Hyunsik Choi updated TAJO-272:
------------------------------
Attachment: TAJO-272.patch
This patch fixes the bug and adds various unit test for boolean test as follows:
{code:java}
testSimpleEval("select 1 < 3 is true", new String [] {"t"});
testSimpleEval("select 1 < 3 is not true", new String [] {"f"});
testSimpleEval("select 1 < 3 is false", new String [] {"f"});
testSimpleEval("select 1 < 3 is not false", new String [] {"t"});
testSimpleEval("select not (1 < 3 is true)", new String [] {"f"});
testSimpleEval("select not (1 < 3 is not true)", new String [] {"t"});
testSimpleEval("select not (1 < 3 is false)", new String [] {"t"});
testSimpleEval("select not (1 < 3 is not false)", new String [] {"f"});
testSimpleEval("select 1 > 3 is true", new String [] {"f"});
testSimpleEval("select 1 > 3 is not true", new String [] {"t"});
testSimpleEval("select 1 > 3 is false", new String [] {"t"});
testSimpleEval("select 1 > 3 is not false", new String [] {"f"});
testSimpleEval("select not (1 > 3 is true)", new String [] {"t"});
testSimpleEval("select not (1 > 3 is not true)", new String [] {"f"});
testSimpleEval("select not (1 > 3 is false)", new String [] {"f"});
testSimpleEval("select not (1 > 3 is not false)", new String [] {"t"});
{code}
