Incorrect MySQL query update - php

Question

I would like to filtering database records if there is duplicate records I will mark the records as deleted = 1. Unfortunately I'm not able to update my records correctly, I did try use limit 1 for updating the records but I only update 1 record only and if I didn't use the limit 1 it will update entire records.
The above is my database table, what I need to do is, assume there is bunch of records with different point_id and I filtered to 1 only. Now I would like to query the records sort by date ASC and update all the records to deleted = 1 expect the last record.
Here is my source code. The problem I facing now is it will update all the records, and if I using LIMIT 1 it only will update 1 record only.
while($total > 1){
$total--;
$sql = sprintf("SELECT *
FROM customers_profiles_game_logs
WHERE point_id='$points_filter_row[point_id]'
AND customer_id='$sql_customer_row[customer_id]'
ORDER BY date_created ASC");
$query = mysql_query($sql) or die(mysql_error());
$row = mysql_fetch_array($query);
$num_rows = mysql_num_rows($query);
for ($i = 1; $i < $num_rows; $num_rows--) {
echo $sqli = sprintf("UPDATE customers_profiles_game_logs
SET deleted='1'
WHERE customer_id='$sql_customer_row[customer_id]'
AND point_id='$row[point_id]' LIMIT 1");
mysql_query($sqli) or die(mysql_error());
}
}

Answer 1

You can have a subquery which gets the record to be updated and join it with the table itself, eg.
UPDATE customers_profiles_game_logs a
INNER JOIN
(
SELECT customer_id, MIN(date) date
FROM customers_profiles_game_logs
WHERE customer_id = 1 -- <== ID HERE
) b ON a.customer_id = b.customer_id
AND a.date = b.date
SET a.deleted = 1
if you remove the WHERE clause inside the subquery, all the first record for each customer will be updated.

Answer 2

you need this:
UPDATE customers_profiles_game_logs a
INNER JOIN
(
SELECT customer_id, MIN(date) date
FROM customers_profiles_game_logs
WHERE customer_id = 1 -- <== ID HERE
) b ON a.customer_id = b.customer_id
SET a.deleted = 1

another style:
UPDATE customers_profiles_game_logs a
INNER JOIN
(
SELECT customer_id, MIN(date) date
FROM customers_profiles_game_logs
) b ON a.customer_id = b.customer_id
SET a.deleted = 1
