示例 #1 mysql_xdevapi\SqlStatementResult::fetchOne() example
<?php
$session = mysql_xdevapi\getSession("mysqlx://user:password@localhost");
$session->sql("DROP DATABASE IF EXISTS dbtest")->execute();
$session->sql("CREATE DATABASE dbtest")->execute();
$session->sql("CREATE TABLE dbtest.workers(name text, age int, job text)")->execute();
$session->sql("INSERT INTO dbtest.workers values ('John', 42, 'bricklayer'), ('Sam', 33, 'carpenter')")->execute();
$schema = $session->getSchema("dbtest");
$table = $schema->getTable("workers");
$rows = $session->sql("SELECT * FROM dbtest.workers")->execute()->fetchOne();
print_r($rows);
?>
以上例程的输出类似于:
Array ( [name] => John [age] => 42 [job] => bricklayer )
