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

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
This is covered in chapter 32 of the Oracle® Spatial Developer's Guide 11g Release 2 (11.2).

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...
Oracle® Spatial Topology and Network Data Models Developer's Guide
11g Release 2 (11.2) Part II
Once you do that you can use it to solve your problem (traveling salesman).

Oracle table object type - Error

Hi,
I have created an oracle object as like
[CREATE OR REPLACE TYPE t_test_obj IS OBJECT (
testid INTEGER,
testdesc VARCHAR2(64)
Then created the type table from above
[ create or replace type t_table as table of t_test_obj;]
i want to create the table containing the above type like below
create table t_tab_test (test1 t_table); but i received the error as like
ERROR at line 1:
ORA-22913: must specify table name for nested table column or attribute
Requirement: As one my function returns this table type object and i want to insert those values in a table hence i want this. Any other pointers are also helpful.
Please help.
Regards,
Kapil

Thanks for reply.
As i described in Requirement, my function return the table type, hence if i try to insert i get error as below. t_table is the return type from function. I need conversion from table type to object type.
SQL> insert into testing values(1,t_table(1,'a'));
insert into testing values(1,t_table(1,'a'))
ERROR at line 1:
ORA-00932: inconsistent datatypes: expected IRP_DBO.T_TEST_OBJ got IRP_DBO.T_TABLE

Oracle 9i Object Type ..using self

I have created and object with
several attributes of standard oracle datatypes. I have one that is of a custom object type. this object provides encapsulated functionality. I instansiate the internal custom object using a constructor function. the constructor includes the creation of a primary key. once the constructor is done, the object is initialized( an internal flag is set, which should only be done once)
To use this custom object in a member method, I have to do something like this..
( i have summarized code for brevity)
MEMBER FUNCTION foo( ) return obj
is
l_self PARENT_OBJ_TYPE:= SELF;
local INTERNAL_OBJ :=SELF.internal_obj;
begin
local.method1() -- insert record( flag is true)
local.method1() --insert another record( but this time the flag that was set upon construction is now set to FALSE..
I get an error.)
end;
I do not do anything tricky. the behavior seems to be that object types do not keep state appropriately.
any ideas of why this could be happening?

there was no real error code just unexpected behavior. it did not crash. I figured it out. it had to do with passing self as a parameter in out so that it keeps state

