Your script should look like this
UPDATE `cq_eudemon_rbn_rqr` SET `min`='your value';
UPDATE `cq_eudemon_rbn_rqr` SET `max`='your value';
If you want to define it to a certain required star universal to compose with
UPDATE `cq_eudemon_rbn_rqr` SET `min`='your value' Where `sacrifice_starlev` = 'star value';
UPDATE `cq_eudemon_rbn_rqr` SET `max`='your value' Where `sacrifice_starlev` = 'star value';
and so on
(note the standard sacrifice star values are, 0, 50, 75, 100, 200, 280, 480, 600, 800, 1200, 1500, 1800, 2000, 2500, 3000. Also note 100 here = 1* in game)
Hope this helps
Look at the spoiler
You would use the second options and put the lower sacrifice_starlev at high min and max numbers and the 3000 sacrifice_starlev at whichever you wanted the max star to compose at
