Example 5.179 mysql_xdevapi\TableSelect::having 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
        )
)
