Question

我正在使用SMO

我很难捕获结果（可能是语法错误消息或数据结果集）就像我们进入SQL Server Management Studio一样。我尝试了几个我在互联网上找到的例子，但是无法按照我的意愿使它工作。

我尝试了以下两种语法

//I am trying catch errors here
int[] results = DBServer.ConnectionContext.ExecuteReader("select * from SomeNonExistingTable");


//I am trying to catch result sets as dataset here
//But I cannot implicitly convert to dataset here using C#
DataSet ds = databaseServer.ConnectionContext.ExecuteWithResults("Select * from mytable");

我试图从以下网站获得一些想法：

SMO ConnectionContext.StatementTimeout setting is ignored

C# SMO Select from Database

Using SMO, still no go... ConnectionContext.ExecuteNonQuery(script) can't understand "GO"

Answer 1

您可以加入try和catch。

try {
        DBServer.ConnectionContext.ExecuteReader("select * from SomeNonExistingTable");
}
catch(Exception ex) {
    while(ex.InnerException) {
        err = ex.InnerException;
        Console.WriteLine(err);
    }
}

在控制台应用程序C＃中，这是一个有效的例子：

var server = new Server(@"YourServer");
        server.ConnectionContext.DatabaseName = "YourDatabase";

        try
        {
            var result = server.ConnectionContext.ExecuteReader("SELECT * FROM YourTable");

            while (result.Read())
            {
                Console.WriteLine(result["ValidColumn"]);
            }

        }
        catch (Exception ex)
        {
            // error handling
            Console.WriteLine(ex);
        }

        try
        {
            var result = server.ConnectionContext.ExecuteWithResults("SELECT * FROM YourTable");

            var i = 0;
            while (i < result.Tables[0].Rows.Count)
            {
                var dr = result.Tables[0].Rows[i];
                Console.WriteLine(dr["ValidColumn"]);
                i++;
            }
        }
        catch (Exception ex)
        {
            // error handling
            Console.WriteLine(ex);
        }

        Console.ReadLine();

脚本运行结果使用SMO for SQL Server
