Track a StringLine with a Trigger

Hi,
(sorry for my bad english)
I need to know if i can track a stringline with a trigger. For example, in my case, i've to colums called "From" and "To". From contains a CONTROID() coordinates, anche TO contains CENTROID() coordinates. Now, can i track a line in a colums "LINE" with a trigger? All in automatic?
There is a method to take the coordinates from "FROM" and "TO" and track an automatic stringline with a trigger?
The Table is composed by:
ID | FROM | TO | LINE
Thanks a lot (sorry for my bad english).

Ok, i means a simple line (Line Sting http://www.oracle.com/pls/db111/to_URL?remark=ranked&urlname=http:%2F%2Fdownload.oracle.com%2Fdocs%2Fcd%2FB28359_01%2Fappdev.111%2Fb28400%2Fglossary.htm%23sthref2928)
This is the Trigger:
CREATE OR REPLACE TRIGGER "TRIGGERPERCORSO"
BEFORE INSERT OR UPDATE OF luo_nomeluogo ON "SPOSTAMENTI"
FOR EACH ROW
DECLARE

presenza NUMERIC;
BEGIN
SELECT COUNT(*) INTO presenza
FROM spostamenti
WHERE ope_codiceopera = :new.ope_codiceopera;
IF (presenza >= 1) then
     SELECT luo_nomeluogo INTO vecchioluogo
     FROM (SELECT * FROM spostamenti
     WHERE ope_codiceopera = :new.ope_codiceopera
     ORDER BY codicespostamento DESC)
     WHERE ROWNUM <2;
     SELECT SDO_GEOM.SDO_CENTROID (c.COLLOCAZIONE, m.diminfo) INTO partenza
FROM LUOGHI c, user_sdo_geom_metadata m
WHERE m.table_name = 'LUOGHI' AND m.column_name = 'COLLOCAZIONE' AND c.nomeluogo = vecchioluogo;
SELECT SDO_GEOM.SDO_CENTROID (d.COLLOCAZIONE, n.diminfo) INTO arrivo
FROM LUOGHI d, user_sdo_geom_metadata n
WHERE n.table_name = 'LUOGHI' AND n.column_name = 'COLLOCAZIONE' AND d.nomeluogo = :new.luo_nomeluogo;
INSERT INTO VISUALPERCORSO(LUOGOPARTENZA, OPE_CODICEOPERA, COORDINATEPARTENZA, LUOGOARRIVO, COORDINATEARRIVO) VALUES (vecchioluogo, :new.ope_codiceopera, partenza, :new.luo_nomeluogo, arrivo);
END IF;
END;
So, now i need to track a line (with oracle spatial) from "COORDINATEPARTENZA" to "COORDINATE ARRIVO". With another trigger.
Can you understand now?

Thanks a lot (sorry for my bad english).

"COORDINATEPARTENZA" and "COORDINATEARRIVO" are points, correct?
If I understand, you need to create a line from initial point (PARTENZA) to final point (ARRIVO) in a trigger.
Yes, you can do it.
Anyway, you can write to me in italian (miguel dot fornari at gmail).

How to Create a table with numeric trigger for INSERT

Let me start off by saying that I am very new to DBMS.
I need to create a Table with INSERT Trigger. I am not exactly sure if I need to have a BEFORE ot AFTER insert trigger but leanning towards AFTER.
I have a Java code that will need insert a row each time that piece of code is executed. I would also like an oracle trigger to insert a unique numeric value (REC_ID) for that that record.
I am totally lost and I am not sure how to go about it. Can you point me to the right direction?
Basically my table will have the following 3 columns
REC_ID NUMBER NOT NULL (uniquie value inserted by the trigger)
PROPERTY_NAME VARCHAR2(100 BYTE)
PROPERTY_VAL VARCHAR2(100 BYTE)
Thank you in advance

