Support for this function is limited. See the feature compatibility matrix
mixed prepare ( string $sql )
prepare() prepares an SQL statement.
/* * Connection to Oracle database */ $handle = $db->prepare('SELECT * FROM customers WHERE customer_no=?'); $params = array(0=>100); /* * Send an array to execute */ $result = $db->execute(array($handle,$params));
For compatibility purposes, if the database does not support prepared statements, the SQL statement is returned into the
$handle variable. When sent to the
execute() function, The statement will be parsed to include the variables, and the statement will execute the same as if passed without parameters, and as if the DBMS supported prepared statements.
