问题描述

对不起，我知道标题真的很混乱，但我不知道到底要放下什么.

Sorry I know Title is really confusing but I couldn't figure out what exactly to put down.

基本上我创建了一个查询数据库并显示数据的网格视图.它工作得很好，没有抱怨，但是我现在拥有的是，

Try to change your SELECT Query like below... It will you get the Expected Result...

SQL 小提琴: http://www.sqlfiddle.com/#!3/00b5f/15

我将Table命名为Fruits

SELECT CrateTitle,CrateDescription,CrateID,
stuff(
(
    SELECT ','+ [FruitTitle] FROM fruits WHERE CrateID = t.CrateID FOR XML path('')
),1,1,'') Types_of_Fruits_in_Crate
FROM (SELECT DISTINCT CrateTitle,CrateDescription,CrateID FROM fruits )t

或

创建一个程序

*把这个查询放在那个 Proc*

*调用该 Proc*

*将该结果集分配给 GridView*

您可以使用以下代码将存储的过程结果集分配给 GridView:

You can Assign he Stored Proc Result set to GridView by using the Below Code :

        DataTable dt = new DataTable();
        SqlConnection connection = new SqlConnection("Your Connection String");
        try
        {
            connection.Open();
            string spName = "YOURStoredProcudureName";


            SqlCommand sqlCmd = new SqlCommand(spName, connection);
            SqlDataAdapter sqlDa = new SqlDataAdapter(sqlCmd);
            sqlCmd.CommandType = CommandType.StoredProcedure;


            sqlDa.Fill(dt);
            if (dt.Rows.Count > 0)
            {
                //display the DataTable to a Data control like GridView for example
                GridView1.DataSource = dt;
                GridView1.DataBind();
            }
        }
        catch (System.Data.SqlClient.SqlException ex)
        {
            string msg = "Fetch Error:";
            msg += ex.Message;
            throw new Exception(msg);
        }
        finally
        {
            connection.Close();
        }
