<p class=MsoNormal>Hi all,<br>
<br>
Thanks, understand.<br>
<br>
Ok, is there another way to update poi's province.ogc_fid with the bounding
province's ogc_fid ???<br>
Namely i want to learn the province of POI's...<br>
<br>
Regards..<o:p></o:p></p>

<p class=MsoNormal style='margin-bottom:12.0pt'>Hello my friend..<br>
<br>
Your query is not wrong but your record true..<br>
<br>
When you call a subselect to complete your UPDATE operation, this subselect can
be only one row in result return.<br>
To correct this, you must be define one filter to decide what the result you
want to UPDATE.<br>
To see the mistake, execute a subselect {{{ select<b> province.ogc_fid
from province,poi where intersects(poi.the_geom, province.the_geom)=True group
by province.ogc_fid</b> }} and check the number of rows in the resultset.<br>
