postgresql - removing leading zero and hyphen in Postgres -


i need remove leading zeros , hyphens column value in postgresql database, example:

121-323-025-000 should 12132325 060579-0001 => 605791 482-322-004 => 4823224

timely appreciated.

postgresql string functions. more advanced string editing, regular expressions can powerful. aware complex regular expressions may not considered maintainable people not familiar them.

create table testdata (id text, expected text); insert testdata (id, expected) values     ('121-323-025-000', '12132325'),     ('060579-0001', '605791'),     ('482-322-004', '4823224'); select id, expected, regexp_replace(id, '(^|-)0*', '', 'g') computed   testdata;

how regexp_replace works. in case beginning of string or hyphen place start matching. include zeros follow part of match. next replace match empty string. finally, global flag tells repeat search until reach end of string.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
