example
<?php
$session = mysql_xdevapi\getSession("mysqlx://user:password@localhost");
$session->sql("DROP DATABASE IF EXISTS addressbook")->execute();
$session->sql("CREATE DATABASE addressbook")->execute();
$session->sql("CREATE TABLE addressbook.names(name text, age int)")->execute();
$session->sql("INSERT INTO addressbook.names values ('John', 42), ('Sam', 42)")->execute();
$session->sql("INSERT INTO addressbook.names values ('Suki', 31)")->execute();
$schema = $session->getSchema("addressbook");
$table = $schema->getTable("names");
$result = $table->select('count(*) as count', 'age')
->groupBy('age')->orderBy('age asc')
->having('count > 1')
->execute();
$row = $result->fetchAll();
print_r($row);
?>
The above example will output something similar to:
Array
(
[0] => Array
(
[count] => 2
[age] => 42
)
)
