Accessing Oracle spatial objects (SDO_GEOMETRY) through ODBC/OLEDB

Hello.
I tried googling and reading through these forums and Oracle documentation, but I'm still uncertain on this question:
Are Oracle spatial objects (of type SDO_GEOMETRY) accessible through ODBC and/or OLE DB drivers? Can I retrieve them with SELECT clause? Can I write them to database?
I'm limited to these options because I'm developing Delphi application based on ADO and it must work with different DB servers. However I certainly don't want to implement different ways of accessing database for each server.
If geometry objects aren't suported by ODBC/OLEDB, is there any way to convert SDO_GEOMETRY to (and from) BLOB or string or whatever, so I can read and write them like a normal data field?
Thanks in advance.

The SDO_UTIL package has lots of options to help output spatial data to other formats, and you may be able to use some of them to help.
Some that come to mind are:
SDO_UTIL.TO_WKTGEOMETRY
SDO_UTIL.TO_GMLGEOMETRY
SDO_UTIL.TO_KMLGEOMETRY

Oracle Spatial Object types in Designer 6

Hi all,
I'm trying to design a database that uses the new Oracle Spatial Object types (MDSYS.SDO_GEOMETRY) etc. I have been able to capture the object types from Oracle8i but when i try to save the design in the repository it fails. I am assuming that the version of Oracle Designer I am using does not support MDSYS.SDO_GEOMETRY. Is this correct and if so what version of Designer should I be using?
Martin

Hi Saso,
I'm sorry I don't have any help for you but maybe yo can answer a question for me relating to sdo_geometry. I'm trying to capture a database schema which contains tables with sdo_geometry columns & this fails because I don't have that object defined.
So how do I access the Oracle Object Types branch to define MDSYS.SDO_GEOMETRY? Is it in the object navigator or designer?
Thanks,
Jim Greetham

Oracle Spatial Object

I have more than 2 geographical points In USA saved in oracle DB using geometry object...
are there any function in Oracle Spatial Object that gives me the shortest route to go through all theses geographical points

You would need to create a network with all of your point geometries as nodes and lines as links. See...

Once you do that you can use it to solve your problem (traveling salesman).

How to access Oracle forms 11g application through IE 10 Browser

Hi There,
Application Server Forms and Reports 11.2.0.2 is deployed on weblogic server on OS windows 7.
How to access my application through IE 10 where OS Wondows 8?
Regards,
Asik

does it work with firefox or chrome?
You will find out you deeply have to know formsweb.cfg
However, ie 10 in general with oracle is not a good plan. E.g.:
jpi_classid=clsid:8AD9C840-044E-11D1-B3E9-00805F499D93
I hear ie10 is being deployed to windows 7 and and ie11 is in the works.
which is why I say, oracle needs to develop their own program for launching forms. It doesn't have to be
full featured browser, just enough to run forms. Hint hint hint: you can get the source code of firefox, change it
and compile it. (remove their logos and so on.)

Using OFFLINE_INSTANTIATION with a spatial object - SDO_GEOMETRY type

Hello
I am looking for guidance on the usage of DBMS_REPCAT_RGT.INSTANTIATE_OFFLINE for a table object with an SDO_GEOMETRY
column defined.
The table is:
SQL> descr jtx.jtx_jobs_aoi
Name Null? Type
OBJECTID NOT NULL NUMBER(38)
JOB_ID NUMBER(10)
SHAPE MDSYS.SDO_GEOMETRY
SE_ANNO_CAD_DATA BLOB
The mview is defined as:
CREATE MATERIALIZED VIEW jtx.JTX_JOBS_AOI REFRESH FAST WITH PRIMARY KEY FOR UPDATE AS
SELECT * FROM JTX.JTX_JOBS_AOI@ncgsdb_master_s;
And the command we are using is:
SQL> SET SERVEROUTPUT ON
SQL>
SQL> DECLARE
2 dt_num NUMBER;
3 BEGIN
4 dt_num := DBMS_REPCAT_RGT.INSTANTIATE_OFFLINE(
5 refresh_template_name => 'jtx_refg_dt',
6 user_name => 'jtx',
7 site_name => 'NCGSDB_MVSITE1',
8 next_date => SYSDATE,
9 interval => 'SYSDATE + (1/96)');
10 DBMS_OUTPUT.PUT_LINE('Template ID = ' || dt_num);
11 END;
12 /
When we run this on an 11.1.0.6 database we get:
DECLARE
ERROR at line 1:
ORA-30373: object data types are not supported in this context
ORA-06512: at "SYS.DBMS_REPCAT_RGT_CUST", line 1991
ORA-06512: at "SYS.DBMS_REPCAT_RGT", line 1330
ORA-06512: at line 4
Now the strange thing is this appears to work for ONLINE_INSTANTIATION.
1. Is this supported?
2. If so what are we doing wrong?
Thanks

Update oracle table using data through ODBC

Hi,
I want to update tables inside an Oracle 8i database.
The updates depend on data in a mySql database that I want to approach using an ODBC connection.
I cannot figure out what I need to do to select data from an ODBC source from an oracle session.
What do I have to call this external table ...

