SQL: SELECT Statement


The SELECT statement allows you to retrieve records from one or more tables in your database.
The syntax for the SELECT statement is:
SELECT columns FROM tables WHERE predicates;

Example #1 : Let's take a look at how to select all fields from a table.

SELECT * FROM suppliers
WHERE city = 'Newark';


In our example, we've used * to signify that we wish to view all fields from the suppliers table where the supplier resides in Newark.

Example #2 : You can also choose to select individual fields as opposed to all fields in the table.
For example:


SELECT name, city, state FROM suppliers

WHERE supplier_id > 1000;


This select statement would return all name, city, and state values from the suppliers table where the supplier_id value is greater than 1000.

Example #3 : You can also use the select statement to retrieve fields from multiple tables.


SELECT orders.order_id, suppliers.name FROM suppliers, orders
WHERE suppliers.supplier_id = orders.supplier_id;


The result set would display the order_id and suppier name fields where the supplier_id value existed in both the suppliers and orders table.
