我正在distinct user
从中选择一个IT_Cases_List
并将其存储在一个arraystaff()
. 从这个数组中,我将调用 aStored Procedure
来计算这个用户参与的案例数,(arraystaff(i))
并循环它直到 arraystaff.length-1
但问题是计数不相符。
Sub getStaff(ByVal month As String)
If Not con.State = ConnectionState.Closed Then
con.Open()
End If
Dim s As String = "select distinct Attended_by from IT_Cases_List where month(Resolution_date) ='" & month & "' "
s = s & "And Year(Resolution_date) ='" & ddyear.SelectedValue & "' and Attended_by is not null "
cmd = New SqlCommand(s, con)
da = New SqlDataAdapter
ds = New DataSet
da.SelectCommand = cmd
da.Fill(ds)
If ds.Tables(0).Rows.Count > 0 Then
staffcount = ds.Tables(0).Rows.Count
ReDim arrstaff(staffcount - 1)
For Me.i = 0 To staffcount - 1
arrstaff(i) = ds.Tables(0).Rows(i).Item("Attended_by")
Next
getCases()
End If
End Sub
Sub getCases()
If con.State = ConnectionState.Closed Then
con.Open()
End If
ReDim arrdata(arrstaff.Length - 1, 0)
For Me.i = 0 To arrstaff.Length - 1
cmd = New SqlCommand("get_cases", con)
cmd.CommandType = CommandType.StoredProcedure
cmd.Parameters.Add("@ename", SqlDbType.VarChar).Value = arrstaff(i)
cmd.Parameters.Add("@Yr", SqlDbType.VarChar).Value = ddyear.SelectedValue
cmd.Parameters.Add("month", SqlDbType.VarChar).Value = m
cmd.ExecuteNonQuery()
da = New SqlDataAdapter()
da.SelectCommand = cmd
ds = New DataSet
da.Fill(ds)
If Not IsDBNull(ds.Tables(0).Rows(i).Item("NoCase")) Then
arrdata(i, 0) = ds.Tables(0).Rows(i).Item("NoCase")
End If
Next
cmd = New SqlCommand("delete from cases_Temp", con)
cmd.ExecuteNonQuery()
con.Close()
End Sub
这是我的存储过程
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER procedure [dbo].[get_cases](
@Ename varchar(100),
@Yr varchar(50),
@month varchar(30))
AS
BEGIN
declare @NoCase as int
select @NoCase=COUNT(*)
from IT_Cases_List
where Attended_by= @Ename and month(Resolution_date) =@month and
Year(Resolution_date)=@Yr and Attended_by is not null
insert into cases_temp(Ename,NoCase)
values(@Ename,@NoCase)
select * from cases_Temp
end
我不知道我做错了什么。任何帮助都感激不尽。
更新
好的,我只打过一次电话,getcases
但我仍然遇到同样的问题。
这是我运行程序时得到的:
如果我从数据库中得到 Count(*),我应该得到的病例总数是 132,而我从程序中得到的病例总数是 157 (7+7+20+20+49+49+5)
如果我从 sql 运行查询,这就是我应该得到的
我注意到计数被重复 (7,7,20,20,49,49,5) 而不是 (7,20,49,5,10,27,13)
谁能告诉我我做错了什么?
