Spatial Tables to Shape Files

Question

Can someone tell me how I can create shape files from spatial tables. I see a lot of examples for the reverse, but not for create shape files from spatial tables. The federal government has requested this, so I'm kind of stuck. Thanks.

Hi Tomek,
I am new to Oracle spatial and ESRI. I have read conversion to and from ESRI shape file. What I need to do is to convert Oracle spatial coordinate to ESRI coordinate and output ESRI coordinate to external third party software.
I have registered ESRI to Oracle as below:
INSERT INTO SDO_COORD_REF_SYSTEM
SRID, COORD_REF_SYS_NAME, COORD_REF_SYS_KIND,
COORD_SYS_ID, DATUM_ID, GEOG_CRS_DATUM_ID,
SOURCE_GEOG_SRID, PROJECTION_CONV_ID, CMPD_HORIZ_SRID,
CMPD_VERT_SRID, INFORMATION_SOURCE,
DATA_SOURCE, IS_LEGACY,
LEGACY_CODE,
LEGACY_WKTEXT,
LEGACY_CS_BOUNDS,
IS_VALID,
SUPPORTS_SDO_GEOMETRY
VALUES
1000000, 'USGS Albers Conical Equal Area NAD83', 'PROJECTED',
4400, NULL, 10076,
2000006 , NULL, NULL,
NULL, 'USGS',
NULL, 'TRUE',
NULL,
'PROJCS["Equal-Area Projection (United States)",
GEOGCS[ "NAD 83", DATUM ["NAD 83",
SPHEROID ["GRS 80",6378137,298.2572221010002]],
PRIMEM ["Greenwich",0], UNIT["Decimal degree",0.0174532925199433]],
PROJECTION ["Albers Conical Equal Area"],
PARAMETER ["Standard_Parallel_1",29.5],
PARAMETER ["Standard_Parallel_2",45.5], PARAMETER ["Latitude_of_Origin",23],
PARAMETER ["Central_Meridian",-96], UNIT ["Meter",1]]',
NULL,
'TRUE',
'TRUE'
I ran the following:
select MDSYS.SDO_CS.TRANSFORM(
MDSYS.SDO_GEOMETRY(2001,
82473,
MDSYS.SDO_POINT_TYPE(2510416,
2413881,NULL
NULL,NULL
1000000
) from dual
The output is:
(-14497847,5126972)
Is the output in valid ESRI coordinate?
How do you do the conversion otherwise?
Please advise,
Thanks,
Regards,
Michael
