假设你主键名称是Z,表为T
前一行:
select TOP1 Z from T where Z>'UUID' order by Z DESC
后一行:
select TOP1 Z from T where Z<'UUID' order by Z
合并:
在中间加 UNION ALL
这个不行就去查游标使用吧
您好,很高兴为您解答。
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]如若满意,请点击右侧【采纳答案】,如若还有问题,请点击【追问】
