Create a shortcut to open an FTP site in Windows Explorer

Open My Computer by clicking the Start button, and then clicking Computer.
Right-click anywhere in the folder, and then click Add a Network Location.
This displays the Add Network Connection wizard. Click Next.
In the wizard, select Choose a custom network location, and then click Next.
Enter the name of the FTP site, with the full FTP:// in front of it, and then click Next.
To use a name and password, clear the Log on anonymously check box. Type a user name, and then click Next.

If you do not want the FTP site to open after you're done setting up the shortcut, clear the Open this network location when I click Finish check box. Click Finish. A shortcut to the FTP site appears in the Computer folder. You can drag that shortcut to your desktop so that it's easy to find later.

DROP multiple TABLE / TRIGGER / FUNCTON in oracle using PL SQL

To drop more than one tables having a matching criteria then we should use a PL SQL statement, in oracle there is a table called USER_OBJECTS having name of all the tables for that particular user.

DROP TABLE is a DDL statement so that we need EXECUTE IMMEDIATE privilege for dropping table from a script, more easy way to drop table is to generate DROP TABLE command using a script and run that command.

The following PL SQL script generate drop table command for all tables having table name contains word 'test'

SET SERVEROUTPUT ON;

DECLARE
object_name varchar2(100);
cursor cur1 is SELECT object_name FROM user_objects WHERE object_type='TABLE' AND object_name LIKE '%test%';
BEGIN

open cur1;
loop
       fetch cur1 into object_name;
       exit when cur1%notfound;
      dbms_output.put_line('DROP TABLE ' || object_name || ';' );
   end loop;
   close cur1;

END ;

Output

anonymous block completed

DROP TABLE USER_TEST;

S	M	T	W	T	F	S
