USE mysql;

where mysql is the db name

To display all tables in the chosen database


To display all columns in a table:


where user is the table name

Or a single step command:

SHOW COLUMNS FROM `user` FROM `databasename`;[/code]
To display data in a coloumn or field:
SELECT `gamma` FROM `user`;

Where user is the table name and gamma is the field or coloumn name
