Oracle sql like multiple conditions with select from other table

Question

I have 375 dialcodes in table "temp":

917277
917278
918083
...
9172738

I can do the following:

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?

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

Answer 1

You can use JOIN and LIKE to achieve similiar result:

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 :

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.
