What is the operator "=>" we can often see in the UTL_TCP usage examples ?
As in http://www.oracle-base.com/articles/misc/ftp-from-plsql.php
l_conn := ftp.login('ftp.company.com', '21', 'ftpuser', 'ftppassword');
ftp.ascii(p_conn => l_conn);
ftp.get(p_conn => l_conn,
p_from_file => '/u01/app/oracle/test.txt',
p_to_dir => 'MY_DOCS',
p_to_file => 'test_get.txt');
ftp.logout(l_conn);
I dont understand what is the purpore of "p_conn => l_conn", since we never use p_conn anywhere. Even closing the connection is done with ftp.logout(l_conn), not using p_conn. All the variables used before this operator "=>" arent even defined anywhere.
Maybe it's an operator specific to the UTL_TCP package, because I never saw it being used anywhere else, and cant find it in any PL/SQL documentation, Oracle or otherwise.
