如何通过ADO.NET运行.sql脚本文件？

Question

我想通过ADO.NET使用我的ASP.NET网站运行我的.sql脚本文件.它怎么可能不起作用？

当我尝试

'dbScript is a string and contains contents of the .sql file'
Dim cmd As New SqlCommand(dbScript, con)
Try
    con.Open()
    cmd.ExecuteNonQuery()
Catch ex As Exception
Finally
    con.Close()
    cmd.Dispose()
End Try

当GO语句在脚本中执行时,我得到异常.我该如何解决这个问题？

请参阅我的博客文章,了解如何在SQL中处理GO分隔符 - 简单方法.诀窍是使用SMO的ExecuteNonQuery()方法.例如,这里有一些代码将运行目录中的所有脚本,而不管GO分隔符:

    using System;
    using System.IO;
    using System.Data.SqlClient;
    using System.Collections.Generic;

    //Microsoft.SqlServer.Smo.dll
    using Microsoft.SqlServer.Management.Smo;
    //Microsoft.SqlServer.ConnectionInfo.dll
    using Microsoft.SqlServer.Management.Common;

    public class RunAllSqlSriptsInDirectory
    {
        public static void Main()
        {
            string scriptDirectory = "c:\\temp\\sqltest\\";
            string sqlConnectionString = "Integrated Security=SSPI;" + 
                "Persist Security Info=True;Initial Catalog=Northwind;Data Source=(local)";
            DirectoryInfo di = new DirectoryInfo(scriptDirectory);
            FileInfo[] rgFiles = di.GetFiles("*.sql");
            foreach (FileInfo fi in rgFiles)
            {
                FileInfo fileInfo = new FileInfo(fi.FullName);
                string script = fileInfo.OpenText().ReadToEnd();
                SqlConnection connection = new SqlConnection(sqlConnectionString);
                Server server = new Server(new ServerConnection(connection));
                server.ConnectionContext.ExecuteNonQuery(script);
            }
        }
    }

GO不是Transact-SQL语句,是工具批处理分隔符.在批处理中遇到GO时,服务器正确地抱怨语法错误.您需要将文件拆分为批次,然后执行单个批次.使用正则表达式将文件分批批处理并在单行上识别GO不区分大小写.
