oracle - Getting multiple column values in single row -


this actual result , have used store details of client

    sid       attribute_values   attribute_id           ---------- ----------------   -----------     20         101010             membership_no      20         allen              membership_name     20         ward               membership_lname     30         101011             membership_no     30         martin             membership_name     30         blake              membership_lname

in need retrieve details based on membership no , using sid. sid unique number . need show result 

    sid membership_no membership_name membership_lname     -----   ------------- --------------- ----------------     20      101010        allen           ward     30      101011        martin          blake

above 3 attributes constant using values client number, names inserts table. im stuck this...i need solution it.

this query have used retrieve details. returns empty

    select sid,  listagg(attribute_value, ',') within group      (order attribute_value) att customer_attributes      sid ='20' , attribute_value='101010'     , attribute_id ='membership_no'     , attribute_id ='membership_name'     , attribute_id ='membership_lname'     group sid;

you can join. listagg wont create 3 columns:

select      a.sid,     a.attribute_values membership_no,     b.attribute_values membership_name,     c.attribute_values membership_lname tbl  join tbl b on a.sid = b.sid join tbl c on c.sid = b.sid a.attribute_id = 'membership_no' , b.attribute_id = 'membership_name' , c.attribute_id = 'membership_lname'

demo sqlfiddle

this gives same result;

select      sid,     max(decode(attribute_id, 'membership_no', attribute_values, '')) membership_no,     max(decode(attribute_id, 'membership_name', attribute_values, '')) membership_name,     max(decode(attribute_id, 'membership_lname', attribute_values, '')) membership_lname tbl  group sid order sid

same can done pivot also

select * tbl pivot(     max(attribute_values) attribute_id in (         'membership_no' membership_no,          'membership_name' membership_name,          'membership_lname' membership_lname     ) ) order sid

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...
