Question

SELECT * FROM TableName WHERE name='test'

执行上述查询后，我想要上一个和下一个id值。当然，他们不会增量。如何根据where条件获取下一个和上一个id。

Answer 1

尝试以下

 select * from Tablename where name = 'test' AND id = (select min(id) from Tablename  where id > 4) OR id = (select max(id) from Tablename  where id < 4)

Answer 2

SELECT
    * 
FROM
    TableName 
WHERE 
    id = (SELECT MIN(id) FROM TableName where id > 2) 
    AND id = (SELECT MAX(id) FROM TableName where id < 2)

或您可以使用Limit

SELECT * FROM TableName WHERE `id` > 2 ORDER BY `id` ASC LIMIT 1
UNION 
SELECT * FROM TableName WHERE `id` < 2 ORDER BY `id` DESC LIMIT 1

Answer 3

我相信如果您使用的是php

，可以使用mysql_data_seek（）

得到以前的＆amp; mysql查询的下一个id值
