下面看下oracle游标的简易用法,具体代码如下所示:
create or replace procedure nw_delyw(ioperation_id number, suserid varchar2) is scurdjbh yw_operation_link.djbh%type; cursor table_yw(ywid yw_operation.id%type) is select * from yw_operation_link t1 where t1.operation_id = ywid; begin for dr in table_yw(ioperation_id) loop scurdjbh := dr.djbh; --取得opercationid /* select t1.operation_id into soperationid from yw_operation_link t1 where t1.djbh = scurdjbh;*/ --写日志 insert into log_zfywinfo (djbh, djdl, djxl, dlmc, xlmc, slr, slrid, sqrxm, fwzl, zfrq, zfrid, zfr) select distinct scurdjbh, t4.id, t3.id, t4.name, t3.name, t1.slry, t1.slryid, t1.sqrxm, t1.zl, sysdate, suserid, (select tt.name from pw_user tt where tt.id=suserid) from yw_operation t1 join yw_operation_link t2 on t2.operation_id = t1.id join business_type t3 on t3.id = t1.business_id join business_class t4 on t4.id = t3.parent_id where t1.id = dr.operation_id; exception when others then rollback; dbms_output.put_line(sqlerrm); end nw_delyw;
oracle使用cursor 游标循环添加删除更新。

oracle游标简单示例
使用游标打印员工姓名和薪水
set serveroutput on; declare cursor cemp is select ename,sal from emp; cname emp.ename%type; csal emp.sal%type; begin open cemp; loop fetch cemp into cname,csal; exit when cemp%notfound; dbms_output.put_line(cname || '的薪水是' || csal); end loop; end; /
带参数的游标
使用游标打印某部门号的所有员工姓名
set serveroutput on; declare cursor cemp(cno emp.deptno%type) is select ename from emp where emp.deptno = cno; cname emp.ename%type; begin open cemp(10); loop fetch cemp into cname; exit when cemp%notfound; dbms_output.put_line(cname); end loop; end; /
