How do you write Radio Button values to a Sql Database? - mysql

Question

I've been trying to write to my database and it's nearly complete the only problem Im having is with the radio values as there are two question asked within the webform both with a response of Yes or No. I found an example of this on stackover flow which was
Dim rbval As Integer
If RadioButton1.Checked Then
rbval = 1
Else
rbval = 2
End If
cmd.Parameters.Add(New SqlParameter("#ethics", SqlDbType.Int))
cmd.Parameters("#ethics").Value = rbval
But it didn't work and kept providing me with an error message and highlighting the cmd.ExecuteNonQuery section of the code. I then tried to play with it and put in:
Dim rbval As Integer
If RadYes0.Checked Then
rbval = 1
Else
rbval = 2
End If
cmd.Parameters.Add("#TeaAndCoffee", SqlDbType.Text).Value = RadYes0.Text
And it did work when I selected "Yes" but when I selected "No" the Yes value kept storing in the database and I can see where I went wrong from the code because its always going to select yes from the one I tried to fix. I was wondering if anyone had any suggestions? below is the full code
Dim Con As SqlConnection
Dim cmd As SqlCommand
Dim recordsAffected As String
Dim cmdstring As String = "INSERT [Event Table](EventTypeID, EventName, VenueName, NumberOfGuests, Date, ClientAddress, WeddingName, BuildingAddress, Canapes, Starter, MainCourse, Dessert, TeaAndCoffee) Values(#EventTypeID, #EventName, #VenueName, #NumberOfGuests, #Date, #ClientAddress, #WeddingName, #BuildingAddress, #Canapes, #Starter, #MainCourse, #Dessert, #TeaAndCoffee)"
Con = New SqlConnection("Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\YellowDoor.mdf;Integrated Security=True;User Instance=True")
cmd = New SqlCommand(cmdstring, Con)
cmd.Parameters.Add("#EventTypeID", SqlDbType.Text).Value = EventTypeDD.SelectedValue
cmd.Parameters.Add("#EventName", SqlDbType.Text).Value = EventNametxt.Text
cmd.Parameters.Add("#VenueName", SqlDbType.Text).Value = VenueLoDD.SelectedValue
cmd.Parameters.Add("#NumberOfGuests", SqlDbType.Int).Value = CInt(NumOfGtxt.Text)
cmd.Parameters.Add("#Date", SqlDbType.Int).Value = CInt(DateTxt.Text)
cmd.Parameters.Add("#ClientAddress", SqlDbType.Text).Value = txtAddress.Text
cmd.Parameters.Add("#WeddingName", SqlDbType.Text).Value = txtWedding.Text
cmd.Parameters.Add("#BuildingAddress", SqlDbType.Text).Value = txtBAddress.Text
cmd.Parameters.Add("#Canapes", SqlDbType.Text).Value = txtCanapes.Text
cmd.Parameters.Add("#Starter", SqlDbType.Text).Value = txtStarter.Text
cmd.Parameters.Add("#MainCourse", SqlDbType.Text).Value = txtMainCourse.Text
cmd.Parameters.Add("#Dessert", SqlDbType.Text).Value = txtDessert.Text
Dim rbval As Integer
If RadYes0.Checked Then
rbval = 1
Else
rbval = 2
End If
cmd.Parameters.Add("#TeaAndCoffee", SqlDbType.Text).Value = RadYes0.Text
Con.Open()
recordsAffected = cmd.ExecuteNonQuery
Con.Close()
Response.Redirect("MenuForm.aspx")
End Sub

Look at your table column type in your SQL database. If it's a bit (the most logic way) it's as simple as a pie:
cmd.Parameters.Add("#Yourparam", SqlDbType.Bit).Value = IIf (Radyes0.Checked,1,0)
For Char type:
cmd.Parameters.Add("#Yourparam", SqlDbType.Char).Value = IIf (Radyes0.Checked,"Y","N")
For NVarchar type:
cmd.Parameters.Add("#Yourparam", SqlDbType.Nvarchar).Value = IIf (Radyes0.Checked,"Yes","No")
A simple look at your table design will tell you whichever sentence you need. Use always the same datatype of your database.
By the way: The reason because this example
Dim rbval As Integer
If RadYes0.Checked Then
rbval = 1
Else
rbval = 2
End If
cmd.Parameters.Add("#TeaAndCoffee", SqlDbType.Text).Value = RadYes0.Text
Always saved Yes to your database, is because radiobutton.text gives the text label of the radiobutton, I believe you had a radiobutton for yes and a radiobutton for no, right?
