问题描述

如何从表中选择第一,第三,第十一和第n行?

How to select 1st, 3rd, 11th and nth row from a table?

推荐答案

如果为表定义的主键是基于整数的数据类型-例如MySQL和SQLite都具有auto_increment,则可以使用:

If there is a primary key defined for the table that is an integer based data type--both MySQL and SQLite have auto_increment for example--then you can use:

SELECT t.*
  FROM TABLE t
 WHERE t.id IN (1,3, 11)

...其中id是auto_increment列.

...where id is the auto_increment column.

几乎没有什么细节可做,但是MySQL和SQLite没有分析查询支持,这使得查询相当复杂:

There's very little detail to go on, but MySQL and SQLite do not have analytic query support, making queries rather complicated:

SELECT y.*
  FROM (SELECT t.*,
                        (SELECT COUNT(*)
                            FROM TABLE x
                           WHERE x.col <= t.col) AS rank
               FROM TABLE t) y
 WHERE y.rank IN (1, 3, 11)