Trying to pass Oracle array/object type to Java

I have a Java class with two inner classes that are loaded into Oracle:
public class PDFJ
    public static class TextObject
        public String font_name;
        public int font_size;
        public String font_style;
        public String text_string;
    public static class ColumnObject
        public int left_pos;
        public int right_pos;
        public int top_pos;
        public int bottom_pos;
        public int leading;
        public TextObject[] column_texts;
}I have object types in Oracle as such that bind to the Java classes:
CREATE OR REPLACE TYPE "PROGRAMMER"."PDFJ_TEXT" AS OBJECT
EXTERNAL NAME 'PDFJ$TextObject'
LANGUAGE JAVA
USING SQLData(
"FONT_NAME" VARCHAR2(25) EXTERNAL NAME 'font_name',
"FONT_SIZE" NUMBER EXTERNAL NAME 'font_size',
"FONT_STYLE" VARCHAR2(1) EXTERNAL NAME 'font_style',
"TEXT_STRING" VARCHAR2(4000) EXTERNAL NAME 'text_string'
CREATE OR REPLACE TYPE "PROGRAMMER"."PDFJ_TEXT_ARRAY" AS
TABLE OF "PROGRAMMER"."PDFJ_TEXT";
CREATE OR REPLACE TYPE "PROGRAMMER"."PDFJ_COLUMN" AS OBJECT
EXTERNAL NAME 'PDFJ$ColumnObject'
LANGUAGE JAVA
USING SQLData(
"LEFT_POS" NUMBER EXTERNAL NAME 'left_pos',
"RIGHT_POS" NUMBER EXTERNAL NAME 'right_pos',
"TOP_POS" NUMBER EXTERNAL NAME 'top_pos',
"BOTTOM_POS" NUMBER EXTERNAL NAME 'bottom_pos',
"LEADING" NUMBER EXTERNAL NAME 'leading',
"COLUMN_TEXTS" "PROGRAMMER"."PDFJ_TEXT_ARRAY" EXTERNAL NAME 'column_texts'
CREATE OR REPLACE TYPE "PROGRAMMER"."PDFJ_COLUMN_ARRAY" AS
    TABLE OF "PROGRAMMER"."PDFJ_COLUMN";
/I successfully (as far as I know) build a PDFJ_COLUMN_ARRAY object in a PL/SQL procedure. The PDFJ_COLUMN_ARRAY contains PDFJ_COLUMN objects; each of those objects contains a PDFJ_TEXT_ARRAY of PDFJ_TEXT objects (Example: pdf_column_array(i).pdf_text_array(i).text_string := 'something';). In this procedure, I pass this PDFJ_COLUMN_ARRAY as a parameter to a Java function. I assume the Java function parameter is supposed to be a oracle.sql.ARRAY object.
I cannot figure out how to decompose this generic ARRAY object into a ColumnObject[] array. I also tried Googling and searching the forums, but I can't figure out matching search criteria. I was wondering if anyone here knows anything about passing user-defined Oracle type objects to a Java function and retrieving the user-defined Java class equivalents that they are supposedly mapped to--especially a user-defined array type of user-defined object types containing another user-defined array type of user-defined object types.

INVALID Oracle Spatial objects

Hi,
Me also facing same issue after upgrading the database from 11g R1 to 11g R2. can you please tell how to enable the spacial from invalid to valid .

Mapping spatial object type

I need to map a table with a spatial column of type MDSYS.SDO_GEOMETRY using TopLink. This type is defined as:
CREATE TYPE SDO_GEOMETRY AS OBJECT (
SDO_GTYPE NUMBER,
SDO_SRID NUMBER,
SDO_POINT SDO_POINT_TYPE,
SDO_ELEM_INFO MDSYS.SDO_ELEM_INFO_ARRAY,
SDO_ORDINATES MDSYS.SDO_ORDINATE_ARRAY
Has anyone done this before, or can someone tell me how to do this? Do I need to use ConversionManager or Structure Mapping or something else?

Can I conclude from the lack of replies that this is rather complicated?

Designer and SDO_GEOMETRY object type

I want to have tables with columns of object type MDSYS.SDO_GEOMETRY (Oracle Spatial's type) in Designer 9i and then generate these tables.
So I created in Oracle Object Types branch object type called MDSYS.SDO_GEOMETRY without attributes, methods or source table.
Then I created in Designer table with column named GEOMETRY which has Datatype property empty and Oracle Type property of value MDSYS.SDO_GEOMETRY.
But when I generate this table I get these two messages:
CDS-11349 Warning: The Oracle Object Type MDSYS.SDO_GEOMETRY cannot be generated.
CDS-18025 Error: Table 'PRK_PRIMER_GEO_SDO' will not be created as Oracle Object Type 'MDSYS.SDO_GEOMETRY' is not created
Object type MDSYS.SDO_GEOMETRY already exists in database for sure.
What is wrong here?
Regards
Saso Celarc

I think, Designer cannot handle SDO_GEOMETRY type.
Workaround: use a other datatype/size not used in your schema ( such as varchar2(99) ), generate scripts and do a text substitution on them to SDO_GEOMETRY.

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.

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.

SQL>Now, in that loop woudl it make sense to execute a peck() on all of those entries? Nope. Furthermore as far as I can tell it is not possible to find out what sub-type an object is from with PL/SQL, so you couldn't even use Padders's TREAT ploy.
So: if you want to do something generic use a super-type. If you want to do something specific use a sub-type.
