[Steven Hawkins (JIRA)]

     [ https://issues.jboss.org/browse/TEIID-2159?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Steven Hawkins updated TEIID-2159:
----------------------------------

    Fix Version/s: 8.3
          Affects: Documentation (Ref Guide, User Guide, etc.),Release Notes


pg distills this a little more - http://www.postgresql.org/docs/devel/static/functions-json.html

It seems best to add a json type so that we are validating.

JsonParse/JsonSerialize (if we want to support other encodings / pretty print options)
JsonObject (basically the same as pg row_to_json)
JsonArray 
JsonAgg (necessary since we lack formal array support)

> SQLXML is standard that lets users define XML constructs to define a XML documents using SQL. However there is such standard exists for producing the JSON based documents. 
> It would be nice if Teiid provides such SQL language extensions produce and deal with JSON documents. The constructs equivalent from SQLXML are
> JsonParse
> JsonObject
> JsonArray
> JsonForrest
> JsonAgg
