Question

当我想从最后一行选择数据库的第一行时，我使用SELECT * FROM Gallery ORDER BY ID DESC，但我想选择从最后到第一行的第三行，例如这段代码：

$LastRowID = 20;

$FindRows = mysqli_query($Database,"SELECT * FROM Table ORDER BY ID DESC");
$FindLastRow = mysqli_query($Database,"SELECT * FROM Table Where ID = /* $LastRowID - 3 */ ORDER BY ID DESC");

当这段代码运行时，它只选择$ LastRowID - 3行，但我需要在$ LastRowID - 3之后选择所有行;

实现这个目标的方法是什么？

Answer 1

这是一种方式......

  SELECT * FROM ints;
  +---+
  | i |
  +---+
  | 0 |
  | 1 |
  | 2 |
  | 3 |
  | 4 |
  | 5 |
  | 6 |
  | 7 |
  | 8 |
  | 9 |
  +---+

  SELECT * FROM ints ORDER BY i DESC LIMIT 3,100000;
  +---+
  | i |
  +---+
  | 6 |
  | 5 |
  | 4 |
  | 3 |
  | 2 |
  | 1 |
  | 0 |
  +---+

Answer 2

SELECT x.* FROM
( SELECT * FROM Table ORDER BY Id DESC LIMIT 3) AS x
ORDER BY x.Id LIMIT 1

这会让你获得第三个最高ID的行。

如何在表格中间选择一行并选择之后的所有行？
