Answer 1

MySQL requires numeric constants for that LIMIT syntax.

From http://dev.mysql.com/doc/refman/5.7/en/select.html:

The LIMIT clause can be used to constrain the number of rows returned by the SELECT statement. LIMIT takes one or two numeric arguments, which must both be nonnegative integer constants, with these exceptions:

• Within prepared statements, LIMIT parameters can be specified using ? placeholder markers.

• Within stored programs, LIMIT parameters can be specified using integer-valued routine parameters or local variables.

Compute the constant on the Java side.
