To select only data that matches a specified criteria, add a WHERE clause to the SELECT statement. -------------------------------------------------------------------------------- [color=FA0309]The WHERE clause[/color]
To select only data that matches a specific criteria, add a WHERE clause to the SELECT statement. [color=FA0309]Syntax[/color]
SELECT column FROM table
WHERE column operator value
The following operators can be used with the WHERE clause:

i

Note: SQL statements are not case sensitive. WHERE is the same as where. To get PHP to execute the statement above we must use the mysql_query() function. This function is used to send a query or command to a MySQL connection. [color=FA0309]Example[/color]
The following example will select all rows from the 'Person' table, where FirstName='Peter':
<?php
$con = mysql_connect('localhost','peter','abc123');
if (!$con)
{
die('Could not connect: ' . mysql_error());
} mysql_select_db('my_db', $con); $result = mysql_query('SELECT * FROM person
WHERE FirstName='Peter''); while($row = mysql_fetch_array($result))
{
echo $row['FirstName'] . ' ' . $row['LastName'];
echo '<br />';
} ?>
The output of the code above will be:
