如果ID是主键或者有索引,可以直接查找:
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];
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];
