Triggers in pl/sql

hi
how to saw triggers output in pl/sql database?

Actually, you CAN see the output from dbms_output from a trigger, as long as the DML that causes the trigger to execute is run from a tool that can see dbms_output. For instance, suppose I have a BEFORE INSERT ROW trigger on EMP that does dbms_output.put_line('row inserted'); Then, if I execute the following in SQL*Plus:
set serveroutput on
insert into emp(empno,name) values(3000,'FLACK');I'll see:
row insertedbefore SQL*Plus says "Inserted 1 row."
However, dbms_output is not the best way to see what is going on inside your triggers, or to keep an audit trail. You don't see the output until after the client gets back control, and you need a dbms_output aware client, like SQL*Plus, TOAD or SQL Developer. Try calling a logging package that puts logging information into a table, or an external file instead. One such package is [Log4PlSql|http://log4plsql.sourceforge.net/], but this isn't the only one around.

Need urgent HELP in Triggers in PL/SQL

Hi all,
I am a noob in the db... i just started studying the PL/SQL.
i need ans to the below problem .. PLZ HELP
I had a table named employee with e_name,e_no,skill and payrate..
i need a trigger for the following
Updation is possible on the employee table if payrate is greater than the existing payrate and skill = ‘Chef’

NULL;
END;
but its showin the error tht when condintion cant be used with INSTEAD OF ...
Is their any other way i can create a trigger for this
PLZ HELP

Unable to see packages / triggers etc in SQL Developer 3.1.07

Hi
The user has SELECT_CATALOG_ROLE role granted but still cannot see packages of other users.
Is there anything else I need to grant to this user in order that it may have visibility?
Can't see package body in SQL Developer version 3.1 covers it to a point but I need more please.
Thanks.
This user has SELECT AND TABLE and CREATE SESSION.
When I run this on the database connecting as this user I get rows returned which tells me its a SQL Developer thing?
select text from dba_source where name like '%a_package_name%';
Which could also mean I need to reinstall the damn thing doesn't it?

Hi,
The SELECT_CATALOG_ROLE should be sufficient as far as privileges go. I cannot recall at the moment, but there may well have been a bug or two fixed between 3.1.07.42 and 3.2.20.09.87 that solves this. Please try upgrading.

Would RollBacks For Stateless Session Beans work In case of Stored Procedures or Triggers Written in Oracle PL/SQl

          We are writing a J2EE application and using Weblogic 5.1 on Unix machine. We are
          considering writing some Stored Procedures or Triggers on Oracle DBMS. Hence our
          Stateless Session Beans / Data Access Objects (DAOs) would be calling those stored
          procedures, which would reside on Oracle 8.1.7 (on Windows 2000). (These Data
          Access Objects are running under the umbrella of a Stateless Session Beans). We
          are using WebLogic's Connection Pooling.
          Our question is: Would we get reliable rollbacks from our stored procedures. I
          mean would the Transaction Management process of the EJB container work. Remember
          the SQL is written in the Database (Oracle in this case) in the form of Stored
          Procedures / Triggers through PL/SQL.
          Any ideas or tips would help.


          I would agree with Cameron Purdy. Be very cautious to use Oracle specific
          Triggers / Stored Procedures. Consider following, (apart from what he said):
          1. Unreliable behaviour of the Oracle JDBC drivers, specially 8.1.6 family..
          (You may visit the Oracle's web site and see the newsgroups for the JDBC drivers).
          This is enough of a reason to stop right there.
          However for interest sake you may consider following issues:
          2. By use of Oracle specific Triggers / SPs the application will not be portable.
          Vendor Lock In. Remember your choice for J2EE compliant Server (WebLogic in this
          case). The whole purpose would be defeated by going for this option.
          3. There are issues related to the extensibility of the application. I have
          my reservations and would hold my breath on two phase commit protocol transactions
          being reliable in this scenario.
          Have fun...

