Ask : Trigger using spatial operation

Hi all...
I have two tables called OBYEK_PAJAK and AREAL_KEBUN, created using following statement :
CREATE TABLE obyek_pajak (
nop VARCHAR2(9) NOT NULL,
npwp_wp VARCHAR2(15) NULL,
kel_op VARCHAR2(100) NULL,
kec_op VARCHAR2(100) NULL,
luas_areal_op NUMBER NULL,
tgl_ijin_op DATE NULL,
mi_style VARCHAR2(254) NULL,
mi_prinx NUMBER(11,0) NOT NULL,
geoloc SDO_GEOMETRY NULL,
kd_kppbb CHAR(2) NULL
CREATE TABLE areal_kebun (
id_areal_kebun NUMBER NOT NULL,
nop VARCHAR2(9) NOT NULL,
luas_areal_kebun NUMBER NULL,
tahun_tanam VARCHAR2(4) NULL,
mi_style VARCHAR2(254) NULL,
mi_prinx NUMBER(11,0) NOT NULL,
geoloc SDO_GEOMETRY NULL,
kd_areal_kebun VARCHAR2(2) NULL,
kd_tanaman VARCHAR2(2) NULL
both of them have spatial column called geoloc. Column NOP in table AREAL_KEBUN references to column NOP in table OBYEK_PAJAK (so AREAL_KEBUN as a child and OBYEK_PAJAK as a parent)...
I'm using Mapinfo to insert spatial column and others column manually using (i) menu in mapinfo and they're done their job.
Now I'm trying to fill column NOP of AREAL_KEBUN table automatically using trigger when I've finish i.e. draw a polygon IN OBYEK_PAJAK boundary...in the other words I would like to fill my NOP column in AREAL_KEBUN using spatial operation to get NOP value from OBYEK_PAJAK table were related spatially with inserted polygon in AREAL_KEBUN.
I'm trying to create my fool trigger and it not work...here is it :
CREATE OR REPLACE TRIGGER fill_nop_kebun before insert on areal_kebun
REFERENCING OLD AS OLD NEW AS NEW
FOR EACH ROW
BEGIN
DECLARE var_nop VARCHAR2(9)
SELECT a.nop into var_nop from obyek_pajak a, areal_kebun where sdo_anyinteract(a.geoloc,:new.geoloc)='TRUE';
INSERT INTO areal_kebun(:new.nop) VALUES (var_nop);
end;
Anybody has solution for this?? Please help me ASAP and thank for help!
sorry about my poor english....
Regard
Adhi

Hi Adhi,
I have changed FILL_NOP_KEBUN trigger little bit, and now it is working. Changed trigger looks like:
CREATE OR REPLACE TRIGGER FILL_NOP_KEBUN
BEFORE INSERT
ON AREAL_KEBUN
REFERENCING NEW AS new
FOR EACH ROW
DECLARE
var_nop varchar2(9);
BEGIN
SELECT a.nop into var_nop from obyek_pajak a where sdo_anyinteract(a.geoloc,:new.geoloc)='TRUE';
:new.nop := var_nop;
END;
I have tested it on my machine - if new geometry interacts with geometry stored in OBYEK_PAJAK, then appropriate nop value from OBYEK_PAJAK table is inserted into AREAL_KEBUN.

Andrejus

I can't not use spatial operator and index .

Dear all,

Please help me!!!

I would suggest two things:
1) Do not use 0 for the SRID in the user_sdo_geom_metadata entry. There is no 0 SRID value. Look at the sdo_srid value in your geometries, and if it is NULL, specify NULL. If there is a value, match it in the user_sdo_geom_metadata entry.

