===Select===

As a further example, suppose a database contains only the following table:
+
{| class="wikitable"
+
|-
+
! customer_id !! last_name !! first_name !! city
+
|-
+
| 10039 || Smith || John || Huston
+
|-
+
| 10178 || Cole || Christen || Wortham
+
|-
+
| 10052 || Franks || Andrew || Austin
+
|-
+
| 10131 || Klinfelt || Mark || Thornberry
+
|-
+
| 10014 || Franklin || Mary || Austin
+
|}
+
If the following query is run:
+
<pre>
+
SELECT *
+
FROM customers
+
WHERE city = 'Austin'
+
ORDER BY last_name ASC;
+
</pre>
+
+
then these results would be returned:
+
{| class="wikitable"
+
|-
+
! customer_id !! last_name !! first_name !! city
+
|-
+
| 10014 || Franklin || Mary || Austin
+
|-
+
| 10052 || Franks || Andrew || Austin
+
|}
