计划。DB VERSION:Oracle 11.2.0.4OS:CentOS 6.6例如：原SQL走索引：SELECT * FROM SCOTT.TB_SPM WHERE OBJECT_ID=10;想通过加HINT让其走全表扫描：SELECT /*+FULL(TB_SPM)*/* FROM SCOTT.TB_SPM WHERE OBJECT_ID=10;在V$SQL中查询出，原SQL的SQL_ID=064qcdmgt6thw，加HINT的SQL...
