[exim] Converting to Mysql?

Hi there. I have at the moment:

LOCAL_DOMAINS = SELECT DISTINCT host FROM  localhosts WHERE host = 
'${quote_mysql:$domain}'
domainlist local_domains         = mysql;LOCAL_DOMAINS

And these work fine.. but how do I convert these queries to mysql versions?
so I can put the data into a database like the domains?

hostlist rbl_whitelist           = net-iplsearch;/etc/exim4/rbl_whitelist
hostlist high_ratelimit          = partial-lsearch;/etc/exim4/high_ratelimit

Thanks
Craig
