Example #1 mysql_xdevapi\TableSelect::__construct() 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', 33)")->execute();

$schema = $session->getSchema("addressbook");
$table  = $schema->getTable("names");

$result = $table->select('name','age')
  ->where('name like :name and age > :age')
  ->bind(['name' => 'John', 'age' => 42])
  ->orderBy('age desc')
  ->execute();

$row = $result->fetchAll();
print_r($row);

?>

以上例程的输出类似于：

Array
(
    [0] => Array
        (
            [name] => John
            [age] => 42
        )
)
