php - Permutating Result Set of My Query, Something is wrong -


i have 4 tables:

  1. persons
  2. jobs
  3. titles
  4. departments

persons table

id | title_id | person | phone | email | dept_id | job_id ---+----------+--------+-------+-------+---------+------- 1  |        1 | some1  | 12345 | s@a.c |       2 |      3 ...

other tables' structures same following

id | ********  ---+---------

assume there 5 records in table titles, 5 records in table departments , 5 job records in table jobs.

and let's suitable records defined $search string = 6 in table persons;

when execute query below, result set has 5 x 5 x 5 x 6 = 750 records , of them repetitive. results doing permutation.

$query = sprintf(                   "select *                                               persons p, titles t, departments d, jobs j                                               p.person %s or                           p.phone %s or                           p.email %s ,                           p.id=t.id ,                           p.id=j.id ,                           p.id=d.id",                     $search, $search, $search                   );

then have tried changed conditions following:

$query = sprintf(                   "select *                                               persons p, titles t, departments d, jobs j                                               p.person %s or                           p.phone %s or                           p.email %s ,                           p.title_id=t.id ,                           p.job_id=j.id ,                           p.dept_id=d.id",                     $search, $search, $search                   );

this returns same result. want title's instead of title_id, job's instead of job_id , department's name instead of dept_id in result set, @ once.

what doing wrong?

try using join:

$query = sprintf(                   "select *                                               persons p join titles t on p.title_id=t.id join departments d on  p.dept_id=d.id join jobs j on p.job_id=j.id                                              p.person %s or                           p.phone %s or                           p.email %s                    ",                     $search, $search, $search                   );

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 ...
