PDOStatement::execute

(no version information, might be only in CVS)

PDOStatement::execute -- Executes a prepared statement

Opis

bool PDOStatement::execute ( [array input_parameters] )

Execute the prepared statement. If the prepared statement included parameter markers, you must either:

call PDOStatement::bindParam() to bind PHP variables to the parameter markers: bound variables pass their value as input and receive the output value, if any, of their associated parameter markers
or pass an array of input-only parameter values

Parametry

input-parameters

An array of values with as many elements as there are bound parameters in the SQL statement being executed.

You cannot bind multiple values to a single parameter; for example, you cannot bind two values to a single named parameter in an IN() clause.

Zwracane wartości

Zwraca TRUE w przypadku sukcesu, FALSE w przypadku porażki.

Przykłady

Przykład 1. Execute a prepared statement with bound variables

<?php
/* Execute a prepared statement by binding PHP variables */

                $calories = 150;
$colour = 'red';
$sth = $dbh->prepare('SELECT name, colour, calories


                    FROM fruit

                    WHERE calories < :calories AND colour = :colour');

                $sth->bindParam(':calories', $calories, PDO::PARAM_INT);
$sth->bindParam(':colour', $colour, PDO::PARAM_STR, 12);
$sth->execute();
?>

Przykład 2. Execute a prepared statement with an array of insert values (named parameters)

<?php
/* Execute a prepared statement by passing an array of insert values */

                $calories = 150;
$colour = 'red';
$sth = $dbh->prepare('SELECT name, colour, calories


                    FROM fruit

                    WHERE calories < :calories AND colour = :colour');

                $sth->execute(array(':calories' => $calories, ':colour' => $colour));
?>

Przykład 3. Execute a prepared statement with an array of insert values (placeholders)

<?php
/* Execute a prepared statement by passing an array of insert values */

                $calories = 150;
$colour = 'red';
$sth = $dbh->prepare('SELECT name, colour, calories


                    FROM fruit

                    WHERE calories < ? AND colour = ?');

                $sth->execute(array($calories, $colour));
?>

Przykład 4. Execute a prepared statement with question mark placeholders

<?php
/* Execute a prepared statement by binding PHP variables */

                $calories = 150;
$colour = 'red';
$sth = $dbh->prepare('SELECT name, colour, calories


                    FROM fruit

                    WHERE calories < ? AND colour = ?');

                $sth->bindParam(1, $calories, PDO::PARAM_INT);
$sth->bindParam(2, $colour, PDO::PARAM_STR, 12);
$sth->execute();
?>