Oracle Spatial datatype problems - HELP!!

Can anyone help with this problem. I am using Pro*C/C++ to create a DLL which I am then
linking to another C based application. I am attempting to use Pro*C/C++ to read/write
Oracle Spatial Objects. I have no problem writing Pro*C/C++ code or accessing the
functions in the DLL. My problem is returning values from the DLL functions to my
application. So far the only values I seem able to return are character strings.
Below are two versions of the same function. One that returns a char string and a second
that returns nothing. I would like the second function to work and to return an integer
value for "g_type". Any ideas??? By the way "g_type" is the return value in question. I am
using Oracle Pro*C/C++ 8.1.5 and the V8 Oracle Call Interface for the datatype conversion.
Header files for the Object types have been generated by the Object Type Translator.
THIS FUNCTION WORKS AS EXPECTED. THE PARAMETER G_TYPE RETURNS THE ANTICIPATED STRING VALUE

Hi,
From a quick look I can't see anything wrong. You might want to compare this with the example in $ORACLE_HOME/md/demo/examples.
Also, note that in 9i there will probably be an occi (C++ OCI) available, should this be useful to you.

Converting Spatial Objects to strings

Hi,
Many tools (SQL*Plus, DBVisualizer, various Python modules) seem to be able to retrieve spatial objects as strings. Is this conversion being done by each tool, or does the database know how to convert objects (at least Oracle Spatial objects) to strings?
Is there any way to get string as the result of a query of an Oracle Spatial object with Pro*C or the other precompilers?
Thanks for any information,

Andrew
Is your question about decoding the struct returned in an OCI, Pro*C, or SQLJ program to get at the fields of an sdo_geometry type?
There are oci examples (readgeom.c, writegeom.c) on OTN.

Oracle Spatial system requirements

Hi Experts,
I have a 32bit window 2003 server with 8G memory (PAE added to *g from 2G) with 4 CPU.
we use oracle 10GR4 suppour in stream.
Based on application, I need to install Oracle Spatial ( Actually, I can saw Oracle Spatial object in sysaux tablespace).
I could not find how many system resource requirement to support Oracle Spatial future.
ALso How to check Oracle Spatial is installed into system?
Thanks for HELP!!

You can see what kind of options you have with:
select * from dba_registry;
Do you really need Oracle Spatial or just the free subset Oracle Locator?

Oracle Spatial Datatypes and Dataguard 11g

Hi
Does anyone know if the following datatypes are supported in dataguard 11g for logical standby or physical standby?
SDO_Geometry
SDO_georaster
thanks
sunir

A correction. Logical standby (SQL Apply) doesn't currently natively support spatial data types but sdo_geometry can be supported thru EDS by creating a logging table and two triggers and some manual work. Please check it out from My Oracle Support:
Note 559353.1 - Extended Datatype Support (EDS) for SQL Apply. "Extended Datatype Support (EDS) is the ability for SQL Apply to extend support for additional datatypes that are not natively supported yet by SQL Apply. EDS relies on a new capability in Oracle Database 10g Release 2 Patch Set 3 (10.2.0.4) and Oracle Database 11g Release 1 Patch Set 1 (11.1.0.7) that allows triggers to fire on the logical standby database. "

Does Oracle Lite support Oracle Spatial

Does anybody know whether Oracle Lite or Personal Oracle supports the Oracle Spatial plug-in. Also, for extra credit does anybody know what the difference between Personal Oracle and Oracle Lite is?
We will be needing to provide some attribute and spatial data from our Oracle Enterprise database to several laptops for field personnel using an electronic map we developed. We would like to use a portable version of Oracle that supports Oracle Spatial objects.
Any help would be greatly appreciated.
Thanks
Dan

oh, I didn't realize it was so limited. No, that won't do. We're looking for a "mini" version of the real production database including stored code, triggers etc. Should be scaled down enough to allow rapid syncing of data and schema changes from the production (or really QA) database, but full enough to include the objects necessary to allow the developers to test their code changes to the front end applicaiton on their own environment.
