选择

Question

SELECT ID FROM TABLE WHERE ID BETWEEN 1 AND 5

上述查询的结果将是：1,2,3,4,5

如果表格中只有id 1和id 2，那么它只会循环(1,2)。

这意味着，如果id介于1 AND 5之间，则id的{​​{1}}不存在。

3,4,5的{​​{1}}是我想要选择的内容。这该怎么做？

Answer 1

试试这个：

select * from 
(
   select 1 as val
   union all
   select 2
   union all
   select 3 
   union all
   select 4
   union all
   select 5
)t
left join TableName tn on t.val = tn.id
where tn.id is null

使用tally table：

select * from (
select (3 + th*1000+h*100+t*10+u+1) x from
(select 0 th union select 1 union select 2 union select 3 union select 4 union
select 5 union select 6 union select 7 union select 8 union select 9) A,
(select 0 h union select 1 union select 2 union select 3 union select 4 union
select 5 union select 6 union select 7 union select 8 union select 9) B,
(select 0 t union select 1 union select 2 union select 3 union select 4 union
select 5 union select 6 union select 7 union select 8 union select 9) C,
(select 0 u union select 1 union select 2 union select 3 union select 4 union
select 5 union select 6 union select 7 union select 8 union select 9) D)
tn
left join t on tn.x = t.id
where tn.x between 3 and 10
and t.id is null

注意公式(3 + th*1000+h*100+t*10+u+1)和where第3条是srart，10是end。改变变量。
