我有从表格创建的视图:
CREATE OR REPLACE VIEW employee_list AS
SELECT firstName || ' ' || lastName AS "employee"
FROM employees;
END;
我想在此视图中插入值。我创建了INSTEAD OF触发器:
CREATE OR REPLACE TRIGGER trigger_v_emp_list
INSTEAD OF INSERT ON employee_list
FOR EACH ROW
BEGIN
dbms_output.put_line(:new.employee);
END;
但是当我试图编译这个触发器时,我得到错误:
Error(3,24): PLS-00049: bad bind variable 'NEW.EMPLOYEE'
是否有可能在触发器中插入此值以将此值插入employees表中?当然,我会将这个值分成两个独立的值。
答案 0 :(得分:1)
"employee"
使其区分大小写。
当你写道:new.employee时,它试图寻找大写。别名也会发生同样的事情。应该让它发挥作用:
CREATE OR REPLACE VIEW employee_list AS
SELECT firstName || ' ' || lastName AS employee
FROM employees;
END;
