Question

我知道我的问题似乎有点宽泛，但我会尽量做到具体而简短。所以我目前正在开发一个关于数据归档的c＃程序。基本上，我会有一个按钮，当我点击它时，它应该在我的SQL服务器数据库中生成新表。

我的问题是执行查询的方法。我已经有一个sql脚本文件列表（用SSMS编写），我想在c＃中执行它们（按顺序）。我应该将脚本硬编码到我的c＃程序中来创建表吗？它看起来像这样：

  private void btnCreateTables_Click(object sender, EventArgs e){
    string query = "IF OBJECT_ID('dbo.AuditCardTypeBenefit_TEST','U') IS NULL ";
    query += "BEGIN ";
    query += "CREATE TABLE[dbo].[AuditCardTypeBenefit_TEST]( "; 
    query += "[AuditID] [decimal](18, 0) IDENTITY(1,1) NOT NULL, ";
    query += "[AuditType] [char](5) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL, ";
    query += "[CardTypeBenefitID] [decimal](18, 0) NOT NULL, ";

    query += "[EventCode] [varchar](8) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL, ";
    query += "[CardTypeGroupID] [varchar](5) COLLATE SQL_Latin1_General_CP1_CI_AS NULL, ";
    query += "[AgeFrom] [int] NULL, ";
    query += "[AgeTo] [int] NULL, ";

    query += "[Gender] [char](1) COLLATE SQL_Latin1_General_CP1_CI_AS NULL, ";
    query += "[CreateBy] [nvarchar](128) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL, ";
    query += "[CreateDate] [datetime] NOT NULL, ";
    query += "[Status] [char](2) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL, ";
    query += "[CancelReason] [varchar](250) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL, ";
    query += "[LastChangeBy] [nvarchar](128) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL, ";
    query += "[LastChangeDate] [datetime] NOT NULL, ";
    query += "[RecordVersion] [timestamp] NOT NULL ";
    query += ") ON [PRIMARY] ";
    query += "END "; }

或者我应该通过在c＃中读取文件（调用它们）来执行脚本文件？我想知道是否有可能按特定顺序阅读它们。此外，脚本文件中的某些SQL语句与c＃中的一些SQL语句不兼容，例如GO语句。

我正在考虑使用上面刚刚发布的代码进行硬编码，因为它可以按照我想要的顺序执行表生成。问题是想象一下，如果我想创建说，50个表，那么代码行将会很长。

我的想法是点击按钮，然后它将在sql server中创建所有表。

什么建议最好？

编辑：我尝试执行sql脚本文件，看看它是否可行。这是它：

private void btnCreateTables_Click(object sender, EventArgs e)
        {
 string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;

            try
            {
                using (SqlConnection con = new SqlConnection(constr))
                {
                    FileInfo file = new FileInfo("C:\\Users\\88106221\\Documents\\PromotionEvent_Test.sql");
                    string script = file.OpenText().ReadToEnd();
                    Server server = new Server(new ServerConnection(con));
                    server.ConnectionContext.ExecuteNonQuery(script);
   }

            }
            catch(Exception ex)
            {

                MessageBox.Show(ex.Message);
                textBox1.AppendText(string.Format("{0}", Environment.NewLine));
                textBox1.AppendText(string.Format("{0} MainPage_Load() exception - {1}{2}", _strThisAppName, ex.Message, Environment.NewLine));
                Debug.WriteLine(string.Format("{0} MainPage_Load() exception - {1}", _strThisAppName, ex.Message));

            }

现在它说无法找到PromotionEvent_Test.sql的目录。我检查了目录，这是正确的。原因是什么？

要运行脚本文件，请使用此C＃方法。

public void CreateDataBase(string FileNameWithPath)
{
    List<string> cmds = new List<string>();
    if (File.Exists(_pFileNameWithPath))
    {
        TextReader tr = new StreamReader(FileNameWithPath);
        string line = "";
        string cmd = "";
        while ((line = tr.ReadLine()) != null)
        {
            if (line.Trim().ToUpper() == "GO")
            {
                cmds.Add(cmd);
                cmd = "";
            }
            else
            {
                cmd += line + "\r\n";
            }
        }
        if (cmd.Length > 0)
        {
            cmds.Add(cmd);
            cmd = "";
        }
        tr.Close();
    }
    if (cmds.Count > 0)
    {
        try
        {
            using (SqlCommand command = new SqlCommand())
            {
                command.Connection = new SqlConnection("ConnectionString To Master");
                command.CommandType = CommandType.Text;
                if (command.Connection.State == System.Data.ConnectionState.Closed)
                {
                    command.Connection.Open();
                }
                for (int i = 0; i < cmds.Count; i++)
                {
                    command.CommandText = cmds[i];
                    command.ExecuteNonQuery();
                }
            }
        }
        catch (Exception exp)
        {
            MessageBox(exp.Message);
        }
    }
}

并使用它

CreateDataBase ("C:\1.SQL");
CreateDataBase ("C:\2.SQL");
CreateDataBase ("C:\3.SQL");
CreateDataBase ("C:\4.SQL");
CreateDataBase ("C:\5.SQL");
CreateDataBase ("C:\6.SQL");
CreateDataBase ("C:\7.SQL");
CreateDataBase ("C:\8.SQL");
CreateDataBase ("C:\9.SQL");
