in case anyone else wants to auto test for such an issue, a have made a 
minimal config for a testcase:

You need a working database, but you don't need a sql setup in that db except a valid login.
You DO NOT need a running exim to have that testcase working.

exim.conf:

#
# minimum test config for db access
#

primary_hostname = testfarm.yourproject.edu

keep_environment = PATH

message_logs                        = false

hide mysql_servers = localhost/<DBNANE>/<DBUSER>/<DBPASSWORD>

/exim.conf

a working example:

# exim -be '${lookup mysql {SELECT 1}}'
1

a none working example:

# exim -be '${lookup mysql {SELECT * from mail_config LIMIT 1}}'
Failed: unknown lookup type "mysql"
