sql server 过程不返回数据

Question

我的 Sql 程序运行良好。但是当我从 Class 调用它时，它不会返回数据。我得到了这个错误。 Column 'Territory_Name' does not belong to table .我调试了代码，发现所有参数都正确传递了，但是程序没有返回任何数据。如果有人有想法，请帮助我。

我的存储过程是：

Answer 1

这看起来很乱；由于您正在执行多个查询，我认为您需要将数据填充到 DataSet 和 take the 0th Table 或使用正确查询的结果填充 Datatable。

您还可以使用Parameters.AddWithValue() 将代码减少一半，并将using 与连接对象一起使用。

//Your method
DataSet data = new DataSet(); //Note Dataset here ****
string connectionString = ConfigurationManager.ConnectionStrings["connect_str"].ConnectionString;

using(SqlConnection cn = new SqlConnection(connectionString))
{
    string proc = "SPFilterCRMRequests";
    SqlCommand cmd = new SqlCommand(proc, cn);
    cmd.CommandType = CommandType.StoredProcedure;

    cmd.Parameters.AddWithValue("@WeekList", WeekList);
    cmd.Parameters.AddWithValue("@MonthList", pMonthList);
    cmd.Parameters.AddWithValue("@YearList", pYearList);
    cmd.Parameters.AddWithValue("@QuaterList", pQuaterList);
    cmd.Parameters.AddWithValue("@PriorityList", pPriorityList);
    cmd.Parameters.AddWithValue("@Division_IdList", pDivision_IdList);
    cmd.Parameters.AddWithValue("@CRM_Service_Type_IdList", pCRM_Service_Type_IdList);
    cmd.Parameters.AddWithValue("@CRM_Notation_IdList", pCRM_Notation_IdList);
    cmd.Parameters.AddWithValue("@CRM_State_IdList", pCRM_State_IdList);
    cmd.Parameters.AddWithValue("@Service_State_IdList", pService_State_IdList);
    cmd.Parameters.AddWithValue("@Estimated_Amount", pEstimated_Amount);


    SqlDataAdapter da = new SqlDataAdapter(cmd);
    cn.Open();
    da.Fill(data);
}

List<CRM_Doctor_Request> ListCRM_Doctor_Request = 
                         new List<CRM_Doctor_Request>();

foreach (DataRow row in data.Tables[0].Rows) //**** Note 0th table here ******
{
 //rest of the code
}
//...

Answer 2

您的问题是您正在尝试填充表（未定义架构）

将DataTable data = new DataTable(); 更改为DataSet data = new DataSet();

和DataTable table = data 到DataTable table = data.Tables[0]；

您的架构将自动生成，一切正常。

**编辑**

尝试从此设置构建您的查询...

定义这个存储过程

CREATE PROCEDURE [dbo].[TestProc1] 
AS
BEGIN
    SET NOCOUNT ON;

    DECLARE @sql NVARCHAR(MAX) = 'SELECT 1 x UNION ALL SELECT 2'

    EXEC sp_executesql @sql
END

创建一个仅包含此代码的测试应用

class Program
{
    public const string ConnectionString = @"???";

    static void Main(string[] args)
    {
        var t = Execute("TestProc1");

        Trace.Assert(t.Rows.Count == 2);
    }

    private static DataTable Execute(string sql)
    {
        using (var connection = new SqlConnection(ConnectionString))
        {
            connection.Open();

            using (var command = new SqlCommand(sql, connection))
            {
                command.CommandType = CommandType.StoredProcedure;
                var da = new SqlDataAdapter(command);

                var ds = new DataSet();
                da.Fill(ds);

                return ds.Tables[0];
            }
        }
    }
}

连接字符串是你的连接字符串。

这将起作用，并且在功能上等同于您正在做的事情。一旦你有了这个工作，试着建立它来匹配你的具体情况
