Question

I need to write a hibernate criteria for this SQL:

select distinct USER_ID from USER_ROLE  
where USER_TERM_DT is null 
and ((ROLE_ID in (101,102) 
and STATE_ID in ('MD')) or ROLE_ID = 150)

The role_ids will have a combination of values (101,102,150,151)
The OR part only needs to be there if the Role_Id is 150 or 151.

The USER_ROLE table has Role_id & state_id. Only roles 101 & 102 are associated with state_ids.

If all the 4 role_id values are there, the SQL would be like:

select distinct USER_ID from USER_ROLE  
where USER_TERM_DT is null 
and ((ROLE_ID in (101,102) 
and STATE_ID in ('MD')) or ROLE_ID in (150,151))

Please help in this matter. I’m reading I need to use conjunction & disjunction together, but just not able to come up with the right code. Hope it’s clear & my SQL is right.

Answer 1

Something like this should work – replace the ‘is null’ and the ‘in’ expressions with the corresponding Restrictions

criteria.conjuction()
        .add(USER_TERM_DT is null )
        .add(criteria.disjuction().
                 add(
                   criteria.conjuction()
                            .add(ROLE_ID in (101,102) )
                            .add(STATE_ID in ('MD'))
                 )
                 .add(ROLE_ID in (150,151))
         )
