sql server - sql - multiple layers of correlated subqueries -


i have table a, b , c

i want return entries in table not exist in table b , of list not exist in table c.

select * table_a not exists (select 1 table_b b a.id = b.id)

this gives me first result of entries in not in b. want entries of result not in c.

i tried flavours of:

select * table_a not exists (select 1 table_b b a.id = b.id) , not exists (select 1 table_c c a.id = c.id)

but isnt correct logic. if there way store results first query , select * result not existent in table c. i'm not sure how that. appreciate help.

you have 2 where clauses in (the external part of) second query. not valid sql. if remove it, should work expected:

select * table_a not exists (select 1 table_b b                   a.id = b.id) ,       not exists (select 1 table_c c            -- removed                   a.id = c.id) ;

tested in sql-fiddle (thnx @alexander)

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
