declare l_depnam varchar2(20) := 'testing'; l_loc varchar2(10) := 'Dubai'; begin execute immediate 'insert into dept values (:1, :2, :3)' using 50, l_depnam, l_loc; commit; end;
3. 从动态语句检索值(INTO子句)
declare l_cnt varchar2(20); begin execute immediate 'select count(1) from emp' into l_cnt; dbms_output.put_line(l_cnt); end;
4. 动态调用例程.例程中用到的绑定变量参数必须指定参数类型.黓认为IN类型,其它类型必须显式指定
declare l_routin varchar2(100) := 'gen2161.get_rowcnt'; l_tblnam varchar2(20) := 'emp'; l_cnt number; l_status varchar2(200); begin execute immediate 'begin ' l_routin '(:2, :3, :4); end;' using in l_tblnam, out l_cnt, in out l_status;
if l_status != 'OK' then dbms_output.put_line('error'); end if; end;
5. 将返回值传递到PL/SQL记录类型;同样也可用%rowtype变量
declare type empdtlrec is record (empno number(4), ename varchar2(20), deptno number(2)); empdtl empdtlrec; begin execute immediate 'select empno, ename, deptno ' 'from emp where empno = 7934' into empdtl; end;
