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 > Table flashback to before drop
Create some table: CREATE TABLE MYCUSTOMERS( ID_CUSTOMER NUMBER(4) NOT NULL, CITY VARCHAR2(20 BYTE) DEFAULT 'MISSING!', LAST_UPDATE DATE DEFAULT SYSDATE NOT NULL ) / Insert some dato into the table: INSERT INTO MYCUSTOMERS(ID_CUSTOMER,CITY) VALUES(3,'NEW YORK'); INSERT INTO MYCUSTOMERS(ID_CUSTOMER,CITY) VALUES(4,'BERLIN'); INSERT INTO MYCUSTOMERS(ID_CUSTOMER,CITY) VALUES(5,'ROME'); INSERT INTO MYCUSTOMERS(ID_CUSTOMER,CITY) VALUES(6,'PARIS'); INSERT INTO MYCUSTOMERS(ID_CUSTOMER,CITY) VALUES(7,'LONDON'); COMMIT; Then drop the table:
SQL> drop table MYCUSTOMERS;
Now get the table back using BEFORE DROP:
SQL>flashback table MYCUSTOMERS TO BEFORE DROP;
Dependig oracle initialisation parameters and time passed by, you should get the table back:
SQL> select * from MYCUSTOMERS;
