Question

I have this function that should return 1 if the id exists and 0 if not.
When debugging I found that the query sent to sqlserver is correct and returns 1 row, also I see 1 in the ds Table count =1 but the function returns 0.
Is there a better way to do this ? And what is the problem?

Public Function check_id() As Integer
    Try
        connexion = New SqlConnection(chaine_de_connexion)
        da = New SqlDataAdapter("select * from table_x where id=5", connexion)
        ds = New DataSet
        da.Fill(ds, "Info")
        If ds.Tables("Info").Rows.Count > 0 Then
          Return 1
        Else
          Return 0
        End If
    Catch ex As Exception
       Return 0
    End Try
End Function

Answer 1

The check_id() function returns a YES or NO.. so why not use a Boolean data type?

If you change the return type to Boolean you could do:

Return 0 < ds.Tables("Info").Rows.Count