SQL*Loader and DECODE function

Hi All,
I am loading data from data files into oracle tables and while loading the data using SQL*Loader, the following requirement needs to be fulfilled.
1) If OQPR < 300, RB = $ 0-299, SC = "SC1"
2) If 300 < OQPR < 1200, RB = $ 300-1199, SC = "SC2"
3) If 1200 < OQPR < 3000, RB = $ 1200-2999, SC = "SC3"
4) If OQPR > 3000 USD, RB = > $3000, SC = "SC4"
Here OPQR is a field in the data file.
Can anyone suggest how do we handle this using DECODE function? Triggers and PL/SQL functions are not to be used.
TIA.
Regards,
Ravi.

The following expression gives you different values for your different intervals and boundaries :
SIGN(:OQPR - 300) + SIGN(:OQPR - 1200) + SIGN(:OQPR - 3000)

How to delete the Table Contents before inserting records into SQL table ?

Hello Experts,
I have a scenario where in I have to Pick up some records from SAP RFC & insert into SQL table.
i know how to do this scenario but the proble with this is before inserting we first have to ZAP the SQL table & insert a new records. One more twist is The Triggering is happening from SAP side with Sender RFC. If this would have been from SQL Side i could have written a Stored Procedure/ Trigger & could have called this before the SENDER JDBC communciation channel picks up the Triggering event from SQL side.
So how to do this scenarioin XI, First deleting all the Records of SQL table & then inserting the new reocrds. without using the BPM.

Umesh

hi umesh,
you can achieve this by writing SQL query in message mapping level..

Is there a way to create a Cascading ComboBox populated by an SQL/SDK query to a table? Referenced Lists too hard to maintain.

Background:
I’m looking for an alternative to using referenced Enum (aka Lists) for “dropdowns” (aka “ComboBoxes”) in the forms.
The reason for looking for an alternative mechanism for drop-downs was that using referenced Enums
ran into issues when the List items in the enum were to be updated:
The SCSM Console refuses to allow for the deletion of the referenced
Enum MP when there are other MPs referring to it.
The SCSM Console doesn’t allow the editing of a sealed Enum MP’s List items.
One has to hand-add new list items to the Enum MP’s XML.
Importing that new Enum MP over the old one causes views to not show data for the changed Enum.
The Customer wants the dropdown choices to be dynamically updated.
The Customer also wants this to be user-friendly “for the masses”, meaning that hand-editing XML and tinkering with the SCSM Console is undesirable.
We had enumeration lists with hundreds of choices, making hand-entry, using the SCSM Console, inordinately lengthy, error prone, and, frankly, tedious.
What I’m looking for:
The deeper requirements implied in these three Use Cases below are:
The system has to be easily maintainable.
The system has to reflect the latest changes in data.
The system has to be usable by “the masses”.
Large sets [200+] of choices have to be machine importable.
[Note: one reason why enums are not desirable is that we have had
hundreds of choices to add and a manual approach was not feasible]
Not as a prescription for a solution, but as a way of showing what I am looking for through an example-that-says-more-than-a-thousand-words: I want to implement the Service Manager usage-equivalent of a
“Cascading Dropdown” (aka “Cascading ComboBoxes”) instead of using Enums. It doesn’t have to use
Cascading Dropdowns but allow for the back-end ease-of-use that comes with it.
Use Cases:
Use Case 01: A User wants to edit the contents of a Windows Computer CI record.
Say that I want to change the field Business Unit and its associated field
Customer
You pick one element from a list of Business Unit choices.
The act of clicking on that field triggers a SQL search through a table of all current customers and populates the dropdown for the field
Business Unit.
Say, for the sake of an example, you pick the Business Unit “Accenture AO”.
The act of chosing “Accenture AO” triggers another SQL search through a table to find all
Customer values that belong to the Business Unit “Accenture AO” and that filtered set is used to populate the dropdown for
Customer.
The user chooses “Planet Express”.
The act of chosing “Planet Express” triggers a final SQL search through a table to find what the two-letter code is for “Accenture AO” + “Planet Express”, say “PE”. That value is used to set a
hidden field.
Use Case 02: Maintaining the tables used to populate Business Unit and
Customer lists
Say I’m an Admin who wants to update Business Unit and Customer
lists as there have been the creation of a new Business Unit “Accenture Galactic” and there have been new Customers ”Klingon Karrier”, “Romulan Relaxair”, and “Federation Fun” and, say,
two-hundred other Customers, with their two-letter codes “KK”,”RR”,”FF”…etc…etc..etc… respectively.
I open a table editor for Business Unit and Customers.
I have, say a CSV that has the Business Unit, Customer, and Code field and 200+ records
I import using some automated mechanism the 200+ records.
Use Case 01-B: A user immediately has their choices updated.
Say that I want to change the field Business Unit and its associated field
Customer
You pick one element from a list of Business Unit choices.
The act of clicking on that field triggers a SQL search through a table of all current customers and populates the dropdown for the field
Business Unit.
Say, for the sake of an example, you pick the Business Unit “Accenture Galactic”.
The act of chosing “Accenture Galactic” triggers another SQL search through a table to find all
Customer values that belong to the Business Unit “Accenture Galactic” and that filtered set is used to populate the dropdown for
Customer.
The user chooses “Federation Fun”.
The act of chosing “Federation Fun” triggers a final SQL search through a table to find what the two-letter code is for “Accenture Galactic” + “Federation Fun”, say “PE”. That value is used to set a
hidden field: “FF”

