从代码创建存储过程 - C#

Question

我在 SQL Server 数据库中创建存储过程时遇到问题。这就是我会做的：

public void selectMeetings(String PID)
{
    String connection = "Server=localhost;Database=master;Integrated security=true;";
    SqlConnection Connection = new SqlConnection();

    Connection = new SqlConnection(connection);
    Connection.Open();

    string script = "USE ["+PID+ "] GO CREATE PROCEDURE selectMeetings AS SELECT * FROM dbo.MEETING GO";

    SqlCommand command = new SqlCommand(script, Connection);

    try
    {
       command.ExecuteNonQuery();
    }
    catch (System.Exception ex)
    {
        throw ex;
    }
}

问题是这样的：

“GO”附近的语法不正确。
'CREATE/ALTER PROCEDURE' 必须是查询批处理中的第一条语句

我试图删除 GO，但问题是：

'CREATE/ALTER PROCEDURE' 必须是查询中的第一条语句 批处理。

如何解决这个问题？谢谢

从client code 切换数据库，正如其他人所说，不要发送GO，因为它不是 T-SQL 命令：

public void selectMeetings(String PID)
{
    String connection = "Server=localhost;Database=master;Integrated security=true;";
    SqlConnection Connection = new SqlConnection();

    Connection = new SqlConnection(connection);
    Connection.Open();

    Connection.ChangeDatabase(PID);

    string script = "CREATE PROCEDURE selectMeetings AS SELECT * FROM dbo.MEETING";
    SqlCommand command = new SqlCommand(script, Connection);

    //You're not fishing. There's no point in catch and release
    command.ExecuteNonQuery();
}

最佳实践的进一步修复：

public void selectMeetings(String PID)
{
    String connection = "Server=localhost;Database=master;Integrated security=true;";
    using(SqlConnection Connection = new SqlConnection(connection))
    {
      Connection.Open();

      Connection.ChangeDatabase(PID);

      string script = "CREATE PROCEDURE selectMeetings AS SELECT * FROM dbo.MEETING";
      using(SqlCommand command = new SqlCommand(script, Connection))
      {
        command.ExecuteNonQuery();
      }
    }
}
