使用 Windows Powershell 执行 SQL 脚本

Question

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 drop 和 create 功能，因此无需在命令行末尾添加数据库名称。尝试执行命令行时，我收到一条错误消息，提示

"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"

不确定它是否是调用命令，我已经按照此链接How to execute .sql file using powershell? 中的步骤进行操作。是否有任何机会可以解决此错误。 SQLSERVER 实例已配置为 LocalSystem 而不是网络实例

我已经弄清楚出了什么问题。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，它没有问题。问题出在哪里：

   /****** 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.
