I am running a PHP script to connect to MsSQL and execute a long running stored procedure. That procedure expects an ID which I pass in through this script. I loop over all the ID array and call this procedure. However for some IDs this procedure takes lot of time to run and times out. I set the ATTR_TIMEOUT PDO property to 600s. I have all the PDO statements inside a try catch block. Still, I get this uncaught exception. Here is my sample code: (Please ignore the new_statement params. I used dummies here. Its a valid one and runs fine)

try {

$statement = PDO::new_statement('DB', $sql, 0, false, false, [PDO::ATTR_TIMEOUT => 600]);

$this->execute($statement);

} catch (Exception $e) {

$logger->error("Error for ID: " . $id);

}

This works perfectly for most of the IDs. It fails for some long running IDs. If there is a TIMEOUT issue with executing the query, I would expect the error to be logged. However I see this exception:

PHP Fatal error: Uncaught HY000
["HY000",20003,"Adaptive Server connection timed out [20003] (severity 6)

Could someone please help me with this.

Pass the options to the PDO constructor:

$pdo = new PDO(

    "mysql:host=$host;dbname=$dbname", 

    $username, 

    $password,

    array(

        PDO::ATTR_TIMEOUT => "(seconds)",

        PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION

    )

);

if that doesn't help, you can try to set connect_timeout manually in php.ini or use ini_set()

mysql.connect_timeout = "(seconds)"

If the driver uses sockets for the basic connection, and to set timeouts, you need to use the socket (stream) timeout function

ini_set("default_socket_timeout", "(seconds)");

You should also know that

PDO::ATTR_TIMEOUT: Specifies the timeout duration in seconds. Not all
drivers support this option, and its meaning may differ from driver to
driver. For example, sqlite will wait for up to this time value before
giving up on obtaining an writable lock, but other drivers may
interpret this as a connect or a read timeout interval.