Problem when using About Operator in Contains Query

Hi,
I'm new to Oracle and this forums too. I have a problem when using about operator in contains query.
I create a table with some records and then create a context index on 'name' column.
CREATE TABLE my_items (
id           NUMBER(10)      NOT NULL,
name         VARCHAR2(200)   NOT NULL,
description VARCHAR2(4000) NOT NULL,
price        NUMBER(7,2)     NOT NULL
ALTER TABLE my_items ADD (
CONSTRAINT my_items_pk PRIMARY KEY (id)
CREATE SEQUENCE my_items_seq;
INSERT INTO my_items VALUES(my_items_seq.nextval, 'Car', 'Car description', 1);
INSERT INTO my_items VALUES(my_items_seq.nextval, 'Train', 'Train description', 2);
INSERT INTO my_items VALUES(my_items_seq.nextval, 'Japan', 'Japan description', 3);
INSERT INTO my_items VALUES(my_items_seq.nextval, 'China', 'China description', 4);
COMMIT;
EXEC ctx_ddl.create_preference('english_lexer','basic_lexer');
EXEC ctx_ddl.set_attribute('english_lexer','index_themes','yes');
EXEC ctx_ddl.set_attribute('english_lexer','theme_language','english');
CREATE INDEX my_items_name_idx ON my_items(name) INDEXTYPE IS CTXSYS.CONTEXT PARAMETERS('lexer english_lexer');
EXEC ctx_ddl.sync_index('my_items_name_idx');Then I perform contains query to retrieve record :
SELECT count(*) FROM my_items WHERE contains(name, 'Japan', 1) > 0;
COUNT(*)
      1
SELECT count(*) FROM my_items WHERE contains(name, 'about(Japan)', 1) > 0;
COUNT(*)
      1But the problem is when I using ABOUT operator like in Oracle's English Knowledge Base Category Hierarchy it return 0
SELECT count(*) FROM my_items WHERE contains(name, 'about(Asia)', 1) > 0;
COUNT(*)
      0
SELECT count(*) FROM my_items WHERE contains(name, 'about(transportation)', 1) > 0;
COUNT(*)
      0I can't figure out what 's wrong in my query or in my index.
Any help will be appreciated.

Hello (and welcome),
You'd be best asking this question in the Oracle Text forum, here:
Text
And by the way, it will help others to analyse if you put {noformat}{noformat} (lowercase code in curly brackets) before and after your code snippets.
Good luck!

Problem when using SDO operations

Hello everyone,
I'm trying to execute some spatial SQL queries and I've come up with a problem: If I enter the following query, the spatial operation (in this case SDO_INSIDE) is executed perfectly and data is returned:
SELECT SUM(fact.quant) as SUM_quant, instalacao.name as Name
FROM fact, instalacao, layer_region, emissao
WHERE fact.instalacao_id = instalacao.instalacao_id AND fact.emissao_id = emissao.emissao_id AND SDO_INSIDE (instalacao.glocal, layer_region.geom)='TRUE'
GROUP BY instalacao.instalacao_id, instalacao.name
ORDER BY instalacao.instalacao_idHowever, if I introduce another GROUP BY element, like this (Where 'emissao' does not have any spatial information, and is not used in the spatial operation) :
SELECT SUM(fact.quant) as SUM_quant, instalacao.name as Name
FROM fact, instalacao, layer_region, emissao
WHERE fact.instalacao_id = instalacao.instalacao_id AND fact.emissao_id = emissao.emissao_id AND SDO_INSIDE (instalacao.glocal, layer_region.geom)='TRUE'
GROUP BY instalacao.instalacao_id, instalacao.name, emissao.poluente
ORDER BY instalacao.instalacao_idthe database apparently gets "stuck" in a loop, and when I cancel it I get the following error:
ORA-13268: error obtaining dimension from USER_SDO_GEOM_METADATA
ORA-06512: at "MDSYS.MD", line 1723
ORA-06512: at "MDSYS.MDERR", line 8
...I can't understand what I'm doing wrong as the "emissao" table is not used in any spatial operation.
Any ideas please?
Thanks in advance,
~Ruben

Although I'm not a 'Spatial guy', maybe you can interprete the action you need to take on the error:
ORA-13268: error obtaining dimension from USER_SDO_GEOM_METADATA
Cause: There is no entry in the USER_SDO_GEOM_METADATA view for the specified geometry table.
Action: Insert an entry for the destination geometry table with the correct dimension information.

How to Use Dimension Operator

Hi
I'm trying to implement SCD Type 2. I have done so using conventional methods.
I have read in some blogs that dimension operator can be used for SCD. Can any one provide me material on how to use Dimension Operator. I tried OWB User guide. But its not useful.
I have seen that we need to create levels. But i dont need levels.
Can somebody please tell me how to use it.
Regards
Vibhuti

Hi Vibhuti,
using dimensions with OWB 10g R2 isn't that difficult. You just create a number of attributes like an ID, a business key and probably a description and then associate each of the attributes with a level. You need at least one level that all the attributes are associated to. Then you can use the slowly changing dimension wizard (SCD) to track changes. In the SCD settings you can determin for which attribute you want to trigger history and which attributes contain your effective date and your end date (if you want to use SCD type II). Obviously you would need two additional attributes in every level for that purpose.

