(PHP 5, PECL sqlite >= 1.0.1)
sqlite_fetch_single -- SQLiteResult->fetchSingle -- SQLiteUnbuffered->fetchSingle — Fetches the first column of a result set as a string
Object oriented style (method):
sqlite_fetch_single() is identical to sqlite_fetch_array() except that it returns the value of the first column of the rowset.
This is the most optimal way to retrieve data when you are only interested in the values from a single column of data.
The SQLite result resource. This parameter is not required when using the object-oriented method.
Cuando el parámetro decode_binary es seteado a TRUE (el valor por defecto), PHP decodificará la codificación binaria que se aplicó a los datos si éstos fueron codificados usando la función sqlite_escape_string(). Normalmente debería dejar este valor por defecto, a menos que esté interoperando con bases de datos creadas por otras aplicaciones sqlite.
Returns the first column value, as a string.
Example #1 A sqlite_fetch_single() example
<?php
if ($dbhandle = sqlite_open('mysqlitedb', 0666, $sqliteerror)) {
$sql = "SELECT id FROM sometable WHERE id = 42";
$res = sqlite_query($dbhandle, $sql);
if (sqlite_num_rows($res) > 0) {
echo sqlite_fetch_single($res); // 42
}
sqlite_close($dbhandle);
}
?>
