The best I think you could achieve would be something like this...
Global ExecuterService es;
rule "execute some SQL"
when
$q : Query()
$f : Fields(query == $q)
$t : Tables(query == $q)
$p : Predicates(query == $q)
then
es.execute($f, $t, $p);
end
Still not sure if a rules engine is your best option, if I understand
your use case correctly.

Let me see if I understand correctly.
You want the user to be able to define the SQL query (table,
field list, predicates) and have the resulting SQL executed within
Drools?
Is this your only requirement for the rules engine; if so have
you thought a rules engine might not be your best option.

Subject: [rules-users] How to execute the SQL query
using drools
Hi Anstis,
I'm creating a rule engine which is basically a SQL
query executor. for that i need to have a drool
file where i can add new rules to build the different
query criteria. user should be able to create new selection criteria.
is there any way that i can define sql queries in side
the drool files.
thanks
