Selecting data from two MySQL tables at once in php -


what have tried achieve;

counting number of rows in 2 tables (adding them together) grouping them country code in country column in table. output results number of rows , country e.g.

  • gb => 200 views
  • us => 500 views
  • ch => 119 views

mysql code have far;

select count(id) totalclicks, country adverts_analytics_user_clicks advertid =:advertid group country

this works well, need select same data table @ same time , combine count() values according country field.

any appreciated!

repeat first query against second table, such output coumns have same name , datatype.

then union results together.

finally sum total clicks country.

select country, sum(totalclicks) totalclicks  ( select count(id) totalclicks, country adverts_analytics_user_clicks advertid =:advertid group country union select count(id) totalclicks, country table 2 advertid =:advertid group country ) group country
