使用 Medoo 连接表格 (MySQL)

Joining tables with Medoo (MySQL)

我对数据库不太熟悉,我 运行 遇到了必须使用 join.

的情况

products table:

╔════════════╦═════════╦═════════════════╗
║ product_id ║   MPN   ║ manufacturer_id ║
╠════════════╬═════════╬═════════════════╣
║         51 ║ GB40337 ║              11 ║
╚════════════╩═════════╩═════════════════╝

manufacturers table:

╔═════════════════╦═════════╗
║ manufacturer_id ║  name   ║
╠═════════════════╬═════════╣
║              11 ║ Griffin ║
╚═════════════════╩═════════╝

据我了解,需要内部联接才能获取制造商名称?所以我 运行 这个查询:

SELECT product.mpn, manufacturer.name
FROM product
INNER JOIN manufacturer
ON product.manufacturer_id=manufacturer.manufacturer_id;

它 returns 数据正确,但现在因为我正在使用 Medoo 我必须使用它的语法,我不太明白:http://medoo.in/api/select

如何使用 medoo 进行相同的查询?

试试这个

$database->select("product", [
            "[><]manufacturer" => ["manufacturer_id" => "manufacturer_id"]], [
            "product.mpn",
            "manufacturer.name"]);

在 Medoo 中你可以这样写你的查询。

$db->select(
    'product', 
    array('[><]manufacturer' => array('product.manufacturer_id' => 'manufacturer.manufacturer_id')),
    array('product.mpn', 'manufacturer.name')
);