consider
http://blog.scsmsolutions.com/2011/08/create-custom-user-control-for-scsm-2010/ and http://social.technet.microsoft.com/Forums/en-US/09813153-a4d0-4bce-8d28-3ccc63bd72a1/resources-for-adding-custom-wpf-controls-to-service-manager-forms?forum=customization
As for the Data Typing, the class property would be a String type, which maps to NVARCHAR in SQL, so any unicode characters, including XML (i'd recommend keeping it below 4000 for performance reasons). look to how the UserInput control works in Service Requests.
I would recommend a class extension woth a single string property to store the data on the windows computer class, and a separate stand-alone class to store your "options". no relationship should be implied.

Interesting issue with Logical Standby and database triggers

We have a Logical Standby that each month we export (expdp) a schema (CSPAN) that is being maintained by SQL Apply and import (impdp)it to a 'frozen copy' (eg CSPAN201104) using REMAP_SCHEMA.
This works fine although we've noticed that because triggers on the original schema being exported have the original schema (CSPAN) hard-referenced in the definition are imported into and owned by the new 'frozen' schema but are still 'attached' to the original schema's tables.
This is currently causing the issue where the frozen schema trigger is INVALID and causing the SQL Apply to fail. This is the error:
'CSPAN201104.AUD_R_TRG_PEOPLE' is
invalid and failed re-validation
Failed SQL update "CSPAN"."PEOPLE" set "ORG_ID" = 2, "ACTIVE_IND" = 'Y', "CREATE_DT" = TO_DATE('22-JUL-08','DD-MON-RR'),"CREATOR_NM" = 'LC', "FIRST_NM" = 'Test', "LAST_PERSON" ='log'...
Note: this trigger references the CSPAN schema (...AFTER INSERT ON CSPAN.PEOPLE...)
I suspect that triggers on a SQL Apply Maintained schema in a Logical Standby do not need to be valid (since they do not fire) but what if they reference a SQL Apply schema but are 'owned' by a non-SQL Apply schema? This trigger references a SQL Apply table so it should not fire
This is 10gR2 (10.2.0.4) on 64 bit Windows.
Regards
Graeme King

