Codeigniter는 두 개의 결과를 결합합니다.

Question

두 개의 쿼리가 있습니다. 두 쿼리를 실행하고 동일한 결과 개체에서 반환해야합니다. 예를 들어

$query1 = "SELECT name,age from students"; 
$query2 = "SELECT name,age from users"; 
$result1 = $this->db->query($query1) 
$result2 = $this->db->query($query2) 
return result1 and result 2 together ; 

동일한 개체에서 두 쿼리의 결과를 모두 반환해야합니다. 나에게

도와주세요 실제 쿼리는 : 당신은 테이블 행이 속하는 레코드를 식별하려면

가

SELECT dev_members.name,dev_members.id,dev_members.age,dev_members.family_id,dev_family.house_name,dev_ib_account_registration.account_id FROM (dev_members) 
JOIN dev_family ON dev_family.id=dev_members.family_id 
JOIN dev_ib_account_registration ON dev_ib_account_registration.member_id=dev_members.id 
      UNION 
SELECT dev_members.name,dev_members.id,dev_members.age,dev_members.family_id, dev_family.house_name,dev_ib_sub_member_registration.account_id FROM (dev_members) 
JOIN dev_family ON dev_family.id=dev_members.family_id 
JOIN dev_ib_sub_member_registration ON dev_ib_sub_member_registration.member_id=dev_members.id 

Answer 1

당신은 UNION

$query = "SELECT name,age from students 
      UNION 
      SELECT name,age from users"; 
$result = $this->db->query($query); 

또는를 사용하여 다음

$query = "SELECT name,age, 'students ' AS `table_type` from students 
      UNION 
      SELECT name,age, 'users' AS `table_type` from users"; 
$result = $this->db->query($query); 

에

Answer 2

$query = "SELECT name,age from students UNION ALL SELECT name,age from users"; 

당신은 당신의 쿼리

SELECT dev_members.name,dev_members.id,dev_members.age,dev_members.family_id,dev_family.house_name,dev_ib_account_registration.account_id FROM (dev_members) 
JOIN dev_family ON dev_family.id=dev_members.family_id 
JOIN dev_ib_account_registration ON dev_ib_account_registration.member_id=dev_members.id 
      UNION ALL 
SELECT dev_members.name,dev_members.id,dev_members.age,dev_members.family_id, dev_family.house_name,dev_ib_sub_member_registration.account_id FROM (dev_members) 
JOIN dev_family ON dev_family.id=dev_members.family_id 
JOIN dev_ib_sub_member_registration ON dev_ib_sub_member_registration.member_id=dev_members.id 

UNION은 UNION ALL은 중복을 유지하면서 설정 최종 결과에서 행을 반복 제거에 UNION ALL 대신 UNION을 사용할 필요가있다.
