> 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.
