$query = mysql_query("UPDATE a SET fruit = '**apple**' WHERE id = '**1**' ");
$query2 = mysql_query("UPDATE a SET fruit = '**orange**' WHERE id = '**2**' ");
$query3 = mysql_query("UPDATE a SET fruit = '**peach**' WHERE id = '**3**' ");

is there any way to simplify it to one query?

I found a following solution:

INSERT into `table` (id,fruit)
    VALUES (1,'apple'), (2,'orange'), (3,'peach')
    ON DUPLICATE KEY UPDATE fruit = VALUES(fruit);

Id must be unique or primary key. But don't know about performance.
