/**
* Base BETWEEN clause function for SQL queries.
*
* The purpose of this clause function is to find that a given
* value can be found in a given A...B interval.
*
*
* The first token in the $X{...} syntax is the function ID token. Possible values for
* the BETWEEN clause function ID token are:
*
* BETWEEN
- in this case the A...B interval will be considered open: (A,B)
* [BETWEEN
- in this case the A...B interval will be considered right-open: [A,B)
* BETWEEN]
- in this case the A...B interval will be considered left-open: (A,B]
* [BETWEEN]
- in this case the A...B interval will be considered closed: [A,B]
