如果在SQL中有多個最大值，請選擇一行的ID

Question

我只想選擇item_id為1001的下表（table1）具有最高優先級的id。

表格1

id  | plan_id | item_id | plan_item_bundle_id | precedence 
-----+---------+---------+---------------------+------------

 401 |         |    1001 |                     |         -1

 402 |         |    1001 |                     |         -1

我該怎么做 ？ 謝謝

我不在乎優先級是否相同，任何人都可以。 謝謝

Answer 1

select id from table1
group by id, prededence
having precedence = max(precedence )
Limit 0, 1

Answer 2

試試這個查詢

select id from table1 where precedence =(select max(precedence) from table1)

Answer 3

您可以嘗試：

SELECT id FROM table1 
WHERE precedence = MAX(precedence)
  AND item_id = 1001
LIMIT 1

要么

SELECT id FROM table1 
WHERE precedence = (SELECT MAX(precedence) FROM table1)
  AND item_id = 1001
LIMIT 1
