I'm new in the group and no have much experience in Spatial area.
I'm looking for information about the posibility of use google places apis to get point of interest from Oracle Spatial / MapBuilder / MapViewer in order to use point of interest from google with own spatial information.
We want to convert our application from Jena TDB to Oracle. In our ontology there are 40.000 triples. Oracle takes 6.8 sec. while Jena TDB takes 0.59 sec. Oracle is much slower than jena TDB. You can see both codes below. There are no inferencing for both apps. How can I improve the performance of Oracle?
Both applications and their data sources are running on same machine.
Oracle code:Oracle oracle = new Oracle(szJdbcURL, szUser, szPasswd); Attachment attachment1 = Attachment.createInstance( new String[] { szSchemaName, szImpactName }, new String[] { }, InferenceMaintenanceMode.NO_UPDATE, QueryOptions.DEFAULT); graph1 = new Graph Oracle Sem(oracle, szModelName, attachment1);m = new ModelOracleSem(graph1); listSubclass = m.listStatements(null,)

I am using Oracle 12c Spatial and Graph and I would like to retrieve the nearest neighbors of a point from a dataset encoded according to GeoSPARQL.I have created a spatial index on the datatype geo:wktLiteral and I to the query so the optimizer pick a plan using the index RDF_V$GEO_IDX. The query I pose is the following:
SELECT geo, wkt
FROM TABLE(SEM_MATCH('
PREFIX geo: <http://www.opengis.net/ont/geosparql#>
SELECT ?geo ?wkt
[code]...
I do not get any error but I do not get any results neither. However, there are a lot of points around POINT(22.39 38.25) in my dataset and if I remove the filter I get results.Do I use orageo:nearestNeighbor in a wrong way?
I was trying to execute a SPARQL through Jena API. I am getting the following exception when invoking the
"ResultSetFormatter.out(System.out, results);" method.
I connect to Oracle using the following Jena code
============================================
Oracle oracle = new Oracle(szJdbcURL, szUser, szPasswd);
Model model = ModelOracleSem.createOracleSemModel(
oracle, szModelName);
==============================================
This is the exception I am getting.

can i create the user-defined functions and use them in the FILTER clause in the sem_match function? there are some built-in functions for the FILTER clasue. however, only one function (DATATYPE(literal)) support for date/time in the built-in functions. i want to implement some user-defined funcitons in the FILTER clause which can check time intervals in ontology. there are some functions about valid time in the WorkSpace Manager such as WM_OVERLAPS, WM_CONTAINS,WM_MEETS, etc. so, can i write some functions using the these valid time functions in WM and use them in the FILTER clause?

when I looked at my Node Ids, they were like +635762253807433724+, +6118969225776891730+. The problem is, I am not the one who is assigning Node Ids, They were automatically generated when inserting TRIPLE data to the rdf table.
Did I miss something when I created my network?

View 1 Replies View RelatedI have a table with column amount as decimal(11,2). I want to store the values as shown below
15.30
but it stores as
15.3
Is it possible to store the value in 15.30?
I have a PL/SQL procedure which gathers data from multiple places as well as calculates some data. I want to store all this in a materialized view.So, I created an object type (I've shortened the definitions):
CREATE OR REPLACE TYPE mf_record_type AS OBJECT
(identifier VARCHAR2(6),
name VARCHAR2(100));
Then created the table type of the object:
CREATE OR REPLACE TYPE mf_table_type IS TABLE OF mf_record_type;
Then in the stored procedure defined a variable of the table type:
v_mf_record mf_table_type := mf_table_type();
Then I loop and populate the record type:
v_mf_record.EXTEND(1);
v_mf_record(x) := mf_record_type(v_rec.identifier, v_mf_detail.name);
When all that is done I try and create the materialized view:
EXECUTE IMMEDIATE ('CREATE MATERIALIZED VIEW mf_snapshot_mv AS
SELECT * FROM TABLE (CAST (v_mf_record AS mf_table_type))');
ORA-00904: "V_MF_RECORD": invalid identifier
Am I doing something wrong here? Can't I create the materialized view based on something other than a physical table?
I need to print a value of a report partially at three places.
Example: If Field Value is 12-24-15 then I need to print 12 at One Place then 24 at second Place and 15 at third Place on the same page of a report and omitting -(Hyphen).
I need to generate random numbers from the range 71 million to 90 million. While generatind the same iam getting the value with decimal places.
How to generate with out decimal places ?
SQL> select ABS(dbms_random.value(71000000,90000000)) from dual;
ABS(DBMS_RANDOM.VALUE(71000000,90000000))

I am developing android application connected to Oracle database using PHP, and I use PL/SQL statements with semantic technologies provided in Oracle(specifically, SEM_MATCH, SEM_MODELS, SEM_RULEBASES or something like this).
However, it doesn't work properly...the connection between android and Oracle works well, though. Also, the query statement is implemented well in the sql developer.The whole php code is shown below :
*<?php*
function db_connect()
*{*
*$db = "(DESCRIPTION=(ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 203.249.105.20)(PORT = 1521)))(CONNECT_DATA=(SID=orcl)))";*

We have just upgraded from APEX 4.0.1 to APEX 4.2. The installation and migration of the applications went very well (after installing the patch for the import of the workspaces :-) ). But we have met a problem - we have a Google reCaptcha plugin on 101 page (authentication page). It has runs pretty well on 4.0.1, but after upgrade whole plugin item just has disappeared from 101. Actually it has disappeared from IE9, IE8, Mozilla 16 and Google chrome. The only browser that is displaying reCaptcha is Opera.
why this happened and how we can fix it? The client wants to make some tests this week and we have to fix the situation.
Is there a way I can integrate my customer base (over 100k with address information) to a Google map. High level, I want my user to enter an address and on google map it should show me markers for existing customers closer to that address.
