Spatial query on join view in another schema

Background:
I have a schema with tables containing four spatial columns per table. I have a second schema that contains join views of the tables in the first schema. The join view consists of the attributes and any other tabular data that is joined via foreign key to non-spatial tables and one of the four geometry columns. I have a third schema that owns no database objects of its own, but has select privilege to the second schema's view objects.
We are using Oracle 10.2.0.2 on a windows platform.
This worked in 9i, the problem only presented itself when we migrated to 10g.
Problem:
When I run a spatial query on a join view in the second schema(the schema that owns the object), it runs and returns results in about a second. When I run the exact same query in the third schema it routinely takes 20-30 seconds.
Here is the query that I run in both schemas with varying query times:
SELECT COUNT(*)
FROM two.join_view_a A
WHERE (MDSYS.SDO_FILTER(A.GEOM, SDO_GEOMETRY(2003,8307,NULL,SDO_ELEM_INFO_ARRAY(1,1003,3),SDO_ORDINATE_ARRAY(26.6396,26.5708,43.346,34.4083)),'QUERYTYPE=WINDOW')='TRUE');
Question:
Why does this happen?
What can I do to fix this problem?
Thanks,
John

Have a read of this posting: Oracle spatial view runing slow as different user
There are details there about the 'optimizer_secure_view_merging' parameter and the effect it can have on cross schema views in 10.2

Spatial query on view to another schema

Hi,
I am getting the following error on this query :
select ufi from cadastre where
sdo_filter(geometry,
mdsys.sdo_geometry(2003,8311,NULL,
sdo_elem_info_array(1,1003,3),
sdo_ordinate_array(130.967,-12.510,131.000,-12.486))) = 'TRUE';
ORA-13226: interface not supported without a spatial index
Cadastre is a view of a table stored in another schema.
This query works :
select ufi from sdo_owner.parcel where
sdo_filter(geometry,
mdsys.sdo_geometry(2003,8311,NULL,
sdo_elem_info_array(1,1003,3),
sdo_ordinate_array(130.967,-12.510,131.000,-12.486))) = 'TRUE';
I have an entry in user_sdo_geom_metadata for CADASTRE , do i also need an entry in user_sdo_index_info for the query to work.
Does any one have any ideas ?
James

Dan,
I have worked out why it happens. We have a parcel table that is made up of polygons and points. The points are parcel's that have no legal boundary or survey boundary, just a point where a house might be located.
What i had forgotten was that i had created a function to convert these points into a polygon on the fly. This buffer function is called from the view.
example
create view cadastre
as
select
ufi,
parcel_key,
buffer(geometry) "GEOMETRY"
from sdo_owner.parcel;
I am guessing that because the geometry is no longer geometry from a table but created geometry it does not have a spatial index associated with it.
Here is the buffer function
CREATE OR REPLACE FUNCTION buffer
geometry MDSYS.SDO_GEOMETRY,
layer_name VARCHAR2
RETURN MDSYS.SDO_GEOMETRY
AS
temp_geom MDSYS.SDO_GEOMETRY;
diminfo MDSYS.SDO_DIM_ARRAY;
start_x FLOAT;
start_y FLOAT;
end_x FLOAT;
end_y FLOAT;
BEGIN
SELECT u.diminfo INTO diminfo
FROM user_sdo_geom_metadata u
WHERE u.table_name = UPPER(layer_name);
IF geometry.GET_GTYPE() = 1 THEN
temp_geom := sdo_geom.sdo_buffer(geometry,diminfo,4,'units=m arc_tolerance=0.005');
return temp_geom;
END IF;
IF geometry.GET_GTYPE() = 2 THEN
temp_geom := sdo_geom.sdo_buffer(geometry,diminfo,4,'units=m arc_tolerance=0.005');
RETURN temp_geom;
END IF;
IF geometry.GET_GTYPE() = 6 THEN
temp_geom := sdo_geom.sdo_buffer(geometry,diminfo,4,'units=m arc_tolerance=0.005');
RETURN temp_geom;
END IF;
RETURN geometry;
END;

Query in Stored Procedure accessing another schema

Hi - this is going to sound kind of strange and even i can't come up with an explanation. My JDK 1.1.7 applet uses a type 4 JDBC thin driver (i think v 8.04.06) to access an Oracle 7.3.4 database. We also have a link with full grants and synonymns to another Oracle schema in an Oracle 8 database. Has never been a problem - we can access anything we need to through queries or stored procedures from either of these databases.
So, i have a new stored procedure that needs to be called through JDBC that queries a table in the Oracle 8 database. For some reason, whenever i execute this stored procedure from java it hangs on this query and the instance needs to be restarted. If i execute that same stored procedure from SQL Plus, it runs fine.
I tried a little test. I put a straight query in my java code that goes directly to that table (no stored procedure involved). It runs great through java!
is this weird or what? my dbas have checked out all privelages and it seems that i have access to everything i could possibly need.
If anyone has any suggestions i would love to hear them.
thanks for your help...

