-------------------------------------------

Derby does not support the BOOLEAN data type. See DERBY-499.

> A SELECT query with a literal boolean value in its WHERE clause results in a syntax error.
> How to reproduce:
> CREATE TABLE list (value VARCHAR(10));
> Given this table, the following queries result in a syntax error.
> SELECT * FROM list WHERE TRUE;
> SELECT * FROM list WHERE FALSE;
> SELECT * FROM list WHERE value='A' OR TRUE;
> Why is TRUE/FALSE not a boolean expression?
