Oracle SQL喜欢从其他表中选择的多个条件

Question

I have 375 dialcodes in table "temp": 我在表“ temp”中有375个拨号代码：

I can do the following: 我可以执行以下操作：

select * from cdr where 
dnis like 917277% or
dnis like 917278% or
dnis like 918083% or
...
dnis like 9172738%

Is it possible to make a query including "select in" and "like %" conditions? 是否可以进行包含“选择入”和“类似％”条件的查询？

select * from cdr where dnis in (select dialcode% from temp)

Answer 1

You can use JOIN and LIKE to achieve similiar result: 您可以使用JOIN和LIKE达到相似的结果：

SELECT c.*           -- DISTINCT may be needed if dialcodes overlap each other
FROM cdr c
JOIN temp t
  ON c.dnis LIKE t.dialcode || '%'

Answer 2

One method is to use exists : 一种方法是使用exists ：

select c.*
from cdr c
where exists (select 1 from temp t where c.dnis like dialcode || '%' );

Note that this does not require distinct , even when there might be multiple matches. 请注意，即使可能存在多个匹配项，也不需要distinct 。
