mysql查询下一条数据的方法：

获取当前文件下一条记录的原理是下一条的sql语句，从news表里按从小到大的顺序选择一条比当前ID大的数据。

如果ID是主键或者有索引，可以直接查找：

方法1：

复制代码1.select * from table_a where id = (select id from table_a where id < {$id} order by id desc limit 1);   
2.select * from table_a where id = (select id from table_a where id > {$id} order by id asc limit 1);1
2
1.select * from table_a where id = (select id from table_a where id < {$id} order by id desc limit 1);   
2.select * from table_a where id = (select id from table_a where id > {$id} order by id asc limit 1);
登录后复制

方法2：

复制代码1.select * from table_a where id = (select max(id) from table_a where id < {$id});   
2.select * from table_a where id = (select min(id) from table_a where id > {$id});1
2
1.select * from table_a where id = (select max(id) from table_a where id < {$id});   
2.select * from table_a where id = (select min(id) from table_a where id > {$id});
