Question

我使用squirrel 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。值为'：new'”

单击“确定”后，结果消息为：

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: trigger 'CRW_INS_TRIG' is invalid and failed re-validation"

这与Squirrel有关吗？如果是这样，我该如何解决？

Answer 1

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

Answer 2

您可能希望在触发器中添加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;

试试吧。如果它不起作用，请尝试使用其他工具（例如SQL * Plus，PL / SQL Developer，Toad等）执行该语句。
