Subject [jira] [Updated] (PHOENIX-952) Support ANY and ALL built-ins for ARRAYs
Date Wed, 11 Jun 2014 12:43:02 GMT

     [ https://issues.apache.org/jira/browse/PHOENIX-952?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

ramkrishna.s.vasudevan updated PHOENIX-952:
-------------------------------------------

    Attachment: Phoenix-952_5.patch

Updated patch.  Actually thought not to use ARRAY_ELM_REF in this but add a new node and a
new expression.  Then decided not to do that(as per your suggestion). If needed can even add
a new node and an expression for that and use instead of ARRAY_ELEM_REF.
The ArrayAny(All)Expression creates a loop and inside it forms a new ComparisonExpression
so that the evaluate() would be able to fetch every element in the Array and then do the comparison
on that. 
ArrayAllExpression is a subclass of ArrayAnyExpression and what to return as a result after
comparison (true or false) is actually overridden.

> There's currently no good way to search array elements. We should support the ANY and
ALL built-ins for our ARRAY type like Postgres does: http://www.postgresql.org/docs/9.1/static/arrays.html#ARRAYS-SEARCHING
