示例 #1 mysql_xdevapi\RowResult::getColumnNames() example
<?php
$session = mysql_xdevapi\getSession("mysqlx://user:password@localhost");
$session->sql("DROP DATABASE addressbook")->execute();
$session->sql("CREATE DATABASE foo")->execute();
$session->sql("CREATE TABLE foo.test_table(x int)")->execute();
$session->sql("INSERT INTO addressbook.names values ('John', 42), ('Sam', 33)")->execute();
$sql = $session->sql("SELECT * from addressbook.names")->execute();
$colnames = $sql->getColumnNames();
print_r($colnames);
以上例程的輸出類(lèi)似于：
