示例 #1 mysql_xdevapi\RowResult::fetchOne() example
<?php
$session = mysql_xdevapi\getSession("mysqlx://user:password@localhost");
$session->sql("DROP DATABASE 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 = $table->select('name', 'age')->where('age < 40')->execute()->fetchOne();
print_r($row);
以上例程的输出类似于:
Array ( [name] => Sam [age] => 33 )
