我有一個使用SQL數據源綁定它的中繼器，我試圖將用戶選擇 - 某些標籤值插入到數據庫中。將重複項目保存到SQL數據庫
我想弄清楚爲什麼代碼只插入一條記錄到數據庫，而它應該插入所有的中繼器值。
非常感謝您的幫助。
背後代碼：
Public Sub InsertFuncation()
' Define data objects
Dim myConn As SqlConnection
Dim cmd As SqlCommand
Dim sqlstring As String
' Read the connection string
myConn = New SqlConnection("xxx")
' Create command
sqlstring = "INSERT INTO tbl_QZ_AgentResults (Username, ExamID, QuestionID, Question_CorrectAnswer, Question_UserSelection, Question_Score, TRN_AddedOn) VALUES (@Agnt_LdnUsername, @ExamID, @QuestionID, @Question_CorrectAnswer, @Question_UserSelection, @Question_Score, @TRN_AddedOn)"
cmd = New SqlCommand(sqlstring, myConn)
For Each rpItem As RepeaterItem In Repeater1.Items
Dim QID As Label = TryCast(rpItem.FindControl("QuestionIDLabel"), Label)
Dim QCorrectAnswer As Label = TryCast(rpItem.FindControl("lbl_CORRECTANS"), Label)
Dim QUserAnswer As Label = TryCast(rpItem.FindControl("lbl_USERANS"), Label)
Dim QScore As Label = TryCast(rpItem.FindControl("lbl_QSCORE"), Label)
'Perform your insert operation.
' Add command parameters
cmd.Parameters.Add("@Username", Data.SqlDbType.NVarChar)
cmd.Parameters("@Username").Value = User.Identity.Name.Remove(0, 11)
cmd.Parameters.Add("@ExamID", Data.SqlDbType.Int)
cmd.Parameters("@ExamID").Value = Request.QueryString("ExamID").ToString
cmd.Parameters.Add("@TRN_AddedOn", Data.SqlDbType.DateTime)
cmd.Parameters("@TRN_AddedOn").Value = DateTime.Now
If QID IsNot Nothing Then
cmd.Parameters.Add("@QuestionID", Data.SqlDbType.Int)
cmd.Parameters("@QuestionID").Value = QID.Text
End If
If QCorrectAnswer IsNot Nothing Then
cmd.Parameters.Add("@Question_CorrectAnswer", Data.SqlDbType.Int)
cmd.Parameters("@Question_CorrectAnswer").Value = QCorrectAnswer.Text
End If
If QUserAnswer IsNot Nothing Then
cmd.Parameters.Add("@Question_UserSelection", Data.SqlDbType.Int)
cmd.Parameters("@Question_UserSelection").Value = QUserAnswer.Text
End If
If QScore IsNot Nothing Then
cmd.Parameters.Add("@Question_Score", Data.SqlDbType.Int)
cmd.Parameters("@Question_Score").Value = QScore.Text
End If
' Enclose database code in Try-Catch-Finally
Try
' Open the connection
myConn.Open()
' Execute the command
cmd.ExecuteNonQuery()
' Display success message
MsgBox("Entered Successfully !", Me.Page, Me)
'ClearInputs(Page.Controls)
Catch ex As Exception
' Display error message
MsgBox("Error !", Me.Page, Me)
Finally
' Close the connection
myConn.Close()
Response.Redirect("GetResult.aspx?ExamID=" & Request.QueryString("ExamID"))
End Try
' End If
Next
End Sub
