Hi I''m using integer for most of my numeric data, and this is fine, but the system I am building will convert my data structures OLTP to OLAP for reporting. This will require TONS of data to be saved. In an effort to reduce wasted space I''d rather use tinyint/smallint and other such more precise data types in mysql. Couldn''t find any documentation about these ''nonstandard'' data types. In addition I couldn''t find anything on use column options like "unsigned". Thanks. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
