I have two fields: one to store an excerpt with a max size of 500 characters, and another to store a description with a max size of 10,000 characters. What data types should I use, TEXT or VARCHAR...

What's the most appropriate (read least data consuming) data field to store a true/false/1/0 value in a mySQL database? I have previously used a one character long tinyint, but I am not sure if it...
