SQL Update Column By Adding A Number To Current Int

Question

Simple enough, I can\'t figure out how to add (that\'s +) an integer from a textbox to the integer in the SQL Field.

So for example, the SQL Field may have \'10\' in it

Answer 1

You have to use the correct sql:

Dim sql = "UPDATE PersonsA SET U_G_Studio=U_G_Studio + @ugpoints WHERE Members_ID=@recevierID"

Also use the correct type with AddWithValue:

Using cmd = New SqlCommand(sql, con)
    ' use the using-statement to dispose everything that implements IDisposable, so also the connection '
        cmd.Parameters.AddWithValue("@ugpoints", Int32.Parse(tranamount.Text)) 
    ' .... '
End Using
