select a.id,a.name,a.photo,b.category_name,b.category_id
from table-A a join table-B s ON a.category_id = b.category_id
where parent_id = 1

Answer 2

請嘗試以下；

Select TBLA.ID, TBLA.Name, TBLA.Photo, TBLB.Category_Name, TBLB.Category_ID
From [table-B] TBLB
Inner Join [table-a] TBLA On TBLA.Category_ID = TBLB.Category_ID
Where TBLB.Parent_ID = 1 
And TBLA.ID = (Select Max(ID) 
      From [table-a]
      Where Category_ID = TBLB.Category_ID)
