Question

下面是mt数据库表

CREATE TABLE [dbo].[mtblLog_Book](
[Logbook_Number] [int] IDENTITY(1,1) NOT NULL,
[Sno] [int] NULL,
[Vehicle_Number] [nvarchar](100) NULL,
[Vehicle_Booking_Date] [datetime] NULL,
[Time_From] [datetime] NULL,
[Time_To] [datetime] NULL,
[KM_Start] [int] NULL,
[KM_End] [int] NULL,
[Total] [int] NULL,
[Vehicle_Used_By] [varchar](100) NULL,
[Cost_Code] [nvarchar](50) NULL,
[Budget_Line] [nvarchar](50) NULL,
[Entry_Date] [datetime] NULL
) ON [PRIMARY]

重复Cost_Code。我需要一个查询，以便我可以获得以下格式的数据

CostCode1
......................
All data which belong to CostCode1
......................

CostCode2
......................
All data which belong to CostCode2
......................

CostCode3
......................
All data which belong to CostCode3
......................

Cont .... to CostCode * n *

Answer 1

如果您想要像上面显示的那样显示。请使用此代码

    protected void show()
    {
     Response.Clear();
     string sql = "select Cost_Code from mtblLog_Book";
     ds = obj.openDataset(sql, schoolCode);

     if (ds.Tables[0].Rows.Count == 0)
     {
        Response.Write("[{\"Records\":\"" + "NA" + "\"}]");
     }
     else
     {
        int i;
        string output;
        for (i = 0; i < ds.Tables[0].Rows.Count - 1; i++)
        {
        string sqlOutput ="Select * from mtblLog_Book where CostCode='"+ds.Tables[0].Rows[i][ "CostCode"].ToString()+ "';";
            Dataset dsOutPut= new Dataset;
          output = "[{\" Logbook_Number \":\"" +dsOutPut.Tables[0].Rows[i]["Logbook_Number"].ToString() + "\",\" Sno\": \"" + dsOutPut.Tables[0].Rows[i][" Sno"] + "\",\" Vehicle_Number\": \"" + dsOutPut.Tables[0].Rows[i][" Vehicle_Number"].ToString() + "\",\" Vehicle_Booking_Date\": \"" + dsOutPut.Tables[0].Rows[i][" Vehicle_Booking_Date"].ToString() + "\" }]"

            Response.Write(output);
            if (i < dsOutPut.Tables[0].Rows.Count - 1)
            {
                Response.Write("\n");
            }
        }
      }
    }

Answer 2

如果您使用的是sql server和SSMS，可以将其设置为将结果输出到文本并执行类似

的操作

DECLARE @costCode NVARCHAR(50)

DECLARE cur CURSOR FOR
SELECT DISTINCT Cost_Code
FROM dbo.mtblLog_Book

OPEN cur
FETCH NEXT FROM cur INTO @costCode
WHILE @@FETCH_STATUS=0
BEGIN
    PRINT @costCode
    PRINT '......................................'
    SELECT * FROM dbo.mtblLog_Book
    WHERE Cost_Code = @costCode
    PRINT '......................................'
              PRINT ''  
END

CLOSE cur
DEALLOCATE cur

然后将结果复制并粘贴到您需要的地方
