如何选择列的最高相对值？

Question

I want to select the row which has highest value in column "price" of the ones fullfilling the condition.

Using MAX() like shown below doesn't work for me since it's cehcking the highest absolute value of that column.

"SELECT * FROM parts_list WHERE " . (implode(' = 1 AND ', $utilization)) . " = 1 AND (part_price = (SELECT MAX(part_price) FROM parts_list))"

I only want it to select the one with the highest value for 'part_price' of the ones which fullfill:

 . (implode(' = 1 AND ', $utilization)) . " = 1 

Answer 1

您可以先ORDER BY part_price DESC ，然后使用TOP 1仅获得第一行。

Answer 2

发布后仅两分钟，我有了一个主意：

"SELECT MAX(part_price) * FROM parts_list WHERE " . (implode(' = 1 AND ', $utilization)) . " = 1 AND (part_price = (SELECT MAX(part_price) FROM parts_list WHERE ".implode(' = 1 AND ', $utilization)." = 1))");
