[Exim] MySQL Group expansion trouble

I am running exim 3.36 and I have the following director setup in my
configure file...

mysql_group_aliases:
driver = aliasfile
file_transport = address_file
pipe_transport = address_pipe
search_type = mysql
query = "SELECT username FROM users, divisions WHERE users.division =
divisions.divId AND LCASE(divisions.emailName) = LCASE('$local_part')"

My divisions table simply maps a common email group
name(divisions.emailName) to a division id(divisions.divId). So, my
query checks to see if $local_part matches one of the division common
email group names and if it does attempts to expand a list of users that
have that id in their users.division field.

When I execute this query by hand it produces a proper list of the users
in the particular division. However, when Exim processes the query it
says, "MYSQL: query failed: Unknown column 'divisions.emailName' in
'where clause'".

Here is a snippet of the debug level 10 code I have collected.

---------------------------------------

df_lookup entered: search type = mysql

divisions WHERE users.division = divisions.divId AND

Any ideas?
