When running this query it does indeed fail
SELECT DISTINCT r.name,c.dcheckid,c.type,c.key_,c.ports. FROM drules r,dchecks c WHERE r.druleid=c.druleid AND r.druleid BETWEEN 000000000000000 AND 099999999999999
However
mysql> SELECT DISTINCT r.name,c.dcheckid,c.type,c.key_,c.ports FROM drules r,dchecks c WHERE r.druleid=c.druleid AND r.druleid BETWEEN 000000000000000 AND 099999999999999;
Works fine.
NOTE the . removed after the c_ports.
I am unable to add new conditions as discoverychecks.