Jörg

How tio use like operator in textitem to get the name

A is the head of Dept 10 and three person are under A namelyHow will you know that B, C and D are under A is there any parent child relationship between Leader and Employee code? If yes, Then you can create the relationship between blocks no need to set where_clause programatically. So, relationship can be like...
leader_block.emp_code = emp_block.leader_code
AND leader_blokc.dep_code = emp_block.dep_codeSo, when you will query data in LEADER block it will show employees which are under LEADER which you queried in LEADER block.
Or if there is no relationship then how will you know that which employee under which leader?
b 002 10 1
c 003 10 1
d 004 10 1
When i enter the name of head corresponding other members in the department will need to display in the
Tabular format Or if you want to query the records only for department relation. Then as you said you create two blocks then create create the relationship using dep_code between those blocks.
like...
leader.dep_code = emp_block.dep_code-Ammad

Rework using reference operation set

Dear Gurus,
Am working in an ECC 6.0 environment.
Want to create rework order using reference operation set.
Master data created:
BoM
Reference Operation set to which the header material is assigned to which a BoM is assigned.
The settings in OPL8 for order type ZXXX are:
Production version : manual selection
Routing:
Application: Routing
Selection Id: RW (priority 01, task list type 'S', and usage 1)
Task list type: S
Routing Selection: 4
BoM:
Application: PP01
Create a production order (CO01), with order type ZXXX. The system asks to select the task list group once the order quantity and dates are entered. On selection of the Group for the reference operation set system generates an error 'No valid BoM exsists for Material xxxxx Plant xxxx'.
SAP helps says - A reference operation set cannot be used directly in production.
Am I doing something wrong?
Your expert advice please.
Tarang

Dear first create a reference operation set go to CA11 just press enter without entering anything then enter plant,usage,status and lot size in component allocation you can select the required BOM and assign with the operation.
and create the order in CO07 enter the plant and order type in next screen don't give any material code give description rework and give the quantity to be reworked and in components give the required components for consumption during rework before this you need to give the reference operation set group and task list in the popup and in settlement rule maintain the category and settlement receiver and save the order.
You can confirm the order in CO15 by providing the order number and enter the yield quantity to confirm and save.
Please note that during this rework order confirmation, only Goods issue will happen based on the input given in the components tab rework order and NO GOODS RECIEPT will happen.
Cheers

Prod.Order Creation- Using Reference Operation set.

Hi
While creating a production order of particular order type,after entering the quantity and order finish date as today's date(05.06.2007),backward scehduling,it's showing no routing found for the material (as we are using REM-Repetitive manufacturing,we are having rate routing) ,and in the same mesaage box itself I choosed the Reference operation set(that I have created today) and entered the group no,and after entering its showing me an error as <b>Ref. operation set 50000008 is not valid according to the selection conditions</b>,
So I created a routing for the same material nd in MRP4 view of the same material under for selection method i kept blank(Selection by order qunatity) and tried to create Prod.order,and there was no problem,but if the same i'm trying to create using Reference operation set I'm not able to create the Production order.
Kindly give me a solution for this,Is there anything to do with order type dependent parameters of the particular order type?
Thanks & Regards
Raj

Hi,
Is your problem solved ?
One more solution to create a order with reference operation set,is to use a trigger point.
Once you create a reference operation set.
Use T.code co31 to create a trigger point, chosoe create order with reference & choose a system status eg: PCNF. & click the user parameter tab.
The system will aks for the reference operation set no & group counter.
Then assign this reference operation set to the routing operation.
When you do partial confirmation of this operation, this will trigger the generation of a order.

