MySQL查询上一条记录和下一条记录

如果ID是主键或者有索引,可以直接查找:

方法一:

查询上一条记录的SQL语句(如果有其他的查询条件记得加上other_conditions以免出现不必要的错误):

select * from table_a where id = (select id from table_a where id < {$id} [and other_conditions] order by id desc limit 1) [and other_conditions];

查询下一条记录的SQL语句(如果有其他的查询条件记得加上other_conditions以免出现不必要的错误):

select * from table_a where id = (select id from table_a where id > {$id} [and other_conditions] order by id asc limit 1) [and other_conditions];

方法二:

查询上一条记录的SQL语句((如果有其他的查询条件记得加上other_conditions以免出现不必要的错误))

select * from table_a where id = (select max(id) from table_a where id < {$id} [and other_conditions]) [and other_conditions];

查询下一条记录的SQL语句(如果有其他的查询条件记得加上other_conditions以免出现不必要的错误):

select * from table_a where id = (select min(id) from table_a where id > {$id} [and other_conditions]) [and other_conditions];
