hi..i want to make condition to update my table if there's already same data (in the same column) inserted in the table.

im using

 If String.ReferenceEquals(hotel, hotel) = False Then

        insertDatabase()
    Else
        updateDatabase()

    End If

this is the updateDatabase() code

 Dim sql2 As String = "update infoHotel set nameHotel = N" & FormatSqlParam(hotel) & _
                                                       ", knownAs1 = N" & FormatSqlParam(KnownAs(0)) & _
                                                       ", knownAs2 = N" & FormatSqlParam(KnownAs(1)) & _
                                                       ", knownAs3 = N" & FormatSqlParam(KnownAs(2)) & _
                                                       ", knownAs4 = N" & FormatSqlParam(KnownAs(3)) & _
                                                       " where hotel = " & hotel & ")"

the function manage to go into updateDatabase() but has some error saying

"Incorrect syntax near 'Oriental'."

Oriental is the data inserted in the table. is it suitable to use ReferenceEquals?

im using vb.net and sql database..tq