OK, I've finally got around to actually test this and it looks like you are not quite correct Larry in this statement...
'Since this trigger belongs to a new schema that is not controlled by SQL Apply (CSPAN201105) it will fire. But the trigger references a schema that is controlled by SQL Apply (CSPAN) so it will fail because it has to be validated.'
My testing concludes that even though the trigger belongs to a schema CSPAN201105 (not controlled by SQL Apply) and references a schema controlled by SQL Apply - it does not fire. However it DOES need to be valid or it breaks SQL Apply.
My testing was as follows:
Primary DB
Create new EMP table in CSPAN schema on Primary
Create new table TRIGGER_LOG in CSPAN schema on Primary
Create AFTER INSERT/UPDATE trigger on CSPAN.EMP table (that inserts into TRIGGER_LOG table)
**All of the above replicates to Standby**
Standby DB
Create new table TRIGGER_LOG_STNDBY in CSPAN201105 schema on Primary
Create new trigger in CSPAN201105 schema that fires on INSERT/UPDATE on CSPAN.EMP but that inserts into CSPAN201105.TRIGGER_LOG_STNDBY table)
Primary DB
Insert 4 rows into CSPAN.EMP
Update 2 rows in CSPAN.EMP
TRIGGER_LOG table has 6 rows as expected
Standby DB
TRIGGER_LOG table has 6 rows as expected
TRIGGER_LOG_STNDBY table has **0 rows**
Re-create trigger in CSPAN201105 schema that fires on INSERT/UPDATE on CSPAN.EMP but that inserts into CSPAN201105.TRIGGER_LOG_STNDBY table) **but with syntax error**
Primary DB
Update 1 row in CSPAN.EMP
TRIGGER_LOG table has 7 rows as expected
Standby DB
SQL Apply is broken - ORA-04098: trigger 'CSPAN201105.TEST_TRIGGER_TRG' is invalid and failed re-validation

Trigger problem on Sql Server with linked server to Oracle

Hi All,
I have a simple insert trigger on Sql Server 2005, it uses linked server to Oracle.
like that ;
USE [YTM08]
GO
SET QUOTED_IDENTIFIER ON
GO
ANSI_NULLS ON
go
ANSI_WARNINGS ON
CEATE TRIGGER [dbo].[YTM_TBLSTSABIT_I]
ON [dbo].[TBLSTSABIT] FOR INSERT
AS
BEGIN
INSERT INTO YTM_ORACLE..SECTOR.STOCKS
stock_name,
stock_code,
insert_date
SELECT
SBT.STOCKNAME,
SBT.STOCKCODE,
GETDATE()
FROM INSERTED SBT
END
The YTM_ORACLE is a linked server and it's provider is OraOLEDB.Oracle.
Trigger does not works for that linked server but other triggers for local
sql server works fine...
I get this error from sql server
'Heterogeneous queries require the ANSI_NULLS and
ANSI_WARNINGS options to be set for the connection. This ensures consistent query semantics. Enable these options and then reissue your query.'
Does someone know how to solve this issue the right way?
Thanks in advance.
Thanks !
Adam

Hi Lars,
Thanks for the data. I've already read this note and configure all this parameters. But when I'm executing the Create Source System in the BI system the process dies.
If I look into the logs I see this:
M call semaphore clean-up function ...
M ***LOG Q0E=> DpSigGenHandler, Exception (c06d007e) [dpnttool.c 432]
That's the reason why I start guessing about other possible problem.

Retrieving triggers messages

Hi! I came across this problem the other day. I have created triggers in my SQL. The triggers are stating appropriate message for any worng data entry. But I cannot catch this message from front end either by servlet or swing. Can any of you please help me out?
I really really appreciate any help
Thanks in advance.

I don't know how mySQL does it (since when does mySQL support triggers btw).
SQL Server stores those messages (created using PRINT) in the Warning object returned from the connection (or statement I can't remember)
For Oracle you would need to read messages written with the DBMS_OUTPUT package.

Can sql*forms version 3 run in oracle 8 or higher database

I support an application developed many years ago with sql forms version 3 - has .inp files for the source code. It is currently running on a 7.3.4 database. My bos has asked why the database cannot be updated to a newer version. It is my understanding theat newer versions of the database do not support the types of triggers used in sql*forms. is this correct?

Exceptions with triggers

Hi, i am working on the triggers for a SQL server database.
There are in some cases where more than 2 triggers are fired and the message they sent would send an exception to the Java prog.
However, the exception received is always the same type and thus only the first trigger is received properly by my java app.
What should i do to resolve this problem?
Eg:
try
rs=executeUpdate("Update something set one=1");
}catch(Exception e)
//Should i loop here to keep retrieving messages? If i got more than 1 trigger fired.

Only one SQLException can be thrown. It may be that this exception somehow contains a set of messages, in which case you would have to write a loop to get those messages. But I doubt it. Why not try it and see what happens?
