HOW TO CONNECT TO EXTERNAL DATABASE FROM AX

HOW TO UPDATE RECORDS IN SQL FROM AX

1) fIRST CREATE AN ODBC CONNECTION FROM THE SYSTEM TO CONNECT TO THE REQUIRED DATABASES.

    loginProperty.setDatabase("databaseName");

    //Create a connection to external database.

        //then loop through each row in the result.
        while (resultSet.next())
        {
            //It is not possible to get field 3 and then 1.
            //Always get fields in numerical order, such as 1 then 2 the 3 etc.
