Rick Hillegas resolved DERBY-4583.
----------------------------------

    Issue & fix info:   (was: [Patch Available])
          Resolution: Fixed

Committed derby-4583-01-ad-booleanLiterals.diff at subversion revision 952348. The tests ran cleanly for me except for the following error in NetworkServerMBeanTest. The test passed when I re-ran it standalone. I believe that the error is a timing-related heisenbug in that test and is not related to the changes in this patch.

There was 1 error:

> 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?