You can only access an object in another user's schema if you either:
(a) Specify the 'other' schema name explicitly: SCHEMA.OBJECT
(b) A synonymn has been created to access the object: CREATE SYNONYM OBJECT FOR SCHEMA.OBJECT.
The user requiring the synonym should create it, or the user owning the object can create a PUBLIC synonym, if they have the authority.
To check my hypothesis, try typing 'DESCRIBE procedure_name' from SQL*Plus as both users.

Renaming View from another schema

Hi,
I've 2 schemas namely department , hr
Now department schema is having one table EMP . And a view is created on that table with the name R_EMP
Schema Name : department
Table Name : EMP
View Name : R_EMP
GRANT SELECT ON R_EMP TO HR ;
In HR schema a synonym has been created on view R_EMP with the name R_EMP .
CREATE OR REPLACE SYNONYM hr.R_EMP for department.R_EMP
Schema Name : hr
Synonym Name: R_EMP
Now I want to rename the view name R_EMP to V_EMP from HR schema only
So, I tried the folloiwng syntax in HR schema (All the operations should be done from this schema only )
[code]
RENAME department.R_EMP to department.V_EMP ;
Error:
ORA-01765: specifying table's owner name is not allowed
[/code]
How to change the syntax to make the statement work from HR schema .
Thank You .

Smile,
The questions is pretty much answered now. You might want to have a look at this as well.
How to rename a table in another user's schema
You can alter the session to set your current schema to the name of the schema where you want to rename the view and then do a direct rename.

Spatial Query that uses Result of another Spatial Query

Hi all,
I am using the SDO_DIFFERENCE Operator to return the difference between a query window and an intersection geometry. This is fine and i get an object back that is cast to a STRUCT using the SDO API. I want then to use this (returned)object in another SQL query that uses the SDO_RELATE Operator. The problem is that i dont know what type it needs to be so that the SDO_RELATE operator will accept it as a valid argument. Has anyone done this before or seen anything like it? Any help will be very much appreciated.
Keith.

Thanks for your help,
I have done the following steps, but i still dont understand why it doesnt work.
CREATE TABLE val_results (sdo_rowid ROWID, result varchar2(1000));
CALL SDO_GEOM.VALIDATE_LAYER_WITH_CONTEXT('SHAPES','SHAPE','VAL_RESULTS');
SELECT * FROM val_results;
1 null     Rows Processed <3>
2 AAARDDAAEAAAAA+AAA     13348 [Element <1>] [Ring <1>]
3 AAARDDAAEAAAAA+AAB     13367 [Element <1>] [Ring <1>]
SELECT shape_id,SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT(c.shape, 0.005)
FROM shapes c;
3     TRUE
2     13348 [Element <1>] [Ring <1>]
1     13367 [Element <1>] [Ring <1>]
If my rectangle and polygon is still invalid, can someone tell me why they are invalid. And how can i make them valid?
Thanks.
UPDATE:
I have solved Polygon issue.
In Spatial Developer's Guide it says:
Simple polygon whose vertices are connected by straight line
segments. You must specify a point for each vertex; and the
last point specified must be exactly the same point as the first
(within the tolerance value), to close the polygon. For
example, for a 4-sided polygon, specify 5 points, with point 5
the same as point 1.
I have added a point to polygon which is same as first point. Now, it can find the point in polygon.
INSERT INTO shapes VALUES (4, 'Polygon', SDO_GEOMETRY(2003, NULL, NULL, SDO_ELEM_INFO_ARRAY(1,1003,1), SDO_ORDINATE_ARRAY(306,193,130,441,489,653,88,183,442,354,306,193)));
But, when i run this query again:
SELECT shape_id,SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT(c.shape, 0.005) FROM shapes c;
4     13349 [Element <1>] [Ring <1>][Edge <4>][Edge <1>]
3     TRUE
2     13348 [Element <1>] [Ring <1>]
1     13367 [Element <1>] [Ring <1>]
it doesn't say TRUE like it did for Circle ??

