问题 I am creating a simple query in mySql to insert some values from a form into my db. My question is simple, but in reference to the difference between binding variables vs specifying them into the sql statement. Binding: $query = "INSERT INTO test (name, lastName, price) VALUES (:name, :lastName, :price)"; $apply = $con -> prepare($query); $apply -> execute (array(':name'=>$name,':lastName'=>$lastName,':price=>$price')); Typical: $query = "INSERT INTO test (name, lastName, price) VALUES ($name

问题 I'm still learning PDO so I might of missed something but basically I'm trying to insert a row into a table and then select the generated id. I'm not sure if it likes both queries in one pdo statement. Here is the code I'm using to execute the SQL. public function ExecuteQuery($sql, $params = array()) { if($this->_handle == null) $this->Connect(); $query = $this->_handle->prepare($sql); foreach($params as $key => $value) { if(is_int($value)){ $query->bindValue(':'.$key, $value, \PDO::PARAM

问题 This question already has answers here : Can I mix MySQL APIs in PHP? (4 answers) Closed last year . I'm moving away from mysql and mysqli as many users on stackoverflow are constantly saying good things about it. I've made a database class and have tested this, this connects fine to the database. I've tried to update my prepared statements to match however I am in unfamiliar territory and have ended up getting the following error: Fatal error: Call to undefined method PDOStatement::bind

The only other solution I see is to either a) fetch the entire outer loop at once or b) open 2 different connections to the database. Neither of these seem

SQLSTATE[HY000]: General error: 1615 Prepared statement needs to be re-prepared (There is a discussion on Bug #42041 Prepared-Statement fails when MySQL-Server under load, as well as numerous questions on Stack Overflow.) For some reason, the query using the view runs just fine, if we switch to using the nd_pdo_mysql extension, which is for the MySQL Native
