    • 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:
