Question

我在oracle SQL开发人员身上遇到此错误

create table loan_audit (
employee_id number not null,
tool_no number not null,
tool_out_date date not null,
due_date date not null);

这是我创建的触发器

    CREATE OR REPLACE TRIGGER loan_audit_trigger
AFTER INSERT OR UPDATE OR DELETE
ON loan_02
FOR EACH ROW
BEGIN
  IF INSERTING THEN
    INSERT INTO loan_audit VALUES
    (:new.employee_id, :new.tool_no, :new.tool_out_date, :new.due_date, 'INSERTED', SYSDATE);
  ELSIF UPDATING THEN
    INSERT INTO loan_audit VALUES
    (:old.employee_id,  :old.tool_no,  :old.tool_out_date, :old.due_date, 'UPDATED', SYSDATE);
  ELSIF DELETING THEN
    INSERT INTO loan_audit VALUES
    (:old.employee_id,  :old.tool_no, :old.tool_out_date, :old.due_date, 'DELETED', SYSDATE);
  END IF;  
END;

我收到这些错误

Error(2,5): PL/SQL: SQL Statement ignored
Error(2,17): PL/SQL: ORA-00913: too many values
Error(5,5): PL/SQL: SQL Statement ignored
Error(5,17): PL/SQL: ORA-00913: too many values
Error(8,5): PL/SQL: SQL Statement ignored
Error(8,17): PL/SQL: ORA-00913: too many values

我在做错了什么？我一直试图让这个工作，但继续得到这个错误！在此先感谢您的所有帮助。

在任何insert列出明确的列：

  IF INSERTING THEN
    INSERT INTO loan_audit (employee_id, tool_no, tool_out_date, due_date)
        VALUES ( :new.tool_no, :new.tool_out_date, :new.due_date );
  ELSIF UPDATING THEN
    INSERT INTO loan_audit (employee_id, tool_no, tool_out_date, due_date)
       VALUES (  :old.tool_no,  :old.tool_out_date, :old.due_date );
  ELSIF DELETING THEN
    INSERT INTO loan_audit (employee_id, tool_no, tool_out_date, due_date)
        VALUES (  :old.tool_no, :old.tool_out_date, :old.due_date );
  END IF;

哦，看。该表有四列，但您要插入5.您需要决定是否需要四个或五个并正确声明表。

看起来您还没有employee_id。。。也许你打算：

  IF INSERTING THEN
    INSERT INTO loan_audit (tool_no, tool_out_date, due_date)
        VALUES ( :new.tool_no, :new.tool_out_date, :new.due_date, 'INSERTED', SYSDATE);
  ELSIF UPDATING THEN
    INSERT INTO loan_audit (tool_no, tool_out_date, due_date)
       VALUES (  :old.tool_no,  :old.tool_out_date, :old.due_date, 'UPDATED', SYSDATE);
  ELSIF DELETING THEN
    INSERT INTO loan_audit (tool_no, tool_out_date, due_date)
        VALUES (  :old.tool_no, :old.tool_out_date, :old.due_date, 'DELETED', SYSDATE);
  END IF;

第2行的错误：PL / SQL：语句被忽略;错误（2,17）：PL / SQL：ORA-00913：值太多
