在 Squirrel 中创建/替换触发器

发布于 2024-10-05 04:58:32 字数 697 浏览 7 评论 0原文

我用的是松鼠3.2.0 当我尝试替换此触发器时：

CREATE OR REPLACE TRIGGER crw_ins_trig
  BEFORE INSERT OR UPDATE ON crew
  FOR EACH ROW
DECLARE

BEGIN
    if (:new.crw_id is null) then
        select crw_id_seq.nextval
        into :new.crw_id
        from dual;
    end if;  
END;
/

我收到消息“请输入参数值。‘:new’的值”

当我单击“确定”时，结果消息是：

Warning:   Warning: execution completed with warning
SQLState:  null
ErrorCode: 17110
Position: 27

Query 1 of 1, Rows read: 0, Elapsed time (seconds) - Total: 0.023, SQL query: 0.023, Building output: 0

在我的应用程序中，我收到错误 “ORA-04098:触发器“CRW_INS_TRIG”无效且重新验证失败”

这与 Squirrel 有关吗？如果是这样，我该如何解决这个问题？

I use squirrel 3.2.0
When I try to replace this trigger:

CREATE OR REPLACE TRIGGER crw_ins_trig
  BEFORE INSERT OR UPDATE ON crew
  FOR EACH ROW
DECLARE

BEGIN
    if (:new.crw_id is null) then
        select crw_id_seq.nextval
        into :new.crw_id
        from dual;
    end if;  
END;
/

I get the message "Please input the parameter values. Value for ':new'"

When I click OK the result message is:

Warning:   Warning: execution completed with warning
SQLState:  null
ErrorCode: 17110
Position: 27

Query 1 of 1, Rows read: 0, Elapsed time (seconds) - Total: 0.023, SQL query: 0.023, Building output: 0

In my application I get an error "ORA-04098: trigger 'CRW_INS_TRIG' is invalid and failed re-validation"

Does this has to do with Squirrel? If so, how can I solve this?

您应该在 SQuirrel 中卸载“sqlparam”插件，之后它不会要求您填写“:paramName”变量的值

您可能想在触发器中添加一个 REFERENCING 行，使其看起来像

CREATE OR REPLACE TRIGGER crw_ins_trig  
  BEFORE INSERT OR UPDATE ON crew  
  REFERENCING NEW AS NEW
              OLD AS OLD
  FOR EACH ROW  
BEGIN  
    if (:new.crw_id is null) then  
        select crw_id_seq.nextval  
        into :new.crw_id  
        from dual;  
    end if;    
END crw_ins_trig;

Try that。如果它不起作用，请尝试使用不同的工具（例如 SQL*Plus、PL/SQL Developer、Toad 等）执行该语句。

分享并享受。

You might want to add a REFERENCING line to your trigger so that it would look like

CREATE OR REPLACE TRIGGER crw_ins_trig  
  BEFORE INSERT OR UPDATE ON crew  
  REFERENCING NEW AS NEW
              OLD AS OLD
  FOR EACH ROW  
BEGIN  
    if (:new.crw_id is null) then  
        select crw_id_seq.nextval  
        into :new.crw_id  
        from dual;  
    end if;    
END crw_ins_trig;

Try that. If it doesn't work, try executing the statement using a different tool (e.g. SQL*Plus, PL/SQL Developer, Toad, etc).

Share and enjoy.
