You may see the entry about CSV in Wikipedia.

You may find useful links in there.

You can also consult the source code of MySQL, 
especially the part where the select, or load syntaxes 
are implemented.

> 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.
