如何插入nextval触发for循环内部 [英] How to insert nextval to trigger inside for loop

问题描述

这里是触发器的代码，它有一个for循环.触发触发器(INSERT或UPDATE)时，必须有另一个表数据包括MICL_SUP

Here is a code for trigger and it have a for loop. When trigger is fired (INSERT OR UPDATE) there's another table data must include it is MICL_SUP

 OPEN  projMgrsCursor;
        LOOP
        FETCH projMgrsCursor INTO projMgr;  
        select micl_sup_id_seq.nextval into  SUPID from dual;
        insert into MICL_SUP VALUES ((SUPID), (SELECT SYSDATE FROM DUAL),                             :NEW.ENTRYADDEDBY_EMP_NO, 3000, 0,projMgr, NULL,:NEW.EMP_NO);
       END LOOP;    

      CLOSE projMgrsCursor;

这是表结构. Sup_ID主键和唯一键.我无法对表结构进行任何更改

This is the table structure. Sup_ID primary and unique key . I can't make any changes to table structure

SUP_ID  -primary key             
ASSIGNED_DATE            
ASSIGNED_BY_EMP_NO          
AMOUNT_LIMIT            
IS_OVVERRIDDEN      
SUP_EMP_NO          
RTD_EMP     
EMP_NO  

要输入sup_ID，请使用select micl_sup_id_seq.nextval into SUPID from dual; 但是，当我运行此代码时，出现错误"RA-00001: unique constraint violated"(这不是编译错误)还有其他方法可以添加sup_ID吗?我在哪里弄错了?

To enter sup_ID I use select micl_sup_id_seq.nextval into SUPID from dual; but when I run this code there's an error "RA-00001: unique constraint violated" (this is not a compilation error ) Is there any other way to add sup_ID? Where have I gone wrong?

此问题与此触发器 PlSQL触发器错误ORA-0000 ORA- 06512:

推荐答案

为什么不将micl_sup_id_seq.nextval的计算包括到光标中?

Why not including calculation of micl_sup_id_seq.nextval into your cursor?

cursor  projMgrsCursor is 
  select b.BU_MEMBER_ID, micl_sup_id_seq.nextval SUPID
  from ...
