Connection

exec

See https://www.php.net/manual/en/pdo.exec.php.

$count = $connection->exec("DELETE FROM users");

query

See https://www.php.net/manual/en/pdo.query.php.

$pdo_stmt = $connection->query("SELECT * FROM users");
$pdo_stmt = $connection->query("SELECT * FROM users", $fetchMode, ...$fetchModeArgs);

prepare

See https://www.php.net/manual/en/pdo.prepare.php.

$pdo_stmt = $connection->prepare("SELECT * FROM users WHERE id = ?");
$pdo_stmt = $connection->prepare("SELECT * FROM users WHERE id = ?", $options);

execute

See https://www.php.net/manual/en/pdostatement.execute.php.

$pdo_stmt = $connection->execute("SELECT * FROM users WHERE id = ?", [1]);

fetch

See https://www.php.net/manual/en/pdostatement.fetch.php.

$user = $connection->fetch("SELECT * FROM users WHERE id = ?", [1]);
$user = $connection->fetch("SELECT * FROM users WHERE id = ?", [1], $mode, $cursorOrientation, $cursorOffset);

fetchAll

See https://www.php.net/manual/en/pdostatement.fetchall.php.

$users = $connection->fetchAll("SELECT * FROM users WHERE status = ?", [1]);
$users = $connection->fetchAll("SELECT * FROM users WHERE status = ?", [1], $mode, ...$args);

fetchColumn

See https://www.php.net/manual/en/pdostatement.fetchcolumn.php

$id = $connection->fetchColumn("SELECT * FROM users WHERE id = ?", [1]);
$id = $connection->fetchColumn("SELECT * FROM users WHERE id = ?", [1], $column);

fetchObject

See https://www.php.net/manual/en/pdostatement.fetchobject.php

$user = $connection->fetchObject("SELECT * FROM users WHERE id = ?", [1]);
$user = $connection->fetchObject("SELECT * FROM users WHERE id = ?", [1], $class, $constructorArgs);

yield

See https://www.php.net/manual/en/pdostatement.fetch.php.

$generator = $connection->yield("SELECT * FROM users WHERE status = ?", [1]);
$generator = $connection->yield("SELECT * FROM users WHERE status = ?", [1], $mode, $cursorOrientation, $cursorOffset);

transaction

Begins a transaction, rolls back if an exception is thrown (rethrowing the exception), else commits.

use MichaelRushton\DB\Connection;

$connection->transaction(function (Connection $connection)
{
    $connection->query("INSERT INTO users (id) VALUES (1)");
    $connection->query("INSERT INTO users (id) VALUES (2)");
});
