我安装了新的 Ubuntu,但我的代码遇到了 MySQL 问题。
( ! ) Warning: PDOStatement::execute(): SQLSTATE[HY000]: General error: 3065
Expression #2 of ORDER BY clause is not in SELECT list, references column 'clicshopping_test_ui.p.products_date_added' which is not in SELECT list; this is incompatible with DISTINCT
in /home/www//boutique/includes/OM/DbStatement.php on line 97s
似乎 MySQL 5.7 不允许这样的请求:
select .... distinct with order by rand(), p.products_date_added DESC
如果我使用它,它会起作用:
select distinct .... with order by rand(),
如何解决这种情况?
我在 PHP 中的 SQL 请求
$Qproduct = $OSCOM_PDO->prepare('select distinct p.products_id,
p.products_price
from :table_products p left join :table_specials s on p.products_id = s.products_id
where products_status = :products_status
and products_view = :products_view
and p.products_archive = :products_archive
order by rand(),
p.products_date_added DESC
limit :products_limit');
$Qproduct->bindInt(':products_status', 1);
$Qproduct->bindInt(':products_view', 1);
$Qproduct->bindInt(':products_archive', 0);
$Qproduct->bindInt(':products_limit',
(int)MODULE_FRONT_PAGE_NEW_PRODUCTS_MAX_DISPLAY);
