Im试图复制一个表的名称，其中id_lang在Prestashop中不同。
我想实现的是，我将同一个表中的名称从id_lang=6复制到id_lang=8 所在的名称
我有一个运行良好的SQL查询，但我想用PHP查询来实现，这样我就可以在上面放一个cron
有谁能帮我吗？
UPDATE ps_product_lang a
INNER JOIN ps_product_lang b
ON b.id_product = a.id_product
AND b.id_lang = 6
AND a.id_product > 2218
SET a.name = b.name
WHERE a.id_lang = 8
以下是您的查询：
Db::getInstance(_PS_USE_SQL_SLAVE_)->execute(
"UPDATE `" . _DB_PREFIX_ . "product_lang` a
INNER JOIN `" . _DB_PREFIX_ . "product_lang` b
ON b.id_product = a.id_product
AND b.id_lang = 6
AND a.id_product > 2218
SET a.name = b.name
WHERE a.id_lang = 8"
);
如果你想创建一个cron，这里是你的php文件：
<?php
// Put the real path to config.inc.php depending on the location of this file
include_once ('../../config/config.inc.php');
try {
$result = Db::getInstance(_PS_USE_SQL_SLAVE_)->execute(
"UPDATE `" . _DB_PREFIX_ . "product_lang` a
INNER JOIN `" . _DB_PREFIX_ . "product_lang` b
ON b.id_product = a.id_product
AND b.id_lang = 6
AND a.id_product > 2218
SET a.name = b.name
WHERE a.id_lang = 8"
);
} catch (PrestaShopDatabaseException $e) {
// You might need to get some more informations on this error
// $error = $e->getMessage();
$result = false;
}
echo $result ? "ok" : "ko";
