to see what tables you have, just type in to the mysql prompt
show tables;
this will provide you with a list of your tables.
to see a description of a table, type
describe tablename ;
so say you have this scenario:
create table customer (id_num mediumint unsigned auto_increment not null,
[INDENT]customer_name varchar(30),[/INDENT]
[INDENT]customer_email varchar(30), [/INDENT]
[INDENT]customer_state varchar(2), [/INDENT]
[INDENT]primary key (id_num))[/INDENT]
now if you want to see all of the customer names for id_num's greater than 10, your query would look like this:
SELECT customer_name FROM customer WHERE id_num > 10;
Its that simple. To see everything in a table, you can use the * , i.e.
SELECT * FROM customer WHERE id_num > 10 AND customer_state = 'OK';
thats basically it.
