View 20 RepliesI have to write two triggers on same table for auditing different columns of different users(may be different modules).
I will have an audit table in which i will insert data such as (user_id,module_id,column_name,old_col_val,new_col_val,timestamp)
Now different users from different modules will update the data on same table may be same columns from different front end forms!
If we write directly, we will not be able to know which column is updated by which user.
My question is in this case how can we control the triggers to raise differently?
Im going to create a trigger(insert or update) for a table A, when it fires inserted or updated columns are should be insert or update into another table say table B, one column(Processed_time) in table B where its value will be by subtracting two columns in table A(response_time,Submission_time) all are timestamp type.
How to update(Processed_time) in table B by subtracting above two columns in table A.
I have rather large compound triggers that I discovered were not firing this morning, so I created a simpler compound trigger to test:
CODECREATE OR REPLACE TRIGGER "test"
FOR INSERT OR DELETE OR UPDATE OF KI_NM ON CHEMAXON.CB1ASSAYS
REFERENCING OLD AS OLD NEW AS NEW
FOR EACH ROW
ENABLE
[code]...
It's just not firing. The tables are all in the owner's schema (who has DBA rights). My Google-fu is failing me, and I'm not sure how to start troubleshooting general trigger failure.
The trace directory is full of trc files with the text below:
--------Dumping Sorted Master Trigger List --------
Trigger Owner : INPUT
Trigger Name : CUS_TST
--------Dumping Trigger Sublists --------
There is like a file generated every minute, and i cant stop it from happening.I have tried setting the trace_enabled parameter to FALSE but no success.
I have column names stored in a table(say t1).
Inside a trigger I have to dynamically get the : old. values for only these columns.
This I need because during update trigger on a table (say t2) I am supposed pickup the coumn names stored in t1 and get the : old values of only these columns to insert into a new table .
I am creating triggers for audit operation when any insert/update/delete happens on a table automatically.Now i need the same functionality in procedure.
My requirement is to create procedure for all those triggers.
There are two servers A and B ,and i am maintaining one table suppose table1 and another table suppose table2 , DML triggers are made for both of these tables.The action of DML trigger is that the movement we are inserting values , suppose a table1 on server A so automatically the same set of value in table2 on server Bso my problem is that the movement i inserted value on table1 on server A ,
the same set of values were inserted into table2 of server B and as the values were inserted intotable2 , the same set of values were inserted into the tabld1 because of the trigger. How to stop the non ending loop which occurs due to the simultaneous firing of triggers and insertion of same records into both the table endlessly...
version :---Personal Oracle Database 10g Release 10.2.0.3.0 TNS for 32-bit Windows: Version 10.2.0.3.0
I'm having a bit of a problem getting the syntax of a trigger right. Unfortunately, I have no DBAs locally, I use some third party software, and for reasons beyond my understanding, I have been told to use triggers, and not stored procedures, so I'm running with it.
The set up:
STRUCTURES table: contains several columns, one of which is the unique ID column.
ASSAY table: contains several rows, also with the same ID column, but can have more than one row per ID (several assays per compound). One column is XC_ASSAYS.
The idea of the trigger is basically: When a row in the ASSAYS table is updated, pull out the ID of the row, then calculate the average of the XC_ASSAYS columns for those rows, and report it to the STRUCTURES.XC_ASSAY column for that row ID.
My best attempt thus far results in compilation errors.
CREATE TRIGGER INHIB_W_ALA_TR
AFTER INSERT OR UPDATE ON ASSAYS
FOR EACH ROW
BEGIN
UPDATE STRUCTURES SET XC_ASSAY = (SELECT AVG(XC_ASSAY) FROM ASSAYS WHERE ASSAYS.ID = :NEW.ID) WHERE STRUCTURES.ID = :NEW.ID
END;
/
The resulting errors are:
LINE/COL ERROR
-------- -----------------------------------------------------------------
2/1 PL/SQL: SQL Statement ignored
2/190 PL/SQL: ORA-00933: SQL command not properly ended
12/0 PLS-00103: Encountered the symbol "end-of-file" when expecting
[code]...
I don't understand some of the errors, such as why line 2 SQL is ignored (it seems correct?), or I'm supposed to properly terminate the trigger (I've read ; and /, but I'm getting the end-of-file errors when I do so). Tried shuffling syntax and ' or " around - and I can't get it.The body SQL works when I replace :NEW.ID with an actual variable (such as 'NMP12'), but I'm not sure how to pass the ID variable from the updated row into the body. The ID is not updated, but other columns are.
I have a question about GG Sequence Replication and Triggers. My main database, which I would like to replicate on another server, is highly dependent on sequences for assigning surrogate keys to every row in every table in the application. I know that I need to add Sequence support to my source database (plus supplemental logging, etc), but I'm curious about the target database.
I do not anticipate allowing Read/Write access to this database - we are migrating from 10.2.0.4 (source) to 11.2.0.3 (target) on a new platform, and I want to keep the 11g database up-to-date with our production data until it is time to begin the actual conversion of our application. My thinking is that if I use the SUPPRESSTRIGGERS dboption in my Replicat session, this should take care of the use of the Sequences for assigning the surrogate key values, and the data should add to the tables normally without any intervention by the sequences/trigger combination. I know I will have to manually "correct" the sequences on my 11.2.0.3 database whenever I want to open this database up for use, but I have a script for this ready to go.
Also, in my source database, I am using Oracle Context indexes for generic name searching - this feature creates a number of DR$ named tables in the main application schema that I am replicating (approximately 50 of them). I am assuming that I should EXCLUDE these tables from the replication, as the context indexing should automatically update them as changes to the underlying data are applied via the replication of the indexed tables.
why when-mouse move,up,enter,leave are not working in oracle forms 10g except when-mouse-click and when-mouse-doubleclick on any items.
what i need to do to execute this triggers..
I am unable to understand why row level triggers cant be used in mutating tables.
If you need to update a mutating table, you could bypass these restrictions by using a temporary table, a PL/SQL table, or a package variable. For example, in place of a single AFTER row trigger that updates the original table, resulting in a mutating table error, you might use two triggers--an AFTER row trigger that updates a temporary table, and an AFTER statement trigger that updates the original table with the values from the temporary table.
can change the order of triggers in forms 6i . that means firing in form level?
View 4 Replies View RelatedHow to catch or store the sql statement that caused the trigger to fire in DMl Triggers.
View 11 Replies View RelatedI am working on a form, whose one block is query_find, so on clicking find button it will open another block.the find block contain 4 column and second block contain around 10 column.but the column present in find block are associated to standard tables and the column present in block-2 are from custom tables.there is a query which link those column.
I am not sure where to use that query, so that it will take input from the find block and then populate the result into the block-2.
Suppose if I have defined two triggers Key-next and When-validate-item on the same item.
If my key-next is going to fire first and When-validate-item laterhow can the validation happen if I write a code like go_item('XXXX') in my Key-next.Does it mean that if u write a code in key-next to jump to some other item, no validation takes pLace?

