我想将数据库A完全复制到数据库B(相同的SQL Server)中 - 最简单的SQL或实用程序命令是什么? (数据库B应在复制前100%删除)
请注意,它可以是非SQL的东西,但无论如何我需要一键运行它。因此,只要我只需单击一下或从命令行运行复制,一些实用程序也可以接受。
SQL Server 2008R2或2012。
最佳,Askar

我根据大卫的想法提出了一个解决方案。它看起来像这样( Prod - 源数据库,演示 - 目标副本)
DECLARE @backup varchar(300) = 'e:\Prod.bak';
DECLARE @logic_db_file varchar(300) = 'koe';
DECLARE @logic_log_file varchar(300) = 'koe_log';
DECLARE @out_db_file varchar(300) = 'c:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA\Demo.mdf';
DECLARE @out_log_file varchar(300) = 'c:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA\Demo_log.ldf';
PRINT N'Backing up Production database.'
BACKUP DATABASE Prod
TO DISK = @backup WITH FORMAT;
PRINT N'Restoring FILELISTONLY, see log file for data.'
-- Restore the files to Demo
RESTORE FILELISTONLY
FROM DISK = @backup
PRINT N'Getting exclusive access to Demo'
Alter database Demo set single_user with rollback immediate
drop database Demo
PRINT N'Restoring backup to Test database'
RESTORE DATABASE Demo
FROM DISK = @backup
WITH REPLACE,
MOVE @logic_db_file TO @out_db_file,
MOVE @logic_log_file TO @out_log_file
GO
-- if you want you can do some SQL fixes to newly made DB
PRINT N'Changing normal users to demo users, if account type is OK'
USE Demo;
UPDATE USER_ACCOUNTS SET ACCOUNT_TYPE=3 WHERE (STATUS=1) AND (ACCOUNT_TYPE=1);
GO
