We are trying to replace a 3rdparty where we don't know how they handled the reader part here. The query below is getting 197 * 2038017 row in the table.
In the below code we are trying to run the query and execute in the DB part and fetch and read the record. That is where it is failing.while loop not entered until executeSql returns (function returns an integer we don't check), resulting in entire result in memory.
Any help
If I limit the table to 1 or 2 rows or with lesser column say 50 record it works fine. Possible the malloc is bringing more data to fit in memory

mixed mysqli_fetch_row (mysqli_result $result)
Fetches one row of data from the result set and returns it as an enumerated array, where each column is stored in an array offset starting

Note
This function sets NULL fields to the PHP NULL value.
EXAMPLES

<?php
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s
", mysqli_connect_error());
exit();
}
$query = "SELECT Name, CountryCode FROM City ORDER by ID DESC LIMIT 50,5";
if ($result = $mysqli->query($query)) {
/* fetch object array */
while ($row = $result->fetch_row()) {
printf ("%s (%s)
", $row[0], $row[1]);
}
/* free result set */
$result->close();
}
/* close connection */
$mysqli->close();
?>
Example #2

<?php
$link = mysqli_connect("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s
", mysqli_connect_error());
exit();
}
$query = "SELECT Name, CountryCode FROM City ORDER by ID DESC LIMIT 50,5";
if ($result = mysqli_query($link, $query)) {
/* fetch associative array */
while ($row = mysqli_fetch_row($result)) {
printf ("%s (%s)
", $row[0], $row[1]);
}
/* free result set */
mysqli_free_result($result);
}
/* close connection */
