Hi Paul,

Simply, retrieving the updation timestamp and primary keys would be a better option. (i.e. only if your lookup tables have lots of fields)

You can compare these timestamps against your local table's, and issue SQL update for updated ones, SQL DELETE for deleted ones and a loop with INSERT for new ones. This looks like more work and even more SQLs but still it will be a little faster as everything is done on the local machine.

If you have just a couple of fields in the lookup, don't even bother to do such a thing. <g>
