PDO update query with conditional?
- by dmontain
I have a PDO mysql that updates 3 fields.
$update = $mypdo->prepare("UPDATE tablename SET field1=:field1,
field2=:field2,
field3=:field3
WHERE key=:key");
But I want field3 to be updated only when $update3 = true; (meaning that the update of field3 is controlled by a conditional statement)
Is this possible to accomplish with a single query?
I could do it with 2 queries where I update field1 and field2 then check the boolean and update field3 if needed in a separate query.
//run this query to update only fields 1 and 2
$update_part1 = $mypdo->prepare("UPDATE tablename SET field1=:field1,
field2=:field2
WHERE key=:key");
//if field3 should be update, run a separate query to update it separately
if ($update3){
$update_part2 = $mypdo->prepare("UPDATE tablename SET field3=:field3
WHERE key=:key");
}
But hopefully there is a way to accomplish this in 1 query?
