使用Windows执行SQL脚本Powershell

我有一个"SQL"脚本，需要通过Windows Powershell运行才能创建数据库。该脚本已经具有删除和创建功能，因此不需要在命令行末尾添加数据库名称。试图执行的命令行，当我，说使用Windows执行SQL脚本Powershell

"Invoke-Sqlcmd : A network-related or instance-specific error occurred while establishing a connection to SQL Server 
The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 25 - Connection string is not valid) 
At line:1 char:14 
+ invoke-sqlcmd <<<< -inputfile "c:\A.sql" -serverinstance "Louis_dev\MSSQLSERVER" 
    + CategoryInfo   : InvalidOperation: (:) [Invoke-Sqlcmd], SqlException 
    + FullyQualifiedErrorId : SqlExectionError,Microsoft.SqlServer.Management.PowerShell.GetScriptCommand 

Invoke-Sqlcmd : 
At line:1 char:14 
+ invoke-sqlcmd <<<< -inputfile "c:\A.sql" -serverinstance "Louis_dev\MSSQLSERVER" 
    + CategoryInfo   : ParserError: (:) [Invoke-Sqlcmd], ParserException 
    + FullyQualifiedErrorId : ExecutionFailureException,Microsoft.SqlServer.Management.PowerShell.GetScriptCommand"

不知道这是否是调用命令，我已经按照这个链接How to execute .sql file using powershell?步骤的错误。有没有可能有这个错误的解决办法。 SQLSERVER实例已配置为LocalSystem而不是网络实例

您的SQL实例已启用TCP/IP和命名管道协议？ –

我在哪里可以检查这个？ – Louis

据此我的SQLServer实例安装为LocalSystem。我必须将其更改为网络服务吗？ – Louis

我已经知道出了什么问题。当创建数据库时，脚本中有一行出现问题，当我从脚本中删除该行时没有问题。问题来了：

/****** Object: Database [dbname] Script Date: 01/03/2013 06:53:20 ******/ 
    CREATE DATABASE [Mdbname] -- ON PRIMARY 
    **--(NAME = N'dbname', FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\dbname.mdf' , SIZE = 30417920KB , MAXSIZE = UNLIMITED, FILEGROWTH = 1024KB) 
    -- LOG ON 
    --(NAME = N'dbname_log', FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\dbname_1.ldf' , SIZE = 28333632KB , MAXSIZE = 2048GB , FILEGROWTH = 10%) 
--GO**. Normally its not the best idea to comment those sections out, but i had no   other choice. Databases were created and tables, stored procs, functions and views were all put into their rightful places.
