Getting a x- and y-ordinate of a point object

Question

Can anybody tell me how I simply can get de x- and y-coord of a pointobject using sql
I need to update the X and Y field in a spatial table based upon the spatial object in the same table.
It must be a simple SQL, but I can't find it.

Answer 1

Hi Mark,
try it like this:
select * from table ( select b.geom.sdo_ordinates from gemetry_table b
where rownum < 2 )
for geometry_table you have to insert your geo-feature, Rownum is a sample of limiting objects to _1_ Object from
your Objects-List.
Substitute rownum with your unique Object_Identification.
The other way is to write a simple function:
create function get_geom_ordinate( geom, position) returns number
as
begin
return ( geom.sdo_ordinates(position));
end
And use it :
select get_geom( geom, 1) as 'X' , get_geom( geom, 2) as 'Y'
from geometry_table
where Objects# = '0815';
Good Luck
