mysql - Get everything from table, but if network_id is 9, only take 2 of them -


1st

select b.*, network_9.*, c.id click  `banners` b, (     select id      `banners` b      left join `clicks` c     on b.id = c.banner_id , c.user_id = 1              b.`network_id` = 9 ,         b.`status` = 1 ,         b.`type` in(1, 2) ,         c.`id` null      limit 2 ) network_9  left join `clicks` c on b.id = c.banner_id , c.user_id = 1      b.`network_id` not in(network_0) ,     b.`status` = 1 ,     b.`type` in(1, 2) ,     c.`id` null  limit 0, 10

2nd

select     b.*,     c.id click      `banners` b  left join `clicks` c on b.id = c.banner_id , c.user_id = 1      b.`status` = 1 ,     b.`type` in(1, 2) ,     c.id null  limit 0, 10

i'm trying rows banners, if network_id 9, take 2 of them, , still others.

the 1st attempt somethin tried, failed.

and 2nd basic sql, takes rows, doesn't check on network_id

my first , realy simple aproche is:

  1. select rows banner network_id not equal 9 select
  2. select rows banner network_id equal 9 , limit them 2

second aproche be: first try: subselect ids of rows banner network_id equal 9 , limit them 2. main select rows allow rows dont having network_id equal 9 or inside subselect

select * banner id in (select id banner network_id = 9 limit 2) or network_id != 9
