Create new table for each unique id
Hi guys, have a problem I am struggling with. I have a database table which contains the fields
id - PK
alert_id - FK
letter - Char
number - int(11)
last_updated - Timestamp
Sql query to select the data is just a basic select
$sql = "SELECT * FROM `alert_availability`;
table 1 <---alert_id A B C <----letter 01:00am <--last_updated 3 2 5 <----number 02:00am 5 4 0 table 2 <---alert_id F T R <----letter 01:00<--last_updated 2 5 6 <----number ... ...
Any advice appreciated as always.

You simply keep track of the last alert id and break the table whenever it changes. You need to ensure the query is sorted by the alert_id as well.
$lastid = null;
while ($row = $qry->fetch_assoc())
if ($lastid != $row['alert_id'])
if ($lastid != null)
$lastid = $row['alert_id'];
