Subject [jira] Updated: (HADOOP-1720) [HbaseShell] Addition of HQL (Hbase Query Language) support in Hbase Shell
Date Wed, 05 Sep 2007 17:31:34 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-1720?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

stack updated HADOOP-1720:
--------------------------

    Status: In Progress  (was: Patch Available)

Moving issue status back to 'resume progress' (Otherwise, it would seem to trigger a hudson
build on each new patch upload).

Edward: Help me out.  I'm having difficulty distinguishing where  'string literals' and 'identifiers'
should be used.  Your example above confuses me.  Row name is a 'string literal' but i'd think
that a users would be inclined to group row name with column and table names and therefore
classify row name an 'identifier' and therefore worthy of double-quotes.

Inchul: I took a look at other sql create syntax and indeed column specification are wrapped
in parens.

> We have defined the HQL (Hbase Query Language), which is a "more" SQL-like query language
for Hbase, for use in Hbase Shell. HQL is not intended to fully support the SQL syntax and
semantics. HQL, instead, is developed to make it easy to manipulate tables in Hbase through
the Hbase Shell command line, without using programming APIs.
> You can find more information about HQL in http://wiki.apache.org/lucene-hadoop/Hbase/HbaseShell/HQL.
