According to this documentation, BIGINT is just a 64-bit integer in MySQL - so use setLong. That should be fine for signed BIGINT types in MySQL. Unfortunately Java doesn't have an "unsigned long" type, so if you have an unsigned BIGINT in your database that could be trickier - you could try still using setLong, and see whether it just overflows in the "natural" way.
