Question

我有以下触发器

CREATE OR REPLACE TRIGGER TRG_RESUME_AFTER_UPDATE
BEFORE INSERT OR UPDATE ON RESUME
FOR EACH ROW
BEGIN
    :new.modified_date := SYSTIMESTAMP;
END;

哪个编译

TRIGGER TRG_RESUME_AFTER_UPDATE compiled

但是当我尝试插入时，我收到以下错误：

Error at Command Line : 11 Column : 8
Error report -
SQL Error: ORA-04098: trigger 'D.TRG_RESUME_AFTER_UPDATE' is invalid and failed re-validation
04098. 00000 -  "trigger '%s.%s' is invalid and failed re-validation"
*Cause:    A trigger was attempted to be retrieved for execution and was
           found to be invalid.  This also means that compilation/authorization
           failed for the trigger.
*Action:   Options are to resolve the compilation/authorization errors,
           disable the trigger, or drop the trigger.

PL / SQL对象可以＆＃34;编译＆＃34;但仍然有错误。这听起来像您使用的任何客户端程序可能无法给您正确的反馈。（在SQLPlus中，它应该说＆＃34;使用编译错误创建触发器＆＃34;。）

在任何情况下，要做的事情是查询USER_ERRORS以找出错误是什么。由于触发器非常简单，我猜测表中modified_date不存在，或者它是时间戳无法隐式转换为的数据类型。如果是DATE，则使用SYSDATE比SYSTIMESTAMP更合适。

Oracle触发器编译但插入失败