Ok, the problem is: the table 'estadia' means 'stay' and 'quarto' means 'room'. I need to, before inserting on 'estadia', to check if that room is available or not.
I may do this:
insert into estadia values (4, 3, *3*, to_date('09.12.15', 'yy.mm.dd'), to_date('10.02.25', 'yy.mm.dd'));
but if, after this command, i do this:
insert into estadia values (5, 4, *3*, to_date('09.12.15', 'yy.mm.dd'), to_date('10.02.25', 'yy.mm.dd'));
it accepts and it shouldn't, because I'm putting users 3 and 4 in the same room at the same time.
the 3rd field is the room id and the next two fields are the entry date (data_entrada) and the exit date (data_saida). If a room is related to a specific stay in which the exit date hasn't gone by, that room shouldn't be available. Also, the exit date may be null, meaning that the exit date is unknown.
I hope to have been clear about my question.
Thanks, Chiapa

This is a fairly easy business rule which can be implemented using triggers. Here goes.
Tables (my version):
drop table stay;
drop table room;
create table room
(room_id     number not null primary key
,other_col     varchar2(10) not null)
create table stay
(stay_id     number not null primary key
,room_id     number not null references room(room_id)
,arrive          date not null check(trunc(arrive)=arrive)
,depart          date          check(trunc(depart)=depart)
,unique (room_id,arrive)
,check(arrive <= depart))
/The rule you are trying to implement is this one:
create or replace assertion no_overlap as
check(not exists
        (select 'two overlapping stays for a room'
         from stay s1
             ,stay s2
         where s1.room_id = s2.room_id
           and s1.stay_id != s2.stay_id
           and (s1.arrive between s2.arrive and nvl(s2.depart,s1.arrive) or
                s1.depart between s2.arrive and nvl(s2.depart,s1.depart))
/Sometime in a far far away future, we may be done now. That future has still to arrive though.

Auto populate text fields with a trigger such as entering text into input fields in ADF

Hello all,
I am not able to auto populate text fields with a trigger such as entering text into input fields in ADF.
I tried AdfFacesContext.getCurrentInstance().addPartialTarget(val); in the back end using setter method of input text field.
its not working ..
is there any way to achieve it
Regards,
Shakir

Hi,
Always mention your JDev version.
The valueChangeListener would fire only when you set the autoSubmit property of the field to true. Can you elaborate your requirement? What do you mean by related data? Are you performing some sort of search?
If you want to get the value you entered on the field, just set autoSubmit to true and get the new value from the valueChangeListener. If your requirement is something like as and when you type, do something, you need to check out this approach :https://blogs.oracle.com/groundside/entry/auto_reduce_search_sample

I am trying to import standard midi file that I created in Band in a Box into Logic Pro 9. I can not get all the track to play with internal instrument sounds... only the piano track. how can I get the others to play... drums, bass etc???? Help

I am trying to import standard midi file that I created in Band in a Box into Logic Pro 9. I can not get all the track to play with internal instrument sounds... only the piano track. how can I get the others to play... drums, bass etc???? Help

Don't drag the midi into an open Logic project. The tracks won't set up correctly.
'Open' the midi file with Logic as if it were a Logic project. Then all the tracks will be set up so you can start editing them and applying better saved sounds and instruments, but you'll be at a starting place where you can hear what's going on.

Problem with this trigger

Hello, I am new to Oracle and I am having problems with this trigger:
CREATE OR REPLACE TRIGGER myTrigger
AFTER INSERT OR UPDATE OF aField ON myTable
DECLARE
myVariable NUMBER(2);
BEGIN
SELECT COUNT(keyColumn) INTO myVariable
FROM myTable
WHERE TO_CHAR(myTableDate,'mm') = (SELECT TO_CHAR(SYSDATE,'mm') FROM DUAL);
IF myVariable > 4 THEN
RAISE_APPLICATION_ERROR(20605, 'Here is an error.')
END IF;
END;
Every time the trigger is executed, this error happens:
ORA-06502: PL/SQL: numeric or value error: number precision too large
ORA-06512: at line 10
How do I resolve this problem?
Thank you.

