Getting all_tab_columns.data_default in a ddl trigger

Under 10.1.0.3 I'm working on an AFTER CREATE or ALTER on DATABASE system trigger, and I'm querying all_tab_columns in the trigger body. It seems that if the trigger fires in response to DDL that modifies a column's default value, then all_tab_columns.data_default is giving me the column's old default. I want to get the current default value. If I create the table or add a column, then, in the resulting fire of the system trigger, all_tab_columns.data_default seems to be correct.
Is this documented behavior? Should I be looking somewhere (or somewhen) else for the column default?

Thanks.
I tried working around this by putting my code into a procedure, and then using the DDL trigger to create a job that runs the code. My idea was to defer the all_tab_columns query until after the DDL trigger was done, and thus get a clean look at the data dictionary.
I put what looks like the appropriate dbms_scheduler calls into the trigger, but when I then execute DDL to fire the trigger I get "ORA-04092: cannot in a trigger"
The doc for this error number says that I am trying to commit or rollback in a trigger, but I'm not explicitly doing that. Also, the error message is supposed to have either the word "commit" or the word "rollback" in the message to tell me what I am doing. Instead, though, the error message just has a space there.
Maybe I'll start a TAR and see if 10.1.0.3 can get appended to the growing list of versions tied to this bug.

How to get added columns in the after DDL trigger?

As title, I want to get information, like name/type/.., about the added columns by sql statement "alter table *** add (***)" in the after ddl trigger. But looks like dba_tab_columns view doesn't include the added columns.
Thanks

Hi
Hi try other versions of the trigger like
create or replace trigger addl_trigger

m_user1:=ora_login_user;
m_owner:=ora_dict_obj_owner;
m_type:=ora_dict_obj_type;
m_name:=ora_dict_obj_name;
if (m_type='TABLE' and m_event='ALTER')
then
          execute immediate 'select count(*) from dba_tab_columns where owner=:1 and table_name=:2' into m_cnt
          using m_owner,m_name;
          insert into log values (m_cnt);
          dbms_output.put_line('->'||m_cnt);
          OPEN m_cur FOR 'select c.name from sys.col$ c, sys.obj$ o, sys.user$ u where o.obj# = c.obj# and o.owner# = u.user# and u.name=:1 and o.name=:2' using m_owner,m_name;
          LOOP
                    FETCH m_cur INTO m_stmt;
                    EXIT WHEN m_cur%NOTFOUND;
                    insert into log values (m_stmt);
                    --dbms_output.put_line(m_stmt||'**************');
                    END LOOP;
end if;
but all versions continue to insert only the already existing columns. I think that Oracle actualize the dictionary first after this system event.

DDL-trigger can't use select on table affected by DLL-statement?

Hi all,
my situation
I have a DDL-trigger that gets executed after every alter-statement. The trigger reads some information from the table CHNGHIS_TAB. The trigger works fine for all the tables except for CHNGHIS_TAB. When I try to add a column to this table, I get the following error (translated from german, I don't know, if the message is exactly the same in english):
SQL> alter table chnghis_tab add (test varchar2(254));

    select count(tabname) into counter from chnghis_tab where upper(tabname) = tablename;
    if counter = 0 then
        return;
    end if;
    /* call the procedure to generate the logging trigger */
    generateLogTrigger(tablename);
end;Thanks for your help =)

It looks like you are getting an ORA-00600 error. You should contact Oracle support.

Getting iteration number in row level trigger

Hi. Is there a way to get iteration number in row level trigger? Or to access data inserted in statement level trigger from row level trigger (statement level trigger are supposed to be executed before row level triggers but I cannot access them).
I'm using Oracle 10g.

