The following page has been changed by GavinHeavyside: http://wiki.apache.org/hadoop/Hive/LanguageManual/DDL ------------------------------------------------------------------------------ This statement lets you change the name of a table to a different name. '''The location of the data and the names of partitions do not change!''' In other words, the old table name is not "freed," and writing to it will alter the "renamed" table's data! - === Add/Repalce Columns === + === Add/Replace Columns === {{{ ALTER TABLE table_name ADD|REPLACE COLUMNS (col_name data_type [COMMENT col_comment], ...) }}}
