Having problem with many to many join or select understanding.

Looking for help with the design or sql to get the member.member.lname
with query 1 and cccb.com_name on query 2.

Any help will be appreciated. TIA

// sql selecting cccb(s) that member is on
// problem is can not get 'member name' to display
// if put 'member.member_lname' in select statement get error msg
// Unknown column 'member.member_lname' in 'field list'

select member_cccp_lnk.member_dist_no, member_cccp_lnk.cccb_id,
cccb.com_name
from member_cccp_lnk
left join cccb on (cccb.cccb_id = member_cccp_lnk.cccb_id)
where member_cccp_lnk.member_dist_no = '0008';


// sql selecting member(s) on cccb
// problem is can not get 'cccb name' to display
// if put 'cccb.com_name' in select statement get error msg
// Unknown column 'cccb.com_name' in 'field list'

select member.member_fname, member.member_lname