Spatial Query on ADFBC View Object

Hello,
I'm in the process of migrating some Oracle Forms modules to JDeveloper and I've hit a snag with a query that uses MDSYS.SDO_WITHIN_DISTANCE to find all records within X kilometers from a line which is composed of an undefined set of waypoints.
eg.
Table:
HOTELS
Columns:
ID (Integer)
NAME (Varchar2)
ADDRESS (Varchar2)
LOCATION (Sdo_Geomery - latlong point)
Query:
SELECT *
FROM hotels
WHERE
mdsys.sdo_within_distance (
location,
mdsys.sdo_geometry (
2002,
8307,
null,
mdsys.sdo_elem_info_array (1, 2, 1),
mdsys.sdo_ordinate_array ( 9.45, -39.54, 10, -40.23, ...., .... )
'DISTANCE=7.5 UNIT=KM'
) = 'TRUE';
The SDO_ORDINATE_ARRAY needs to be passed an unknown number of values for the latitude and longitudes to define the line.
The current Oracle Forms module uses a pre-query trigger to dynamically build and apply the entire where clause, concatinating all the supplied values for the line co-ordintates.
I'm now trying to work out what the best way would be to implement this style of query with ADF BC VOs and ADF/JSF pages. If someone has done this already, any guidance on how this can be done would be greatly appreciated.
Thanks,
Michael.

You can use the setWhereClause built-in method on your VO to create the where clause dynamically here too.

Sdo_filter fail when query against a spatial view in different schema

We have a table with X,Y coordinates and would like to run spatial query against it. We do not want to change the table structure, so we opt to use a function based index. USER_SDO_GEOM_METADATA is updated and index is built. Then we created a view with spatial column from the table. Everything works fine with the user who owns the table and view.
When we try to run a spatial query against the view from a different user, it failed with error. However, if we substitute the select from my_view* with the actual SQL statement that created the view, it works. So it looks like Oracle refuse to acknowledge the spatial index if accessed via view. Here is some simplified scripts:
--- connect as USER1.
--update meta data
INSERT INTO USER_SDO_GEOM_METADATA ( TABLE_NAME, COLUMN_NAME, DIMINFO, SRID ) VALUES
('LOCATIONS', 'MDSYS.SDO_GEOMETRY(2001,2264,SDO_POINT_TYPE(NVL(X_COORD,0),NVL(Y_COORD,0),NULL),NULL,NULL)',
SDO_DIM_ARRAY( SDO_DIM_ELEMENT('X', 1300000, 1600000, 1), SDO_DIM_ELEMENT('Y', 400000, 700000, 1) ), 2264 );
--created index
CREATE INDEX LOCA_XYGEOM_IDX ON LOCATIONS
( SDO_GEOMETRY(2001,2264,SDO_POINT_TYPE(NVL(X_COORD,0),NVL(Y_COORD,0),NULL),NULL,NULL)
) INDEXTYPE IS MDSYS.SPATIAL_INDEX;
--create view
CREATE VIEW USER1.MY_VIEW AS SELECT ID ,X_COORD,Y_COORD, SDO_GEOMETRY(2001,2264,SDO_POINT_TYPE(NVL(X_COORD,0),NVL(Y_COORD,0),NULL),NULL,NULL) SHAPE
FROM USER1.LOCATIONS WHERE X_COORD>0 AND Y_COORD>0;
-- run spatial query from view, works fine by user1 by failed on user2.
SELECT SHAPE FROM (
SELECT * FROM USER1.MY_VIEW
) a WHERE sdo_filter (shape, sdo_geometry ('POLYGON ((1447000 540000, 1453000 540000, 1453000 545000, 1447000 545000, 1447000 540000))', 2264), 'querytype=window') = 'TRUE';
-- run spatial query from table directly, simply replace the view with actual statements that created the view. works fine by user1 AND user2.
SELECT SHAPE FROM (

FROM USER1.LOCATIONS WHERE X_COORD>0 AND Y_COORD>0
) a WHERE sdo_filter (shape, sdo_geometry ('POLYGON ((1447000 540000, 1453000 540000, 1453000 545000, 1447000 545000, 1447000 540000))', 2264), 'querytype=window') = 'TRUE';
When run against the view by user2, the error is:
ORA-13226: interface not supported without a spatial index
ORA-06512: at "MDSYS.MD", line 1723
ORA-06512: at "MDSYS.MDERR", line 8
ORA-06512: at "MDSYS.SDO_3GL", line 1173
13226. 00000 - "interface not supported without a spatial index"
*Cause: The geometry table does not have a spatial index.
*Action: Verify that the geometry table referenced in the spatial operator
has a spatial index on it.
Note, the SELECT SHAPE FROM (****) A WHERE SDO_FILTER(....) syntax is a third party application, all we have control is the part inside "(select ...)".
So it appears Oracle is treating view differently. Have attempted fake the view name into USER_SDO_GEOM_METADATA, did not work. Also, granted select on the index table to user2, did not work.
if we re-created the view in user2 schema, it worked for user2 but not user1, so it's not something we can do for every user.
Searched the forum, no good match found. A few posts talked about "union all" in view caused the problem but I do not have the union.
We are only use Oracle 10g Locator, not full spatial edition.
Any ideas?
Thanks!
Edited by: liu.284 on Oct 4, 2011 12:08 PM

