An SQL select statement is used to select certain rows from a table or tables. A select query will return as many rows as match the criteria.
select field1 [, field2, field3] from table1 [, table2] where condition order by field [desc]
select id, name from customer; select id, name from customer order by name; select id, name from customer order by name desc;
We can use a select statement to obtain data from multiple tables. This is referred to as a ``join''.
select * from customer, sales where customer.id = sales.customer_id
