mysql - 如何只选择 MySQL 查询中的最后一个值？

Question

如何在 MySQL 上选择此结果的最后一个值：

这是查询的结果：

SELECT * from transaction WHERE transaction_id = 2

我只需要最后一个值3 300 2

 bank_id    amount   transaction_id
  1           800         2
  3           50          2
  3           300         2

Answer 1

如果bank_id不是唯一的并且您想首先选择最高金额的记录，您可以尝试这个：

SELECT *
  FROM transaction
 WHERE transaction_id = 2
 ORDER BY bank_id DESC
        , amount DESC
 LIMIT 1

看到这个 SQLFiddle

Answer 2

SELECT *
FROM transaction
WHERE transaction_id = 2
ORDER BY bank_id desc
LIMIT 1

  Join (SELECT @curRow := 0) r
 where Transaction_id = 2
 order by row_number desc
 limit 1
