PDOStatement::execute

(PHP 5 >= 5.1.0, PECL pdo >= 0.1.0)

PDOStatement::execute Executes a prepared statement

Descrição

public bool PDOStatement::execute ([ array $input_parameters ] )

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

Parâmetros

input_parameters

An array of values with as many elements as there are bound parameters in the SQL statement being executed. All values are treated as PDO::PARAM_STR.

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.

You cannot bind more values than specified; if more keys exist in input_parameters than in the SQL specified in the PDO::prepare(), then the statement will fail and an error is emitted.

Valor Retornado

Retorna TRUE em caso de sucesso ou FALSE em caso de falha.

Changelog

Versão Descrição
5.2.0 The keys from input_parameters must match the ones declared in the SQL. Before PHP 5.2.0 this was silently ignored.

Exemplos

Exemplo #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'
);
$sth->bindParam(':calories'$caloriesPDO::PARAM_INT);
$sth->bindParam(':colour'$colourPDO::PARAM_STR12);
$sth->execute();
?>

Exemplo #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));
?>

Exemplo #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));
?>

Exemplo #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 = ?'
);
$sth->bindParam(1$caloriesPDO::PARAM_INT);
$sth->bindParam(2$colourPDO::PARAM_STR12);
$sth->execute();
?>

Exemplo #5 Execute a prepared statement using array for IN clause

<?php
/* Execute a prepared statement using an array of values for an IN clause */
$params = array(12163171);
/* Create a string for the parameter placeholders filled to the number of params */
$place_holders implode(','array_fill(0count($params), '?'));

/*
    This prepares the statement with enough unnamed placeholders for every value
    in our $params array. The values of the $params array are then bound to the
    placeholders in the prepared statement when the statement is executed.
    This is not the same thing as using PDOStatement::bindParam() since this
    requires a reference to the variable. PDOStatement::execute() only binds
    by value instead.
*/
$sth $dbh->prepare("SELECT id, name FROM contacts WHERE id IN ($place_holders)");
$sth->execute($params);
?>
