database - oracle grammar to h2 grammar (+) join table -


i have following query oracle

   select distinct count(pa.payment_id)       location c,    inventory e,     inventory_stock es,    payment_client ep,     payment pa,    currency cur,     location s,    exchange_country exc,     exchange_rate sso,     exchange_hike so,     exchange_margin sov      cur.outstate = 'n' ,     c.location_id = e.location_id ,     e.inventory_id = ep.inventory_id ,     e.inventory_stock_id = es.inventory_stock_id ,     ep.client_id = pa.end_client ,     pa.cur_id = cur.cur_id ,     cur.location_id = s.location_id ,     c.client_id  not null  ,     cur.cur_id = exc.cur_id(+) ,     exc.exchange_id = sso.exchange_id(+) ,     sso.account_id = so.account_id(+) ,     so.option_name(+)  = 'premium' ,     exc.exchange_id = sov.exchange_id(+) ,     sov.name(+)  = 'value';

right using h2 database , syntax error got so.option_name(+) , sov.name(+); know (+) oracle's way of right join , left join there possible way convert h2 error , grammar equivalent?

it's time move on. oracle's legacy outer join syntax no longer recommended oracle. from docs:

oracle recommends use clause outer join syntax rather oracle join operator. outer join queries use oracle join operator (+) subject following rules , restrictions, not apply clause outer join syntax [...]

if replace (+) usage outer join, not query work on both oracle , h2, important step forward application whole.

select distinct count(pa.payment_id)  location c join inventory e on c.location_id = e.location_id join payment_client ep on e.inventory_id = ep.inventory_id join inventory_stock es on e.inventory_stock_id = es.inventory_stock_id join payment pa on ep.client_id = pa.end_client join currency cur on pa.cur_id = cur.cur_id join location s on cur.location_id = s.location_id left join exchange_country exc on cur.cur_id = exc.cur_id left join exchange_rate sso on exc.exchange_id = sso.exchange_id left join exchange_hike    on sso.account_id = so.account_id   , so.option_name = 'premium' left join exchange_margin sov    on exc.exchange_id = sov.exchange_id   , sov.name = 'value' c.client_id not null , cur.outstate = 'n'

the importance when converting (+) left join pay close attention predicates must go on clause, , predicates fine in where clause. in particular, following 2 predicates must go in relevant left joined table's on clause:

  • so.option_name(+) = 'premium'
  • sov.name(+) = 'value'

resizing Telegram inline keyboard -

telegram's inline keyboard great feature lots of different use cases. inline buttons added list of items this: inline_keyboard = [[inlinekeyboardbutton(text="button", callback_data="button"), inlinekeyboardbutton(text="reset",callback_data="reset")]] inline_keyboard_markup = inlinekeyboardmarkup(inline_keyboard) update.message.reply_text("hi", reply_markup=inline_keyboard_markup) the above code adds 2 buttons each half width of chat screen. i know the normal keyboard button there resize_keyboard parameter somehow can used. my question is there way resize inline buttons ? example make full width or quarter width. unfortunately, can't now. :( you can suggest @botsupport , might add feature next version.

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...
