我有一个带有以下代码的存储过程,它在 sql server 中运行良好。我需要使用返回的行来处理堆积柱形图。我不知道如何接收这些行,尽管我尝试使用存储过程代码之后给出的代码来接收这些行。如果有人能找出我做错了什么,我将不胜感激。谢谢 :)
存储过程代码:
ALTER PROCEDURE [dbo].[weekly]
@id_beleg int /* CONTAINS THE ID OF THE MACHINE FOR WHICH THE NUMBER OF ORDERS IS REQUIRED*/
AS
BEGIN
DECLARE @montag DATETIME
DECLARE @weekend DATETIME
SET @montag = DATEADD(wk, DATEDIFF(wk,0,GETDATE()), 0)
/* SET @MONTAG VARIABLE TO THE DATE ON MONDAY OF THE CURRENT WEEK*/
SET @weekend = dateadd(day, 6, @montag)
/* SET @WEEKEND VARIABLE TO THE DATE ON SUNDAY OF THE CURRENT WEEK*/
/* CONTAINS ALL RECORDS OF one PROCESS FOR THE CURRENT WEEK*/
CREATE TABLE #WeeklySieben
(
Tag datetime,
Aufträge_anzahl int,
Anlage varchar(30)
);
INSERT INTO #WeeklySieben (Tag, Aufträge_anzahl, Anlage)
SELECT *
FROM
dbo.Sieben
WHERE
Tag BETWEEN @montag AND GETDATE()
ORDER BY Tag
DECLARE @tempdate datetime
/* CONTAINS ONLY THE UNIQUE MACHINE NAMES*/
CREATE TABLE #Anlage_Sieben
(
Anl varchar(30)
)
/* CONTAINS DATE FOR ALL DAYS OF THE CURRENT WEEK*/
CREATE TABLE #alldays
(
days datetime
)
INSERT INTO #Anlage_Sieben (Anl)
SELECT KURZTEXT as Anl
FROM dbo.tblBELEGUNGSEINHEIT
WHERE ID in (SELECT ID_BELEGUNGSEINHEIT FROM dbo.tblPROZESS_BELEGUNGSEINHEIT WHERE ID_PROZESS = 5)
/* SELECT MACHINE ID WHERE PROCESS IS number 5*/
WHILE @montag <= @weekend
BEGIN
INSERT INTO #alldays (days)
SELECT days = @montag
SET @tempdate= @montag
SET @montag = dateadd(day, 1,@tempdate)
END
/* MACHINE NAME * WEEKDAYS DATE*/
CREATE TABLE #weekdays
(
daydate datetime,
Anlage varchar(30)
)
INSERT INTO #weekdays (daydate, Anlage)
SELECT d.days as daydate
, a.Anl as Anlage
FROM #Anlage_Sieben a
CROSS JOIN #alldays d
/* SELECT NUMBER OF ORDERS ON A PARTICULAR MACHINE FOR ALL WEEK DAYS*/
Select case
when Aufträge_anzahl is null then '0'
else Aufträge_anzahl
end
from #WeeklySieben W right join #weekdays wd on W.Anlage = wd.Anlage and W.Tag = wd.daydate
where wd.Anlage in (select KURZTEXT from dbo.tblBELEGUNGSEINHEIT where ID = @id_beleg )
END
C#代码:
try
{
int a;
string sql = "weekly";
SqlDataAdapter dp = new SqlDataAdapter();
SqlCommand c = null;
SqlDataReader r = null;
DataSet ds = new DataSet();
DataTable dt = new DataTable();
//For creating 'raum' number of stacked column bars
for (int i = 0; i < raum; i++)
{
c = new SqlCommand(sql, conn);
c.CommandType = CommandType.StoredProcedure;
c.Parameters.Add("@raumn", SqlDbType.Int).Value= (int)dblOrders[i];
r = c.ExecuteReader();
dp.SelectCommand = c;
dp.Fill(ds, "Aufträge_anzahl");
dt = ds.Tables["Aufträge_anzahl"];
//For adding points to a stacked column bar
for (int j = 0; j < dt.Rows.Count; j++)
{
a = Convert.ToInt32(dt.Rows[j]);
Chart1.Series[seriesArray[j]].Points.AddY(a);
}
Chart1.DataBind();
dtSr.Clear();
}
}
catch (SqlException ex)
{
Console.WriteLine("SQL Error" + ex.Message.ToString());
}
dblorders 是保存不同机器 ID 的双精度数组,raum 是总机器数。该代码不会产生错误,但不会检索图表中的数据。
