== Basic Data Manipulation Examples On Hbase Shell ==

=== Create a table in an HBase ===

{{{
HBase > CREATE Movie (
    --> year, length, inColor, studioName, vote, producer)
    --> NUM_VERSIONS 10; 

HBase > CREATE MovieStar (
    --> biography, filmography, gender, birthDate)
    --> NUM_VERSIONS 10;
}}}

=== Insert data into a table ===
{{{
HBase > INSERT INTO Movie (year:, length:, inColor:, studioName:, vote:user_1, producer:)
    --> VALUES ('1977', '124', 'true', 'Fox', '5', 'George Lucas')
    --> WHERE row='Star Wars';


HBase > INSERT INTO MovieStar (biography:, 'filmography:Star Wars', gender:, birthDate:)
    --> VALUES ('blah blah', 'starring', 'male', 'March 31, 1971')
    --> WHERE row='Ewan Gordon Mc.Gregor'; 
}}}

=== Show all data in a table ===
{{{
HBase > SELECT * Movie;
}}}

INSERT INTO Movie (genre:) VALUES ('action, adventure, fantasy') WHERE row = 'Star Wars';
