Question

I am using java/oracle. i have below issue.

SELECT
         DISTINCT id_one,
         status 
     FROM
         sometable 
     WHERE
         id_two IN (
             SELECT
                 DISTINCT id_two  
             FROM
                 othertable
         ) 
         AND id_one IN (1946,1948,1949)  

i have above query to fetch data from one table. inner query’s data from other table.
now i need add one where condition to inner query.
othertable has one more field called name.

these are the ids that i mentioned: 1946,1948,1949. here each id will have names as below: name1, name2, name3
name1, name2, name3 are passed from java application.

finally the query that i need as follows.

SELECT
         DISTINCT id_one,
         status 
     FROM
         sometable 
     WHERE
         id_two IN (
             SELECT
                 DISTINCT id_two  
             FROM
                 othertable other where other.name in('name1','name2','name3')
         ) 
         AND id_one IN (1946,1948,1949)  

my questions is: for 1946 id name1 should be considered and for 1948 id name2 should be considered
*and for 1949 id name3 should be considered as criteria.* i mean query should not consider all 3 names for every id.

how can i achieve it?

Answer 1

This can also be done like in the following way:

select distinct s.id_one, s.status
  from sometable s join othertable o on (s.id_two = o.id_two)
 where (s.id_one = 1946 and o.name = 'name1')
    OR (s.id_one = 1948 and o.name = 'name2')
    OR (s.id_one = 1949 and o.name = 'name3');
