我想问一下当我选择“8787”

时如何获取下一个和之前的数据

这是表名称的样本数据：

NameId不是自动编号。

NameID    RName
6767      Apple
8787      Hallow
8627      Orange

由于

Answer 1

要获取下一个ID，请丢弃所有不大的ID，按ID对表进行排序，以便下一个ID是第一个ID，然后只获取这一个记录：

SELECT *
FROM MyTable
WHERE NameID > 8787
ORDER BY NameID
LIMIT 1

类似于之前的ID：

SELECT *
FROM MyTable
WHERE NameID < 8787
ORDER BY NameID DESC
LIMIT 1

Answer 2

根据CL。的答案，如果你想在一个查询中全部使用它：

select a.*, 
  (select RName  
   from t1 b 
   where b.NameID < a.NameID 
   order by NameID desc limit 1) as prev_rname,
  (select NameID 
   from t1 b 
   where b.NameID < a.NameID 
   order by NameID desc limit 1) as prev_NameID,
  (select RName  
   from t1 c 
   where c.NameID > a.NameID 
   order by NameID asc  limit 1) as next_rname,
  (select NameID 
   from t1 d 
   where d.NameID > a.NameID 
   order by NameID asc  limit 1) as next_NameID
from t1 a
order by a.NameID;

选择Next和上一行数据SQLite
