Chapter 3: Tutorial Introduction 151 you. (If you make a poor choice and it turns out later that you need a longer eld, MySQL provides an ALTER TABLE statement.) Animal sex can be represented in a variety of ways, for example, "m" and "f", or perhaps "male" and "female". It's simplest to use the single characters "m" and "f". The use of the DATE data type for the birth and death columns is a fairly obvious choice. Now that you have created a table, SHOW TABLES should produce some output: mysql> SHOW TABLES; +---------------------+ | Tables in menagerie | +---------------------+ | pet | +---------------------+ To verify that your table was created the way you expected, use a DESCRIBE statement: mysql> DESCRIBE pet; +---------+-------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +---------+-------------+------+-----+---------+-------+ | name | varchar(20) | YES | | NULL | | | owner | varchar(20) | YES | | NULL | | | species | varchar(20) | YES | | NULL | | | sex | char(1) | YES | | NULL | | | birth | date | YES | | NULL | | | death | date | YES | | NULL | | +---------+-------------+------+-----+---------+-------+ You can use DESCRIBE any time, for example, if you forget the names of the columns in your table or what types they are. 3.3.3 Loading Data into a Table After creating your table, you need to populate it. The LOAD DATA and INSERT statements are useful for this. Suppose your pet records can be described as shown here. (Observe that MySQL expects dates in YYYY-MM-DD format; this may be dierent from what you are used to.) name owner species sex birth death Fluy Harold cat f 1993-02-04 Claws Gwen cat m 1994-03-17 Buy Harold dog f 1989-05-13 Fang Benny dog m 1990-08-27 Bowser Diane dog m 1998-08-31 1995-07-29 Chirpy Gwen bird f 1998-09-11 Whistler Gwen bird 1997-12-09 Slim Benny snake m 1996-04-29 Because you are beginning with an empty table, an easy way to populate it is to create a text le containing a row for each of your animals, then load the contents of the le into the table with a single statement.
