Question

我想用临时位置中的.mdf文件在SQL中创建一个数据库说C:\Temp

我使用以下查询

USE [master]
GO
CREATE DATABASE [database_name] ON 
( FILENAME = N'C:\temp\temp.mdf' ),
( FILENAME = N'C:\temp\temp.ldf' )
FOR ATTACH ;
GO

但我希望在附加时将mdf和ldf文件复制到SQL默认路径(C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\Data\)，因为临时位置可能会在将来被删除或更改。

我该怎么做？

Answer 1

在附加之前，您需要将文件复制/移动到所需的目录中。如果您希望从SQL中完全完成，则需要：

启用xp_cmdshell

执行如下脚本：

USE [master]
GO
DECLARE @result int
EXEC @result = xp_cmdshell 'copy c:\temp\temp.mdf
    C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\Data\temp.mdf';
IF (@result = 0)
    EXEC @result = xp_cmdshell 'copy c:\temp\temp.ldf
        C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\Data\temp.ldf';
    IF (@result = 0)
        CREATE DATABASE [database_name] ON 
        (FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\Data\temp.mdf'),
        (FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\Data\temp.ldf')
        FOR ATTACH ;
        GO
    ELSE
        PRINT 'Failure'
ELSE
    PRINT 'Failure'

Answer 2

为避免由于目录路径中的空格而导致错误，请使用双引号。

USE [master]
GO
DECLARE @result int
EXEC @result = xp_cmdshell 'copy "c:\temp\temp.mdf" "C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\Data\temp.mdf"';

IF (@result = 0)
Begin
    EXEC @result = xp_cmdshell 'copy "c:\temp\temp.ldf" "C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\Data\temp.ldf"';
    IF (@result = 0)
    Begin
        CREATE DATABASE [Your_Database_Name] ON 
        (FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\Data\temp.mdf'),
        (FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\Data\temp.ldf')
        FOR ATTACH ;
    End
    ELSE
        PRINT 'Failure'
End
ELSE
    PRINT 'Failure'
