范例

示例 #1 mysql_xdevapi\Table::count() 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");

$row $table->select('name''age')->execute()->fetchAll();

print_r($row);

以上例程的输出类似于:

Array
(
    [0] => Array
        (
            [name] => John
            [age] => 42
        )
    [1] => Array
        (
            [name] => Sam
            [age] => 33
        )
)
