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函数，因此无需在命令行末尾添加数据库名称。当我尝试执行命令行时，我收到一条错误消息

"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invoke命令，我已经按照此链接How to execute .sql file using powershell?中的步骤操作了。是否有可能从此错误中找到解决方法。 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。在创建数据库时，脚本中有一行产生问题，当我从脚本中删除该行时没有任何问题。问题出现在：

   /****** 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.