My oracle version:
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bi
PL/SQL Release 10.2.0.4.0 - Production
CORE 10.2.0.4.0 Production
TNS for 64-bit Windows: Version 10.2.0.4.0 - Production
NLSRTL Version 10.2.0.4.0 - Production
And business problem is like this:
I need to have two log tables for some tables in my database:
First log table is a statement level log. After insert or update or delete it should get one new row with mentioning date, time, sid, query type and some additional information.
Second table should include all columns from table logged, date, time, sid and operation type.
The problem is, I need exact the same date and time for each row in both log tables.
Someone said that sysdate should return same value for query execution time. But it have nothing to do with triggers fired on this query.
So you may say that I'm curious about getting exact same date and time for one statement level trigger and for each execution of row level trigger.

Can someone let me know what should be done? I have production issues which should be resolved.

Hi,
The problem happens when someone creates a table in their procedure and drops it off at the end of the procedure, the JOB which is in the queue when it executes, it cannot find the table and the jobs are failing.Seems more like this is the problem:
SELECT temporary
INTO n_temp
FROM dba_tables
WHERE table_name = v_object;If that would not throw NO_DATA_FOUND, there would be no need for the dbms_job.
Seems safe to remove, you are not using n_temp and if it raises no_data_found you are doing nothing.
Also, these are not necessary
SELECT ora_dict_obj_owner INTO v_owner FROM DUAL;
SELECT ora_dict_obj_name INTO v_object FROM DUAL;
SELECT ORA_DICT_OBJ_TYPE INTO v_object_type FROM DUAL;You can use System Events in PL/SQL
Why this comment?

How do you get a list of all the trigger DDLs?

I want to get a list of all the DB trigger DDLs of owner 'ABS'. I want to do it using 1 SQL statement.
This is what I ran:
SELECT
TO_CHAR(DBMS_METADATA.GET_DDL('TRIGGER', TRIGGER_NAME, 'ABS'))
FROM
ALL_TRIGGERS
WHERE
OWNER = 'ABS';
I get this error: [1]:
(Error): ORA-22835: Buffer too small for CLOB to CHAR or BLOB to RAW conversion (actual: 4414, maximum: 4000)
Then I looked up in the web and they ask to use DBMS_LOB.SUBSTR instead. So I do that:
SELECT
DBMS_LOB.SUBSTR(DBMS_METADATA.GET_DDL('TRIGGER', TRIGGER_NAME, 'ABS'), 32767, 1)
FROM
ALL_TRIGGERS
WHERE
OWNER = 'ABS';
Now I get this error:
[1]: (Error): ORA-06502: PL/SQL: numeric or value error: character string buffer too small ORA-06512: at line 1
Looks like you cannot show more than *4000* chars. There are 43 triggers whose DDL is more than 4000 chars long.
Why is this?
How can I solve my problem?
Edited by: Channa on Feb 16, 2010 9:45 PM

Herald, fantastic news. SET LONG did the trick.
But I had to put a very big value. 32000 was not enough. Otherwise some of the triggers (big ones) got cut off.
This is my complete code which did it.
SPOOL F:\Channa\zz_zzTemp\Binuka\OutPut.txt
set trimspool on
set pages 0
set long *1000000000*
set linesize 32767
SET TERMOUT OFF
SELECT DBMS_METADATA.GET_DDL('TRIGGER', TRIGGER_NAME, 'ABS')
FROM ALL_TRIGGERS
WHERE OWNER = 'ABS' AND trigger_name NOT LIKE 'BIN$%'
SPOOL OUT
THANKS A LOT. REALLY APPRECIATE IT.
P.S: I had to include the NOT LIKE 'BIN$%' in the where clause because otherwise I got this error:
ERROR:
ORA-31603: object *"BIN$cqXDSqghrFngQKjAJAovgw==$0"* of type TRIGGER not found in

ORA-06512: at "SYS.DBMS_SYS_ERROR", line 105

ORA-06512: at "SYS.DBMS_METADATA", line 4333
ORA-06512: at line 1

Get old and new text of a VIEW at DDL trigger

Is it possible to get the old and the new text of a view at the DDL triggers

Hi,
Don't know regarding later Oracle versions but with 8.1.7.3.0 you cannot base system triggers on tables or views: Ora-30506.

