Having problem with many to many join. Below is the schema with tables
and sql statements. All seems to work with the following exception: Can
not get all the field names to display.


// 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';


// 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

left join member on (member.member_dist_no = member_cccp_lnk.member_dist_no)
where member_cccp_lnk.cccb_id = '0200';

Whats the problem,

I uploaded your db to mysql 5.0.27+GUI-TOOLS 1.2.5 BETA on WindowsXP and all
*4* queries ran sucessfuly with no errors, and return good data.

// 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'

I have since created a join that works but I thought the joins I
submitted should have worked. I was looking for some thoughts as to why
they did not.
