使用ISNULL功能，同時插入位列

cmd.CommandText = "INSERT INTO application_main(obligations_is) VALUES(ISNULL('" + convetbit() + "',0))" 

cmd.ExecuteNonQuery()

而且fucnction應像這樣

Public Function convertBit(ByVal dropdownlist As String) AS Boolean 
    Dim value As Boolean = Flase 
    If dropdownlist = "Yes" Then 
     value = 1 
    Else 
     value = 0 
    End If 
     Return value 
End Function

做這樣的：

cmd.CommandText = "INSERT INTO application_main(obligations_is) VALUES(@value)" 
cmd.Parameters.AddWithValue("@value", If ((dropdownlist1.text = "Yes"), True, False)) 
cmd.ExecuteNonQuery()
