Question

表上的更新触发器如下所示。

CREATE trigger [HumanResources].[tr_update_department]
on [HumanResources].[Department]
for update
as
begin
insert into HumanResources.tbl_Department_audit
select * from deleted;
end
GO

我基本上在审计表中查找名为tbl_Department_audit的更新行信息。

每当我更新Department表中的单个行时，我都测试了触发器，具有更新前和更新行信息的two行插入到tbl_Department_audit中。

我期望在更新数据之前或更新数据之后仅审核一行，而不是两者。

请将触发器脚本更改为

CREATE trigger [HumanResources].[tr_update_department]
on [HumanResources].[Department]
after update
as
begin
insert into HumanResources.tbl_Department_audit
select * from deleted;
end
GO

更新完成后，只应插入一条记录。

在sql中的表上触发后更新
