Getting column values as array, Zend_Db, Mysql, php -


i have following database tables:

  1. table: person columns: id, first_name, age, city, state
  2. table: study columns: id, name, description, notes
  3. table: person_studies columns: person_id, study_id, notes

i need study names particular person involved in:

person.id, person.first_name, person.city, study.name 

this query wrote data person.id = 14:

select person.id, person.first_name, study.name person left join person_studies on person.id = person_studies.person_id left join study on person_studies.study_id = study.id  person.id=14; 

since there multiple studies person involved in, getting more 1 row in result set. need implement using zend_db api's.

the questions are:

    1. there better way write query?
    2. if want study.name values in separate array part of result set, possible in query such when run query in zend:
         `$result = $this->fetchall($select);`  
    $select sql statement $result should of following format:
         [0] => array     (       [person.id] => 14       [first_name] =>jamie       [study_names] => array                         (                           [0] => biotechnology;                           [1] => mathematics;                           [2] => aeronautics;                        )      ) 

any appreciated.

thanks

i not find better way write query, far second question goes, found following solution of using group_concat().

the final query looks now:

select person.id, person.first_name, person.city, person.state, group_concat(study.name separator '|') studynames person left join person_studies on person.id = person_studies.person_id left join study on person_studies.study_id = study.id  person.id=14; 

we can specify other clauses within group_concat eg distinct . please refer link http://dev.mysql.com/doc/refman/5.0/en/group-by-functions.html#function_group-concat detailed description clause.
