Question

我在数据库中有2个时间范围，名为funtime和funtime1（开始时间和结束时间）。

让我们假设这两个时间集。上午8:00 - 上午9:00 上午9:00 - 上午10:00

逻辑上，没有冲突。但是在我的代码中..它认为是冲突.. 这是我的代码：

Dim str As String = "select * from tbl_funeral where date_burial = '" & t8.Text & "' and (('" & funtime.Text & "' between funtime and funtime1 ) or ( '" & funtime1.Text & "' between funtime and funtime1 ))"
    Dim cmd As New MySqlCommand(str, con)
    Dim da As New MySqlDataAdapter(cmd)
    Dim dt As New DataTable
    Dim ds As New DataSet
    da.Fill(ds)
    dt = ds.Tables(0)
    Try
        If (dt.DataSet.Tables(0).Rows.Count > 0) Then
            MsgBox("There is a conflict on " & t8.Text & " at " & funtime.Text & "!", MsgBoxStyle.Exclamation, "Conflict")
        Else
            'AddSchedule()
            add()

            MsgBox("Scheduling was successful, would you like set more schedule?", MsgBoxStyle.Information, "Success")
            rpt1.Show()
            srt1.Text = "  "
            clearall()
            con.Close()
        End If
    Catch ex As Exception
    End Try

有没有办法让它正常工作？我在此期间所做的是将早上9:01而不是上午9:00放置，这样它就不会发生冲突。感谢〜！