A few comments.
Lets assume you run a delete statement that deletes 550 rows from your table. If your trigger is working then the very same statement would be stored 550 times. I think an BEFORE or better an AFTER delete STATEMENT level trigger would be the better choice. Why AFTER? Because if the delete operation fails, for example because of existing child records, then everything is rolled back anyway to the implicit savepoint just before the delete.
So to store the SQL statement the correct trigger would be an AFTER STATEMENT DELETE trigger.
Now what to store: You want the sql statement. You could try to find the cursor/currently running SQL. It might be tricky to separate that from the SQLs that you run to find this out.
It could even be possible to simply save all commands that are in your PGA/Cached cursor area. First find out yur session, then store the SQL_text (first 60 chars) for all the cursors in this session by using v$open_cursor or the first 1000 chars by using v$sql.
Here are a few views that might be helpful. v$session , v$open_cursor, v$sql, v$sqltext, v$sql_bind_data, v$sql_bind_capture, dba_hist_sqltext

Anyone been able to get OS Image Capture to remote trigger Canon EOS DLSR?

Hi
I am connecting my Canon EOS 50D DLSR to a MacBook using USB.
I am able to copy photos off the camera's memory card, however the built in OS X Image Capture software refuses to remote trigger the camera to take a picture.
I need to try get it working as being able to remote trigger the camera using the Image Capture software is a pre-requisite to using iStopMotion animation software which apparently uses the same Quicktime framework.
Thanks in advance.
Chris

iStopMotion fails to trigger the camera. I have been in contact with the developers and they say that iStopMotion uses the same Apple Quicktime framework as the OS supplied Image Capture software (which does have a Take Picture menu option)
So essentially if I can resolve the issue and get the Apple OS Image Software to trigger the camera it is a good indication that the issue is resolved and the iStopMotion software will also work.
I am using the Image Capture software to test the issue as my free demo license to iStopMotion has now expired and obviously I don't want to buy the software unless I believe it will work.
Any Canon EOS 50D DLSR owners out there who can test their camera with the Mac OS Image Capture Take Picture option?

Hi Azotov,
It looks like the DAQmx Base driver readme includes Mac OS X support for LabVIEW 8.5. Could you specify what hardware you are using?
I found one KnowledgeBase specifying that error code occurs when you try to use certain properties with certain devices. Of course, this would most likely occur every time you run the task, not 5% of the time.
Since I'm running Windows, it's a little difficult to see if you have DAQmx Base "Reset Device" functionality with that version of the driver. You might check if you can run that functionality before using your device, though.

How to get the SQL which invoked a trigger

Hi,
I have a table from which the rows are getting deleted without our knowledge.
To track this I've put a trigger on delete of this table. I want to know which SQL is actually invoking this Delete trigger so that I can capture it inside the trigger and log it somewhere so that I can analyze from where this SQL is fired.
Please let me know if any one can help me regarding this.
Thanks,
Makrand

If possible try and explore the FGA (Fine Grained Auditing) option . You may not need to create any triggers on the table and look up V$ views.
Instead, define a RULE on the table. FGA will track the DML operation performed based on the RULE you defined
i.e Consider a policy/Rule defined on the table TEMP as follows.
begin
dbms_fga.add_policy (
object_schema => 'SCHEMA_NAME',
object_name => 'TEMP',
policy_name => 'TEMP_DELETE',
audit_column => NULL,
audit_condition => NULL,
statement_types => 'DELETE'
end;
DBA_FGA_AUDIT_TRAIL view can then give you all the information required.
You will need to have execute privilege on DBMS_FGA package.
FGA will help if you are on 10g. In 9i it has a limitation – It can only use SELECT and not the other DML operations. So if you are on 9i, follow what the other members have mentioned ‘cause FGA will not be of much help to you.
I[b] have not used this feature - Maybe you can give it a try and update the forum members. The limitation using FGA is that Auditing on the table is still enabled when ROLLBACK statement is issued.
My preference will be using this feature instead of writing triggers on the table.
Try using Google search and get more info on the FGA.. Good Luck !
