In addition to what Cetin said, you can partly go around this using

calc max(order_id) to max_order_id

but that would give you only the current records that the user issuing that command sees; it won't necessarily see the value saved by the other user. It will also get your record pointer to eof() and if you have record-level buffering, it will force an implicit tableupdate(). But it will see the values the current user has in the buffers.

Basically, you can't see values which are not saved yet, and then you also shouldn't. The users can still change their minds about saving, or other things can happen that could prevent these values from getting into tables. So your reporting one of the noncommitted values as the current maximum would be inaccurate.
