Daniel,
the easiest way is to save a copy of the first table, append each of the
other three tables using Table > Append Rows to Table so that you end us
with a single table covering all of your 4 existing tbles. Then
1. edit your new table,
2. select all
3. set target on,
4. draw the zone extent as a rectangle or region
5. select the zone object and
6. Choose objects > erase outside
This will get rid of all data outside that zone.
excuse me if my limited understanding of french meant that I completely
missed the mark.
Robert.

Voici, nous avons une zone de travail � l'intersection de 4 feuillets
topographiques au 20000. Nous voudrions s�lectionner les objets de 4 tables
hypso de ces 4 feuillets qui intersectent avec cette zone afin de les
sauvegarder dans une nouvelles tables (ainsi cr�er une seule table hypso
couvrant la zone). Existe-t-il une syntaxe appropri�e SQL pour obtenir un
tel r�sultat. Merci
