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 > Recyclebin checking and purging
Recyclebin allows you restoring table that have been dropped. In fact, if the init parameter recyclebin is ON you may restore a dropped table using flaskback table to before drop or flaskback table to SCN. Depending by initialisation memory parameter Oracle keeps the table in the recycle bin as long as it can. It is a DBA good practise empty periodically the recyclebin whenever it's positive there would be not need to restore the table and data dropped. Example, create table T1
create table T1 (n number);
insert into T1 values(1); insert into T1 values(2); insert into T1 values(3); commit; drop table T1; to check the status of recyclebin
col object_name format a18
col original_name format a10 col createtime format a14 col droptime format a14 SELECT object_name, original_name, space, createtime,droptime FROM user_recyclebin;
if you are using sqlplus you can also issue:
show recyclebin;
to empty recyclebin
purge recyclebin;
to drop a table without keep it temporally in the recyclebin to empty recyclebin
drop table mytable purge;
Recyclebin tables are:
As purge recyclebin deletes the schema objects, to purge all recyclebin in every schema in the whole database with dba privileges you need to issue purge dba_recyclebin : -- to purge all database objects in recyclebin SQL> conn sys as sysdba Enter password: Connected. SQL> purge dba_recyclebin; DBA Recyclebin purged.
