update trigger in oracle on updating a column-40

Now I need that feature for the blobs too -but it seems it is very difficult. However, you can use a LOB in the body of a trigger as follows:- in regular triggers old values may be read but not written and new values may not be read nor written.- in 'instead of triggers', the:old and:new values can be read but not written.o dbms_lob.write (and other dbms_lob calls) do not fire a trigger -- people can and will change the value of a blob and you will not be able to detect it with a trigger.

In order to update a LOB, I might never issue an UPDATE. I am a DBA for a large development team, and just received some new ddl that has a table with 2 blob columns.

This question is Hello Tom-my requirement is When a record is inserted into ERR table, a post-event trigger will fire updating the D field to accept sys date (3 columns has to update in my original requirement).

I've written the below code, however after the record is inserted it's not being updated with sys date in D rather I got the mutating error. SQL insert into err(x) values(2);insert into err(x) values(2) *ERROR at line 1: ORA-04091: table ERR is mutating, trigger/function may not see it ORA-06512: at "TRIG_2", line 3ORA-04088: error during execution of trigger 'TRIG_2'SQL thank you very much for your help and suggestions.

If you are at the conference, drop into the Groundbreaker area and say Hello. I could not give a Blobfield in the trigger-observed Field List ... Greetings from Dresden, Andreas Näther Well, this is a sticky issue (i think we can solve it though).

Thus, one should NEVER create an UPDATE trigger on a BLOB column, since it isn't reliable.I would like to be able to populate a documents table using either mod_plsql or SQL*Loader and have the same results, but can't seem to figure out how to populate the above listed file attribute columns when I load from SQL*Loader.
