The second and third arguments of the SUBSTRING function denote the starting position and length of the substring to be returned. These arguments are integers. The first position of a string is denoted by 1. The SUBSTRING function returns a string.
JPA 1.0:
BNF ::= SUBSTRING(string_primary, simple_arithmetic_expression, simple_arithmetic_expression)
JPA 2.0:
BNF ::= SUBSTRING(string_primary, simple_arithmetic_expression [, simple_arithmetic_expression])
