此函数没有参数。
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
)
)
