Question

我正在尝试通过自定义活动使用CRM工作流执行SQL作业。在我的代码中，一个在线教程让我像这样构建它（在c＃中）：

[CrmWorkflowActivity("A test activity to run SQL Jobs")]
public sealed class ExecuteSQLJob : System.Activities.CodeActivity
{

    #region Inputs
    [Input("Job Name")]
    [Default("BMS_ExtractTransformLoad")]
    public InArgument<String> JobName { get; set; }

    [Input("Server Connection")]
    [Default("HBSSQL2008/MSSQLSERVER")]                  //<--This String
    public InArgument<String> ServerName { get; set; }

    [Input("User Name")]
    [Default("-----")]
    public InArgument<String> UserName { get; set; }

    [Input("Password")]
    [Default("-----")]
    public InArgument<String> Password { get; set; }
    #endregion

    protected override void Execute(CodeActivityContext context)
    {
        Server server = new Server(ServerName.Get(context));   //<--Is used here
        try
        {
            server.ConnectionContext.LoginSecure = false;
            server.ConnectionContext.Login = UserName.Get(context);
            server.ConnectionContext.Password = Password.Get(context);
            server.ConnectionContext.Connect();
            Job job = server.JobServer.Jobs[JobName.Get(context)];
            job.Start();
        }
        finally
        {
            if (server.ConnectionContext.IsOpen)
            {
                server.ConnectionContext.Disconnect();
            }
        }
    }
}

但是，当我尝试运行此工作流时，会抛出一条错误消息，指出它无法连接到服务器。（具体来说，错误是在server.ConnectionContext.Connect（）方法调用上抛出的。

问题是serverName字符串吗？如果是这样，我怎样才能找到要使用的正确serverName？

感谢您的帮助！

修改这是一些额外的信息...

这是我第一次获得服务器和实例名称的方式： My SQL Query

这是CRM工作流程中的错误：

抱歉，我最初没有包含此内容，感谢您的帮助到目前为止

Answer 1

尽管与问题并不完全相关，但仍有一个有用的site书签，以帮助您正确获取连接字符串。

对于SQL Server 2008，请在同一网站上查看此linky

服务器字符串的部分是：

服务器= myServerName \ theInstanceName

您在上面的声明中使用了正斜杠

[Input("Server Connection")]
[Default("HBSSQL2008/MSSQLSERVER")]                  //<--This String
public InArgument<String> ServerName { get; set; }

将其更改为：

[Input("Server Connection")]
[Default("HBSSQL2008\\MSSQLSERVER")]                  //<--This String
public InArgument<String> ServerName { get; set; }

可能需要双击它以逃避它..

Answer 2

好的，我想我现在已经知道了。

由于我们的服务器上只运行一个SQL实例，因此实际上我不需要使用 ServerName \ InstanceName 格式。 hbssql2008和HBSSQL2008都允许我连接。此外，知识产权也有效。

另外，我遇到的另一个问题是我使用的用户名和密码来自Windows Integrated Security，而不是sql server的安全性。因此，我在服务器上创建了一个具有适当权限和sql安全信息的新帐户，它允许我连接。

谢谢大家的帮助！

我用什么字符串连接到SQL Server？
