note 121996 added to class.pdo

For some Database Environment, such as Aliyun DRDS (Distributed Relational Database Service), cannot process preparing for SQL. For such cases, the option \PDO::ATTR_EMULATE_PREPARES should be set to true. If you always got reports about "Failed to prepare SQL" while this option were set to false, you might try to turn on this option to emulate prepares for SQL. ---- Server IP: 208.43.231.9 Probable Submitter: 125.121.196.14 ---- Manual Page -- http://php.net/manual/en/class.pdo.php Edit -- https://master.php.net/note/edit/121996 Del: integrated -- https://master.php.net/note/delete/121996/integrated Del: useless -- https://master.php.net/note/delete/121996/useless Del: bad code -- https://master.php.net/note/delete/121996/bad+code Del: spam -- https://master.php.net/note/delete/121996/spam Del: non-english -- https://master.php.net/note/delete/121996/non-english Del: in docs -- https://master.php.net/note/delete/121996/in+docs Del: other reasons-- https://master.php.net/note/delete/121996 Reject -- https://master.php.net/note/reject/121996 Search -- https://master.php.net/manage/user-notes.php
