This is a typical problem resulting from too large bounds defined. Your
table has a bounds clause included in it's projection definition, which
influences the precision of coordinates. It cannot be changed for existing
table, you must create new one.

Title: Overlap analysis - Oracle tables
David,
A CartesianArea value of -1 is returned
when the corrdinate system is lat/ long. It can only be used with non-lat/
long based tables.
You would need to use SphericalArea(Obj, “UnitName”)
to get the numbers.
Would be interested in your
Dear List members
Just a follow-up on my previous query. While I would like to know how to
do this for my own general knowledge I am also wanting to automate the
"search and replace" tool in MapInfo. If I know what the code is I expect
there would be some way of modifying it so I could carry out

sit behind the MapInfo buttons, tools and menu options

Peter,
If I use CartesianArea() in MapInfo I get
-1.
I guess this is MapInfo’s way of
telling me that there is really no such thing as cartesian area on the surface
of a spheroid.
For testing purposes I created two square
polygons in MapI
Hi Ben,
I'm not sure if it returns multiple rowids but
commandinfo(CMD_INFO_ROWID)
works on a single object after it has beeen selected and reurns the
rowid from
the base table rather than the query. It might be worth a try. You
could try updating a temp column using commandinfo(CMD_INFO_ROWID)
