Need query help on translation table problem

Databases
1

Hi guys,

I basically have two tables: locales_source (which includes English source phrases) and locales_target (which includes all the translated phrases).

I’m looking for a way to list the English phrases (from locales_source) only if translations in de, fr, and es exist in locales_target.

Any help would be appreciated.

Here’s some table info:

mysql> describe locales_source;

select <columnsOfInterest>
  from locales_source
  join (select lid
          from locales_target
         where language in ('de','fr','es')
         group
            by lid
        having count(*) = 3) dt
    on locales_source.lid = dt.lid
3

Thanks swampBoogie.

It works when I specify “source” as the <columnsOfInterest> but when I add lid to the column list, I run into a problem:

    ->   from locales_source

    ->           from locales_target

    ->          group
    ->             by lid
    ->         having count(*) = 3) dt
    ->     on locales_source.lid = dt.lid
    ->     limit 10;

Column ‘lid’ in field list is ambiguous means that you have to qualify it just like you did in the ON clause

Works like a charm!

mysql> select ls.lid, ls.source
    ->   from locales_source ls
    ->   join (select lid
    ->           from locales_target
    ->          where language in ('de','fr','es')
    ->          group
    ->             by lid
    ->         having count(*) = 3) dt
    ->     on ls.lid = dt.lid
    ->     limit 10;
