从 T-SQL 存储过程检索到 C# DataTable 的数据存在偏差

Question

当我从 T-SQL 存储过程检索数据到 C# DataTable 时，我确实遇到了一个奇怪的问题，我真的不明白。我在 T-SQL 中得到的结果与检索数据后 DataTable 显示的结果不同。不同的数据意味着数据表中的单元格要么缺少行，要么显示不同的数据。

这是我在 C# 中使用的代码

public DataTable  GetData()
{
    string nameOfSp = "sp_SIA_Get_Ratio_Demand_Receipt";

    DataAccess dataAccess = new DataAccess();

    DataTable dt = new DataTable();

    dataAccess.OpenDatabase(DataAccess.ConnectionTo.SQL);

    SqlConnection sqlCon = dataAccess.GetSqlConnection();

    try
    {
        SqlCommand cmd = new SqlCommand(nameOfSp, sqlCon);
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.CommandTimeout = 1000;

        cmd.Parameters.Add("@COMPANY", SqlDbType.VarChar).Value = filter.CompanyNo;
        cmd.Parameters.Add("@YEARWEEK_FROM", SqlDbType.VarChar).Value = filter.YearWeekFrom;
        cmd.Parameters.Add("@YEARWEEK_TO", SqlDbType.VarChar).Value = filter.YearWeekTo;
        cmd.Parameters.Add("@USERNAME", SqlDbType.VarChar).Value = filter.UserName;

        SqlDataAdapter da = new SqlDataAdapter(cmd);
        da.Fill(dt);
    }
    catch (Exception ex)
    {
        MessageBox.Show("Could not retrieve data from stored procedure " + ex.Message);
    }

    dataAccess.CloseDatabase();

    return dt;
}

这是 SQL 语句：

ALTER PROCEDURE [dbo].[sp_SIA_Get_Ratio_Demand_Receipt]
    @COMPANY as varchar(4),
    @USERNAME as varchar(50),
    @YEARWEEK_FROM as varchar(6),

我从SQL语句得到的结果：

我从DataTable得到的结果：

我将 C# 中的代码从异步改回，因为我认为这会导致问题。

您正在调用一个名为 sp_SIA_Get_Ratio_Demand_Receipt 的存储过程，但您只向我们展示了一条 SQL SELECT 语句。我们需要查看存储过程的其余部分。可能是 WHERE 子句导致了差异。

要查看发送到 SQL Server 的内容，您可以使用 SQL Server Profiler 等探查器。
