Java long to MySql
Solution 1:
SIGNED BIGINT is a 8-bytes long integer just like Java's long.
Solution 2:
Java long max value is positive: 9,223,372,036,854,775,807
This means for positive only unsigned numbers UNSIGNED BIGINT(19) should be enough or you can just use UNSIGNED BIGINT which is equal to UNSIGNED BIGINT(20)
If you are going to use negative numbers as well BIGINT(19) will be enough.