It seems a bug, where a function-based spatial index is not correctly handled in a view query transformation.
Not sure if the following works for you or not.
add a new column "shape" (mdsys.sdo_geometry) in table locations, use a trigger and x_coord/y_coord
to set values for this new column, and just create a normal spatial index on this new column. (drop the
function-based spatial index). And create a view like:
CREATE VIEW USER1.MY_VIEW2 AS SELECT ID , X_COORD, Y_COORD, SHAPE
FROM USER1.LOCATIONS WHERE X_COORD>0 AND Y_COORD>0;

Ora-13226 when performing spatial query on view

Hi,
in my database I have a view with spatial column. The view is based on UNION ALL select. When I try to run spatial query on the view, the database returns ora-13226 error. When I recreate the view to consist only one select (without UNION ALL) the spatial query return correct result. Could you pls help me how to do a spatial query on spatial view whose definition contains UNION ALL select?
Thanks
Andrew

Hi,
it's quite simple:
create view test_view as
select id, geometry from table_a
union all
select id, geometry from table_b;
When I try for example:
select *
from test_view
where sdo_relate(geometry, (select geometry from table_c where id=1316),'mask=anyinteract') = 'TRUE';
it throws ora-13226 error.
Interesting is that following query where the geometry is directly included runs well:
select *
from test_view
where sdo_relate(geometry, MDSYS.SDO_GEOMETRY (....),'mask=anyinteract') = 'TRUE';
also when I recreate the test_view as
create view test_view as
select id, geometry from table_a;
then also the first query (with inner select) returns no error.
It's a little bit strange isn't it?

     FROM COLA_MARKETS
    WHERE NAME = 'cola_d');added the necessary entries in USER_SDO_GEOM_METADATA and created a spatial index on COLA_MARKETS (SHAPE). However, when i do a spatial query against this view, i get ORA-03113. A spatial query against the base table works fine. Any ideas why this happens? (This is Oracle 10.2.0.3.0)
Thanks in advance, Markus
PS: This is my spatial query

                         'querytype=window'
                        ) = 'TRUE';

Thank you for your reply. I have tried it with 11.1.0.6.0 today and it works. This might be an issue with 10.2.0.3.0.

Running Spatial Query as different user

Has anyone else run into a problem with running a spatial query that works fine in the scheme that created the tables but when I run it after giving permissions to another user it returns no rows.

from spatial.dime d WHERE d.rcd_nbr IN (select rcd_nbr

where ((lo_add_r >= 1500 and hi_add_r <= 1600) or
(lo_add_l >= 1500 and hi_add_l <= 1600) or
(1500 between lo_add_r and hi_add_r and
1600 between lo_add_l and hi_add_l))
and street = 'WARREN' and dir = 'N' and sttype = 'AV')))
,mdsys.user_sdo_geom_metadata m
WHERE m.TABLE_NAME = 'DIME'), 'MASK = ANYINTERACT' ) = 'TRUE'
and cdate between 20060101 and 20061231

I have a separate schema for querying with and it works fine. I granted select on the needed tables and created synonyms (for convenience). Didn't have to do anything special for spatial indexes at all.
I believe there is an issue doing spatial queries across a DB Link, so that should be avoided.

Spatial Query across schemas. one version enabled table another not -Hanged

Hi,
I am executing a PL/sql procedure where a Spatial query run across two schemas. One table(in x schema) is version enabled and second table(in y schema) is Unversioned. Add to that complexity I am running the procedure from third user logon. I think I have enough previleges, as I won't get any error message.
But, Procedure worked fine when there is no table is version enabled. It started giving problem when one table got version enabled.
I have tried by setting " DBMS_WM.Gotoworkspace('LIVE');" before running spatial query. But still no luck, process just hangs on the spatial query.
I tried by using physical name of the Table (table1_LT) which is making it to work. But, as per Workspace manager guide, applications, programs should NOT use, this physical tables(because it is not the correct way on versioned table).
1. How can I hint to my query, to use a table from only live version?
2. Why Query is hanging forever (even tried by leaving it over night....)
Normally it used to take one or two minutes(before versioning..)
I have posted it Workspace manager forum, But No Luck (people seems to be shy away after seeing "Spatial query" )
Any help is highly appriciated

