Rick Hillegas updated DERBY-4583:
---------------------------------
Attachment: derby-4583-01-ac-booleanLiterals.diff
Attaching derby-4583-01-ac-booleanLiterals.diff. This patch re-enables the
boolean literals TRUE and FALSE. The regression tests passed for me after
applying this patch.
Touches the following files:
---------
M java/engine/org/apache/derby/impl/sql/compile/sqlgrammar.jj
Small edit to enable the literals.
---------
M
java/testing/org/apache/derbyTesting/functionTests/tests/lang/BooleanValuesTest.java
New test case to verify that the literals work again.
---------
M
java/testing/org/apache/derbyTesting/functionTests/tests/lang/db2Compatibility.sql
M
java/testing/org/apache/derbyTesting/functionTests/master/db2Compatibility.out
M
java/testing/org/apache/derbyTesting/functionTests/master/implicitConversions.out
Tweaks to other regression tests to reflect the new behavior.

> 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?
