db2_bind_param

Beschreibung

Binds a PHP variable to an SQL statement parameter in a statement resource returned by db2_prepare(). This function gives you more control over the parameter type, data type, precision, and scale for the parameter than simply passing the variable as part of the optional input array to db2_execute().

Beispiele

Beispiel 1. Binding PHP variables to a prepared statement The SQL statement in the following example uses two input parameters in the WHERE clause. We call db2_bind_param() to bind two PHP variables to the corresponding SQL parameters. Notice that the PHP variables do not have to be declared or assigned before the call to db2_bind_param(); in the example, $lower_limit is assigned a value before the call to db2_bind_param(), but $upper_limit is assigned a value after the call to db2_bind_param(). The variables must be bound and, for parameters that accept input, must have any value assigned, before calling db2_execute(). <?php $sql = 'SELECT name, breed, weight FROM animals     WHERE weight > ? AND weight < ?'; $conn = db2_connect($database, $user, $password); $stmt = db2_prepare($conn, $sql); // We can declare the variable before calling db2_bind_param() $lower_limit = 1; db2_bind_param($stmt, 1, "lower_limit", DB2_PARAM_IN); db2_bind_param($stmt, 2, "upper_limit", DB2_PARAM_IN); // We can also declare the variable after calling db2_bind_param() $upper_limit = 15.0; if (db2_execute($stmt)) {     while ($row = db2_fetch_array($stmt)) {         print "{$row[0]}, {$row[1]}, {$row[2]}\n";         } } ?> Das oben gezeigte Beispiel erzeugt folgende Ausgabe: Pook, cat, 3.2 Rickety Ride, goat, 9.7 Peaches, dog, 12.3