Thank you.Are you sure the code you posted is what's actually running?
I would expect the missing semicolon after:
RAISE_APPLICATION_ERROR(20605, 'Here is an error.')to keep this from even compiling.
Error numbers are supposed to be negative. That will cause a run-time error when you try to raise the error.
This isn't actually an error, but there's rarely a need to use dual in PL/SQL.
WHERE TO_CHAR(myTableDate,'mm') = (SELECT TO_CHAR(SYSDATE,'mm') FROM DUAL);can also be done this way:
WHERE TO_CHAR(myTableDate,'mm') = TO_CHAR(SYSDATE,'mm');Actually, the condition above would work even outside of PL/SQL.

TS3376 I had my iphone set up to be tracked as registered with iCloud and it had been using it for a year one day it said no devices registered and stopped working why???

I had my iphone set up to be tracked as registered with iCloud and it had been using it for a year today it said no devices registered and stopped working even though i tracked the selected iphone 4 device an hour earlier why did it do this???

So basically the phone I was tracking was working an hour earlier it had no signal at times when it did pick up a signal it located it easily but an hour later the message came up no devices registered when my friend returned home I Checked the device I was tracking to make sure find my iphone was on but it was off and my friend didnt turn it off so my question is why did it turn itself off???
Confused?

Error in sql server with a trigger (I want to display a customize message, when the user left a blank field or null) How can I do?

How I display a customize message(with a trigger)when a user left a blank field? I want to the stop the insert statament if the user left the status field in blank. I create a trigger but now I can't enter a row, i used an instead trigger
too but doesn't work. I want to display a customize message when the user left the
status field in blank or null.
I have the following code:
CREATE TRIGGER [dbo].[BLANKFIELD]
ON [dbo].[Status]
FOR INSERT
AS
BEGIN
IF (SELECT COUNT(*) FROM inserted WHERE Status IS NULL) =1
PRINT 'Please Fill the Status field is required'
Rollback;
END

I agree with other comments that you should do this with specifying that the column is NOT NULL to prevent it from being NULL and a constraint if you don't want it to be blank (spaces or the empty string - note that the empty string is not the same thing
as NULL).
But for completeness, the reason your trigger does not ever allow you to enter a row is the code
IF (SELECT COUNT(*) FROM inserted WHERE Status IS NULL) =1
PRINT 'Please Fill the Status field is required'
Rollback;
Since you don't have a begin/end block after IF, the only conditionally executed statement is the one immediately following the IF (that is the PRINT). So the Rollback is always executed whether or not the IF is true and so all updates are rejected.
So if you were to do this in a trigger you could do something like the following
CREATE TRIGGER [dbo].[BLANKFIELD]
ON [dbo].[Status]
FOR INSERT
AS
BEGIN
IF EXISTS(SELECT * FROM inserted WHERE Status IS NULL)
BEGIN
PRINT 'Please Fill the Status field is required';
Rollback;
END
END
(As José noted, there can be more than one row in the inserted pseudo table, so you don't want to test whether the COUNT = 1, instead just whether one or more rows exist where the Status is null. If you want to prevent Status is NULL, or all
spaces, or the empty string, then your IF statement would be
IF EXISTS(SELECT * FROM inserted WHERE ISNULL(Status, '') = '')

I'm Using home sharing and there are 156 tracks I can't import because these tracks were purchase with a diff account. How could I import them in my new computer

Authorise the new computer to the older account. Can you do the transfer now?

Is it possible to start a PCI4472 and a PCI-MIO-16E-1 simultaneously using an analog trigger (with pre-trigger)?

I would like to start several PCI 4472 and a PCI-MIO-16E-1 simultaneously. All boards are connected via a RTSI cable.
My program works fine if I use software trigger, or an analog trigger from a PCI4472 channel. However, the analog trigger works only when I set pre-trigger (or pre-scan) to 0.
Is it possible to start a PCI4472 and a PCI-MIO-16E-1 simultaneously using an analog trigger (with pre-trigger)?
Thanks.

Hi, Bill
I think it is possible to set more than 38 pre-trigger scans on a single 4472 card. I've done this before. You can verify this by running the Labview example "Acquire N - Multi-Analog Hardware Trig.vi" which comes with LabView.
What I try to do but without success/luck so far is to start data acquisitions of several 4472 cards and a PCI-MIO-16E-1 card using an anlog trigger (with pre-trigger).
Thanks for your help.
Ian
