A User Agent, like a web browser, uses HTTP to request a HTML document
Php Funzione mail()
In programming the danger of exploring the small details of coding is that you get obsessed with every line of code you write, thereby greatly reducing productivity.
In general, is not worth obsessing over code. On the other hand you should code with deliberation and intent. Steven Feurstein Oracle Magazine July /August 2004 A User Agent, like a web browser, uses HTTP to request a HTML document

Home >Oracle > Auditing for wrong sql
Simple and quick example auditing on insert, tested on Oracle 10.2.0.1.0. The context: I have some batch jobs and ETL application cannot insert data on a table. Programmers get Oracle errors such ORA-01722 but unfortunally cannot print out the wrong sql statements and so they have problem debugging. Programmers asked for DBA help. Among various Oracle tools, I pick up auditing tecnique. Auditing can be traced on files (OS) or on tables (DB, DB_EXTENDED). In this case I choose on tables. First, I make sure the Oracle initialisation parameters are properly setted, if not, I need to modify the parameter file and restart the db, in fact these parameter are not dynamic. audit_trail=DB_EXTENDED audit_sys_operations=TRUE audit insert on test.t1 by access whenever not successful; I use the clause access instead of session/font>, I want intercept any single statement on the table, and whenever not successful is precisely what I am looking for. Now that's all set, I try this basic test. Schema TEST got this simple table t1(n number,d date); Logged as TEST I execute the following insert statements: insert into t1 values(90,sysdate); insert into t1 values('aaa',sysdate); insert into t1 values(110,sysdate); insert into t1 values(110,to_date('2006-23-01','yyyy-mm-dd')); Lines 2 and 4 are obiously not correct (string instead a number, incorrect month). Logged as dba, I do aspect to find these incorrect statements on AUD$ table and in the dba_audit_trail view. So I run a query like this: select timestamp, userhost, terminal,owner,obj_name,action_name,returncode,sql_text from dba_audit_trail;
So it works as expected and I am ready for the serious work: incorrect insert actions have been recorded on the audit table. When I am over with audititing, I disable the audit: noaudit insert on test.t1; I disable the init parameters. To delete the sys.Aud$ table records, just delete them.
