MS SQL 批量创建用户和数据库

Question

我正在探索设置 SQL 2016 数据库服务器的选项，以支持教授学生数据库基础知识。课程将有近200名学生。

我想通过脚本自动创建所有用户帐户和关联的数据库 - 这意味着需要同时为每个用户创建数据库。基本上每个学生的用户登录名和数据库都会被命名为学生的ID。登录身份验证将是 SQL 身份验证，而不是 Windows，因为实验室 PC 不在 AD 上。

如果有人能指出我可以修改或使用的任何脚本的方向，那将非常有帮助 - 基本上，如果我沿着这条路走下去，我每年都需要这样做，所以脚本将是最佳的。

谢谢 D.

Answer 1

使用创建登录命令。以下示例将创建用户 myDBUser.

USE [master]
GO
CREATE LOGIN [myDBUser] WITH PASSWORD=N'myPassword' MUST_CHANGE, DEFAULT_DATABASE=[myDB], CHECK_EXPIRATION=ON, CHECK_POLICY=ON
GO

当然还要为这样的登录创建数据库用户

USE [myDB]
GO
CREATE USER myDBUser FOR LOGIN myDBUser;

Answer 2

我认为这样的方法可行，您可能需要更改登录周围的动态 SQL 位，因为它有点乱七八糟。

--Create table for bulk insert
Create Table UserNameCSV (UserID int, UserName Varchar(100))

--Insert login names from C:\csvtest.txt
BULK
INSERT UserNameCSV
FROM 'c:\csvtest.txt'
WITH
(FIELDTERMINATOR = ',', ROWTERMINATOR = '\n')
GO

-- Run Cursor
Declare @UserName Varchar(100)

Declare db_Cursor CURSOR FAST_FORWARD FOR
Select UserName from UserNameCSV

OPEN db_Cursor
FETCH NEXT FROM db_Cursor INTO @UserName

WHILE @@FETCH_STATUS = 0
BEGIN

DECLARE @Sql varchar(max) ='CREATE DATABASE ' + @UserName
DECLARE @Sql1 varchar(max) = 'USE [' + @UserName + ']'
DECLARE @Sql2 varchar(max) = 'CREATE LOGIN ' + @UserName + ' WITH PASSWORD=N''myPassword123!'' MUST_CHANGE, CHECK_EXPIRATION=ON, CHECK_POLICY=ON'

EXECUTE(@Sql)
EXECUTE (@Sql1)
EXECUTE (@Sql2)


FETCH NEXT FROM db_Cursor into @UserName

END

CLOSE db_Cursor
DEALLOCATE db_Cursor

使用动态 Sql 和 while 循环我们可以循环学生姓名并创建数据库 logins.Hope 它可以帮助你
