Answer 1

Try ::

Select *
from
user_ u
INNER JOIN user_roles ur on (u.userId = ur.userId)
INNER JOIN role_ r on (ur.roleId = r.roleId)

INNER JOIN users_organization uo (u.userId = uo.userId)
INNER JOIN organization_ o on (uo.organizationId= o.orgId)
where uo.org_id =? and  r.role_name=?

Answer 2

If I understand correctly (your question lacks the table relationships):

SELECT U.userId
    , U.userName
    FROM user_ U
    INNER JOIN users_organization UO ON UO.userId = U.userId
    INNER JOIN user_roles UR ON UR.userId = U.userId
    WHERE UO.organizationId = organizationId
        AND UR.roleName = roleName;

The parameters are organizationId and roleName.

Answer 3

Try it out below suggestion.

SELECT u.userName
FROM user_ u
   , role_ r
   , users_organization uo
   , user_roles ur
WHERE r.roleName = ?
  AND uo.organizationId = ?
  AND ur.userId = u.userId 
  AND ur.roleId = r.roleId 
  AND u.userId = uo.userId