Spatial operator issue

Hallo,
I have a general question. I am using a spatial operator. There it is a general rule that the first parameter must come from a indexed table and the second need not to be indexed. As far as good. The other rule is that the first parameter should be the feature that is searched for and the second contains the query window.
If I break the first rule and want to use a non-indexed table geometry an error message ossures. My question concerns the second rule:
If I change the parameters and I set the table with the query window (and it is indexed) first what could happen the worst case?
I have such a case but I can not put the geometry table with the query window to the second parameter because the features I want to search come from the get_geometry function from the topology model and are not indexed.
Thanks in advance Tig

Hallo Bryan,
I am analyzing oracle spatial and the data model I have chosenfor this task is built of object tables. It is not a business solution so it does not really matter. But I have realized several times that it maybe would have been better to work with relational tables. Sometimes it is a lot more work to do to solve a problem.
I am not that happy with the following procedure:
CREATE OR REPLACE PROCEDURE berechneAdressdaten AS
CURSOR cs IS (SELECT a.HAUS_NR,a.HAUS_NR_ZUSATZ,a.STRASSE,
a.GEMEINDE_NAME,a.STRASSENNAME,a.HAK FROM
(SELECT /*+ ordered index(hausanschlusskasten_topo_tab hk stromnetz_8_idx) index(gebaeude_tab g gebaeude_flaeche_sidx) */
G.HAUS_NR, G.HAUS_NR_ZUSATZ, G.STRASSENSCHLUESSEL.STRASSE AS STRASSE,
G.STRASSENSCHLUESSEL.GEMEINDE_NAME AS GEMEINDE_NAME, G.STRASSENSCHLUESSEL.STRASSENNAME AS STRASSENNAME,
HK.HAK, SDO_NN_DISTANCE(1) DISTANCE FROM HAUSANSCHLUSSKASTEN_TOPO_TAB HK,GEBAEUDE_TAB G
WHERE SDO_NN(G.FLAECHE, HK.POSITION.GET_GEOMETRY(),'SDO_NUM_RES=1 UNIT=METER',1)='TRUE')a WHERE a.DISTANCE <=5);
BEGIN
FOR NO IN cs LOOP
UPDATE HAUSANSCHLUSSKASTEN_TAB SET GEMEINDE_NAME=NO.GEMEINDE_NAME,STRASSENNAME=NO.STRASSENNAME,STRASSE=NO.STRASSE,
HAUS_NR=NO.HAUS_NR WHERE NO.HAK=HAK_ID;
END LOOP;
END;
As I mentioned before the parameters I have given to the sdo_nn-operator I have to turn around. SDO_NN(G.FLAECHE, HK.POSITION.GET_GEOMETRY() --> g.flaeche comes from a relational indexed table and hk.position comes from a object relational table with datatype sdo_topo_geometry. For the reason that I need this procedure I build it that way but it is false in the way that g.flaeche is the query window and hk.positon is the parameter I want to select from. But I do not see another way to solve this problem and function-based indexes do not work.
Maybe somebody has an idea.
I would really appreciate!
Thanks Tig

Where can i see whether employee is active or inactive? while i am running retirement action i have used lis9 operation for 0001,007,0008.but its not delimited.can anyone help me?

my client asked me " how to see emploee is active or inactive" for head count plz help me.

Hi,
Try to use 'COP' operation for the Infotypes. We can check in PA30 main screen the status of the employee provided if we have configured the status to be visible in the screen. We can also check in table PA0000 the status of the employee - STAT2 field will provide the status information.
Thanks,

Same Query runs fine in the original database but fails with dblinks. Is it possible to run spatial operations through dblink?
Thanks & Regards,

I've never used spatial myself but this other user had issues with it and dblinks. They ended up using the dblink to create a local materialized view with local indexes and used those.
MapBuilder does not work with DB-link in a spatial view
Found this as well. Does it mean anything to you?
4.2 Querying Spatial Data
This section describes how the structures of a Spatial layer are used to resolve spatial queries and spatial joins.
Spatial uses a two-tier query model with primary and secondary filter operations to resolve spatial queries and spatial joins, as explained in Section 1.6. The term two-tier indicates that two distinct operations are performed to resolve queries. If both operations are performed, the exact result set is returned.
You cannot append a database link (dblink) name to the name of a spatial table in a query if a spatial index is defined on that table.
If a spatial index is created in a database that was created using the UTF8 character set, spatial queries that use the spatial index will fail if the system parameter NLS_LENGTH_SEMANTICS is set to CHAR. For spatial queries to succeed in this case, the NLS_LENGTH_SEMANTICS parameter must be set to BYTE (its default value).

