Question

i have a db like below:
(sorry i couldn’t upload the diagram)

group table:

grp_id smallint 
grp_name char(50) 

type table:

tp_id smallint 
tp_name char(50) 

item table:

it_id int 
grp_id smallint  
tp_id smallint 

item table is linked to group table by grp_id, and is linked to type table via tp_id.

the user enter the grp_name or grp_id,
and i should realize which item have this group and add the type names of them, from type table to a checklistbox.

Answer 1

select it_id, tp_name
from item
inner join type on type.tp_id = item.tp_id
inner join [group] on [group].grp_id = item.grp_id
where [group].grp_id = @groupid or [group].grp_name = @groupname
