Dumindu Buddhika updated PHOENIX-2064:
--------------------------------------
    Attachment: PHOENIX-2064-v2.patch

[~jamestaylor] I added the changes you suggested in this patch.  But without 
changing position variable at the end some test cases at ArrayIT fails. 
eg:
testSelectWithArrayWithColumnRefWithVarLengthArrayWithNullValue

it fails here 
{code}
assertTrue("Expected to start with " + expectedPrefix,
                rs.getString(2).startsWith(expectedPrefix));
{code}

> ARRAY constructor doesn't work when used in COUNT DISTINCT

> As a workaround for PHOENIX-2062, I tried the following query:
> {code}
> SELECT COUNT(DISTINCT ARRAY[a.col1, b.col2]) ...
> {code}
> However, this always returns the full number of rows which is wrong.