Hi All,
Thank u all for ur replies, but I dint the exact solution for what I'm searching for.
If I use the condition as
"WHERE "Workforce Budget"."Used Budget Amount" BETWEEN MAX("Workforce Budget"."Total Eligible Salaries") AND MAX("Workforce Budget"."Published Worksheet Budget Amount"",
all the data will be grouped with the two columns which I'm considering in the condition.
my actual requirement with this query is to get the required date from a table to generate the report either as daily or weekly or monthly report. If I use repository variables, variables are not getting refreshed until I regenerate the server(which I should not do in my project). Hence I have created a table to hold weekly start and end dates and monthly start and end dates to pass the value to the actual report using between operator.
please could anyone help me on this, my release date is fast approaching.

Start and Stop Trigger using PXI-6120 and DigitalStartAndStopTrigger.vi not working :-(

Hello,
I've been trying for a while now to get my PXI unit to capture a waveform between a Start and Stop (Reference) Trigger using the NI example DigitalStartAndStopTrigger.vi downloaded from the NI website. However, whilst the start trigger and stop trigger seem to be working i.e. the VI runs and stops at the correct times there is never any data read from my DAQmx compatible PXI-6120 card. So I can see the VI is running around the aquisition loop but the Property Node AvailSampPerChan is always returning zero... this has me slightly puzzled. I thought this might just be a driver issue so I've updated my box to the following software versions (see below) and installed the latest drivers e.g. DCDNov07.exe (also from the NI site) but nothing has changed.
my software as of now.
Labview 7.1 (with the 7.1.1 upgrade applied)
Max 4.3.0.49152
DAQmx 8.6.0f12
Trad DAQ 7.4.4f7
before I updated I had the same problem but with the following versions:
Labview 7.1 (with the 7.1.1 upgrade applied)
Max 4.2.1.3001
DAQmx 8.5.0f5
Trad DAQ 6.9.3f4
So to cut a long story short I still have the same problem with the triggers... does anybody have any ideas what is going wrong?
To add insult to injury it the traditional DAQ example ai_start-stop_d-trig.vi was almost working correctly before I did the upgrade. It had the strange behaviour of capturing the AI0 channel but on the wrong edges (e.g. if I set Start on Rise and Stop on Fall it would do the opposite, Start on Fall and Stop on Rise).
I'm going to leave my box doing a mass compile over night but i'd really like it if someone could suggest a solution or point me in the right direction.
Many thanks,
Mike

Hi Graham
I'm out of the lab today but I'll try and answer your questions as best I can...
1) What are the values you have set for Buffer size, Rate, samples per read and post trigger Samples?
At the moment I have all the values (e.g. sample rate, buffer size etc) unchanged apart from the ones I mentioned in my previous post (see above). I have in the past played around with changing the buffer sizes and rates in the example VI but as this appeared to have no effect on the behaviour I now have them setup as in the download.
2) Does the program end after the stop trigger is implemented?
Yep, if I toggle the trigger line high then low I see the program exits the read loop and the VI stops running as expected.
3) Lastly can you give me the details of triggering method. Are you
using a digital train of users set digital pulses? how long is the
program running.I'm using the WriteDigChan.vi to manually toggle the first digital line of the PXI-6733 card which is wired directly to PFI0 of the PXI-6120 card. Generally, I just start the VI running and then toggle the line high, wait a couple of seconds and then toggle it low.
To me it all looks like it should be acquiring samples but as I said yesterday it just refuses to fill the buffer with any data (and hence no samples are read).
Any ideas? and thanks for you help,
Mike

Why do we use Allowed Operations in DML Process

Hello,
Why do we use Allowed Operations in DML Process ??
Can you please clear this confusion:
I am using apex 4.1. oracle 11g R2 SOE ...
Using the Wizard, I created a Form and IR on Dept Table...
In the form page:
- Create Button
The name is "CREATE"
NO Database Action
- DML Process
Allowed Operations: nothing is checked
This will insert a new row in the Dept table
In the form page:
- Create Button
The name is "CREATE2"
Database Action : insert
- DML Process
Allowed Operations: nothing is checked
This will insert a new row in the Dept table
So, What difference does it make if INSERT check box in Allowed Operations of DML Process is TICKED OR NOT ??
