如何从Access DataBase中删除DataRow。 [英] How to delete DataRow from access DataBase.

问题描述

使用窗口管理管理员登录。

我希望最多5次注册，第6次注册会从数据库中删除第1个DataRow。

Working on a window to manage admin logins.
I want a maximum of 5 signup in a way that the 6th one deletes the 1st DataRow from the DataBase.

query = "delete * from adminTable";

清除DataBase中的所有行。

Is clearring all the rows from DataBase.
While

query = "delete * from adminTable where [USER NAMES] = 'singal' ";

清楚我指定的行。

但是我想要第一行，无论如何，只是被删除。

请帮助，谢谢。

Is clearring the row I've specified.
But I want the 1st row only, no matter what, to just get deleted.
Help please, thanks.

推荐答案

请尝试以下方法：

Try the following:

DELETE FROM (SELECT TOP 1 * FROM adminTable)

MSAccess语法有点奇怪





另一个如果哟你有一个自动编号ID字段

MSAccess syntax is a little strange


An alternative if you have an AutoNumber ID field

DELETE FROM adminTable where ID = (SELECT MIN(ID) From adminTable)

但这不是多方面的好习惯 - 用户环境

but this is not good practice in multi-user environments
