一列SQL中的Concat ID

Question

I am using multiple join query in Mysql,

Table A
IdA  
name 

Table B 
idB
name
A_id

Is there a possible way to build request that returns idA name VIRTUAL_FIELD

VIRTUAL_FIELD contains all the IDs of table B referenced to table A ?

For example

Table A
IdA  : 1
name  : Bananas

Table B 
idB : 1
name : I
A_id : 1

idB : 2
name : K
A_id : 1

idB : 3
name : D
A_id : 1

My request returns

IdA  : 1
name  : Bananas
VIRTUAL_FIELD : 1,2,3  or [1,2,3] etc..

Any help would be appreciated

Answer 1

SELECT A.IdA, A.name, GROUP_CONCAT(B.idB) as VIRTUAL_FIELD 
  from TABLE A INNER JOIN TABLE B 
   ON B.A_id=A.IdA GROUP BY A.IdA

use group concat and group by