Hi,
I will need to know more details about the specific query you are performing. So, please do the following:
1. list the actual query that you are using
2. generate an explain plan of the query both before and after the table was version enabled. use @?/rdbms/admin/utlxpls or anything that generates the predicate information.
3. also, give any pertinent details about the table(size of the table, number of rows expected to be returned, column types in the table, etc).
Based on that, I will see if I can suggest a possible hint that may be able to improve the performance of your query.

Ben

VIew of Package body in another schema in EA 3.0

I would like the ability in SQL Developer to view the package body of another schema with the CREATE ANY PRIVILGE.
For instance, in TOAD you can grant access to DBA_SOURCE or SELECT_CATALOG_ROLE and then be able to view another schema's package body.
This is long overdue without having to log into that schema or granting CREATE ANY PRIVILEDGE to user.
This one is really needed

"CREATE ANY PRIVILEGE" is irrelevant to the ability of viewing the source owned by other users.
Please provide exact script for creating a user, which is able to see the code, say in HR schema, via the query
select * from all_source
where owner = 'HR'
and yet missing the nodes in the OtherUsers->Packages->PKG_A->PKG_A Body in the navigator.

How do I view package bodies in another schema ?

For purposes of SOX and security/audit control, we log in under our network id's in our production environment. We have sourcecode compiled into Oracle seeded schemas ( APPS ) so that scheduled jobs are able to run with submitted from the Oracle Applications environment. We don't compile code into our personal network account areas.
I know how to GRANT EXECUTE privs so that we can execute a package in another schema, but what I want to do is to be able to view the sourcecode in another schema. Compile into APPS but be able to see the package body from my network id schema account.
I can't seem to find what the correct permission is anywhere. Granted I can look at DBA_SOURCE to get to it, but I want to use a tool like SQL Developer or TOAD to look at the code in a more presentable and easier to debug manner.
Any help ?

I did some more searching on the forum... seems its already a request... TOAD gives access to DBA_Views to resolve the issue... SQL Developer has not integrated that functionality yet, but forum entries seem to indicate that it is on the horizon.
Thanks for responding though.

Privilege to allow a user to create a view in another user's schema

Hello,
I need to allow a user to create a view in another user's schema.
Say, to connect as USER_A and run statement: 'create view USER_B_SCHEMA.myview as select...'
Is there any way to accomplish that without granting USER_A privilege to CREATE ANY VIEW? I want to keep USER_A at the lowest profile possible.
Thanks!

You have the option to create an stored procedure, here a test case (no optimized, no bug free):
SYS@orcl > create user sp_owner identified by sp_owner;
SYS@orcl > grant create any view to sp_owner;
SYS@orcl> create procedure sp_owner.create_view (
2 view_name varchar2, view_sql varchar2 ) is
3 begin
4 execute immediate 'create view '||view_name||' as '||view_sql;
5 end;
6 /
Procedure created.
SYS@orcl > create user test identified by test;
SYS@orcl > grant create session to test;
SYS@orcl > grant execute on sp_owner.create_view to test;
TEST@orcl> execute sp_owner.create_view('scott.emp_vw','select * from scott.emp')
PL/SQL procedure successfully completed.HTH

Spatial join view

Good afternoon,
I am new on oracle spatial and I have to do a simple spatial join view. So from two table name and a operation I have to create a view that makes a join of type "operation" between two table.
For example, in a high level language:
create or replace view VIEW_NAME as select * from table1,table2 where operation(table1.geom,table2.geom).
Where "operation" could be intersect, touch, overlaps,contains, disjoint...and so on...
I can't find a complete example for my problem.
Thanks for all your help, it is very important.
Best regards
Anna Zanetti

ok..thank you very much.
But If I want to make one of the following operation (BBOX,Beyond,Contains,Crosses,Disjoint,
Equals,Intersects,Overlaps,Touches,Within), what kind of mask have I to use?
I understand that this are the possibile mask:
TOUCH, OVERLAPBDYDISJOINT, OVERLAPBDYINTERSECT, EQUAL, INSIDE, COVEREDBY, CONTAINS, COVERS, ANYINTERACT, ON
I think that there is not a perfect matching, in fact I think that ANYINTERACT is different from intersects!!!
I am wrong?
Is there any table of matching between operations???
Thank a lot
Best regards
Anna Zanetti