View 7 Replies View Related i've a problem regarding my code at line: 76. URL....
If i put a RAISE_APPLICATION_ERROR just before:
SELECT ID_GIOCATORE INTO CONTR_GIOCATORE2
FROM COMP_CONTR_GIOCATORE_PARTITA GC JOIN CONTRATTO C ON GC.ID_CONTRATTO = C.ID_CONTRATTO
WHERE GC.ID_PARTITA = :NEW.ID_PARTITA AND (C.ID_CASELLA = 28 OR C.ID_CASELLA = 12) AND C.ID_CASELLA <> :NEW.ID_CASELLA AND
[code]....
But if i put the RAISE_APPLICATION_ERROR just after this statement and before IF(CONTR_GIOCATORE2 IS NOT NULL AND CONTR_GIOCATORE2 = CONTR_GIOCATORE) THEN, nothing happens after the insert(that goes well) and the trigger doesn't do his job(insert,update etc). if i do that select, i got the no data found, so i put the exception to set the variable CONTR_GIOCATORE2 to NULL.
I recently stumbled upon a post for an undocumented golden gate procedure that I find VERY useful when repairing / simplifying spatial data as a DBA without causing user triggers to fire and do unnecessary work, etc. Anything with foo in the name must be good, right? ;-)
HINT: Oracle please make this a documented feature!
This will disable triggers – just for a session – no system wide changes or trigger mods needed! Yes, fire needs to be set to true - to disable the triggers from firing.
exec sys.dbms_xstream_gg.set_foo_trigger_session_contxt(fire=>true);
Note, you will need execute permissions on sys.dbms_xstream_gg first.See for more info: URL.....
May i know the triggers in forms 6i, which is applicable to all items,blocks and form.

View 2 Replies View RelatedTriggers for oracle database. What I am trying to do is copy original data from one table to another table prior to an update, insert, or delete occurring. Basically we are trying to keep a transactional history, with out having to restore the data. Here is what I have created to date, however it is not executing consistently.

I have the source tables having 10 columns. I want to track the delta changes of only 6 columns. In case of insertion/updation, that new record should be inserted into another DELTA table of different schema.While in case of deletion, A new row will be inserted into that DELTA table , with the value of the primary key and other columns populated with NULL values.
I have applied the concept of 'after trigger' specifying the columns names but it logic is not working properly. Its tracking the changes for other 4 columns also.
now i can log in but here i faced with another erorr, while i am creating a trigger it gives the following erorr:
SQL> ed

note: i tried and gave different names for the trigger, still it is the same.
I am looking at an existing utility which inserts data into configuration tables. The utility is fairly basic, you simply add the UPDATE / INSERT / DELETE sql commands to a .sql file, set up a few params in a .sh script in order to tell it which Database / Schema to run against and away it goes, doing some logging, etc on the way.
Most of the time this is fine. However there is one table that causes big performance problems. This large table holds rating data and it has two large triggers on it. It also gets updated quite a bit with new rating tariffs.
The triggers check that many fields are not null or are certain values... but they also check that dates of the rates do no overlap, etc. So, in short, they do a lot of work. I can see that these are the main performance obstacle. I have no ability to alter or disable these triggers, this is a core table supplied by the vendor and as such I cannot manipulate it.
So looking at the things I can change, what am I left with?... only the way I load the data..
I can consider using SQLloader in order to handle INSERTS or using the APPEND hint in order to perform a direct path insert rather than having individual INSERT statements.
I can try to ensure that my data is sorted along the same lines as the index on the table in order to ensure that I am updating the index nodes in as streamlined way as possible. I can improve performance still more, or even circumnavigate the drag of the triggers?
Is it possible to call procedures and functions in Database Triggers?
