使用python子进程执行SQLCMD

我想从.dat文件还原MS SQL数据库

通过在Windows PowerShell上调用以下命令/语句或将其保存在.bat文件中并运行文件本身，我成功地完成了此操作：

sqlcmd -S POLIVEIRA-PC\MSSQLSERVER2008 -Q "RESTORE DATABASE [Odemira_2012-07-01_021501] FROM DISK=N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER2008\MSSQL\Backup\ODEMIRA2013\Odemira_2012-07-01_021501' WITH FILE=1, MOVE N'Odemira_Data' TO N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER2008\MSSQL\DATA\Odemira_2012-07-01_021501.MDF', MOVE N'Odemira_Log' TO N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER2008\MSSQL\DATA\Odemira_2012-07-01_021501_1.LDF', NOUNLOAD, STATS=10"

但是，由于我需要在不同的数据库中多次重复此指令，因此我希望使用Python在循环中执行此操作。我尝试使用子流程模块复制上述指令。没有成功

我的Python代码如下所示：

import subprocess

host = 'POLIVEIRA-PC\\MSSQLSERVER2008'
mssql_dir = 'C:\\Program Files\\Microsoft SQL Server\\MSSQL10_50.MSSQLSERVER2008\\MSSQL\\DATA\\'
db_dir = 'C:\\Program Files\\Microsoft SQL Server\\MSSQL10_50.MSSQLSERVER2008\\MSSQL\\Backup\\ODEMIRA2013\\'
db = 'Odemira_2012-07-01_021501'

statement = '"RESTORE DATABASE [' + db + '] FROM DISK=N\'' + db_dir + \
            db + '\' WITH FILE=1, MOVE N\'Odemira_Data\' TO N\'' + mssql_dir + \
            db + '.MDF\', MOVE N\'Odemira_Log\' TO N\'' + mssql_dir + \
            db + '_1.LDF\', NOUNLOAD, STATS=10"'

subprocess.call(["sqlcmd", "-S", host, "-Q", statement])

在Windows PowerShell上运行此python脚本时，出现以下错误：

PS C:\Users\POliveira\Dropbox\Academia\IST\Dissertacao_de_Mestrado\SQL> python .\lib\temp.py
Sqlcmd: 'RESTORE DATABASE [Odemira_2012-07-01_021501] FROM DISK=N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER2008\MSSQL\Backup\ODEMIRA2013\Odemira_2012-07-01_021501' WITH FILE=1, MOVE N'Odemira_Data' TO N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER2008\MSSQL\DATA\Odemira_2012-07-01_021501.MDF', MOVE N'Odemira_Log' TO N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER2008\MSSQL\DATA\Odemira_2012-07-01_021501_1.LDF', NOUNLOAD, STATS=10\""': Unexpected argument. Enter '-?' for help.

我不知道我错过了什么。我试着用倒斜杠避开双引号（“RESTORE…10”），但也没用

---

编辑：我确实尝试在subprocess.call上添加标志shell=True，但最后出现了相同的错误。

删除语句周围的双引号，如下所示：

statement = 'RESTORE DATABASE [' + db + '] FROM DISK=N\'' + db_dir + \
            db + '\' WITH FILE=1, MOVE N\'Odemira_Data\' TO N\'' + mssql_dir + \
            db + '.MDF\', MOVE N\'Odemira_Log\' TO N\'' + mssql_dir + \
            db + '_1.LDF\', NOUNLOAD, STATS=10'
