Alternative to FIND_IN_SET in SQLite?
In Mysql, FIND_IN_SET
is used to find value in a set. I have tried FIND_IN_SET
in SQLite, but it is not an SQL keyword. I have Googled, but I did not get an a开发者_如何学编程nswer. If anybody knows, please tell me the alternative to FIND_IN_SET
in SQLite.
If you need just a true / false value rather than index then you can use LIKE
clause:
(',' || column_name || ',') LIKE '%,value,%'
we can write query like change into hibernate critearea
my old query
select * FROM game_detail WHERE content_id=176 and FIND_IN_SET(12,group_master_id)
New query
select *
FROM game_detail
WHERE content_id=176
and (group_master_id LIKE '%12,%'|| group_master_id LIKE '%,12,'|| group_master_id LIKE '%12')
This is my old query
String query = "SELECT a.content_id,a.content_name,a.image_name,a.image_path,a.rating,d.content_type_name"
+ "from content_master a, category_content_mapping b, "
+ "game_detail c, content_type_master d "
+ "where a.content_id=b.content_id "
+ "and c.content_id = a.content_id "
+ "and a.content_type_id = d.content_type_id "
+ "and b.category_id = '" + category_id + "' "
+ "and find_in_set('" + group_master_id + "',c.group_master_id) "
+ "and a.is_active='Y' and b.is_active = 'Y' and c.is_active = 'Y'"
+ "order by b.content_mapping_id DESC limit 0,3";
Criteria in hibernate use like alternate of find_in_set
Session session=new Configuration().configure().buildSessionFactory().openSession();
Criteria criteria=session.createCriteria(ContentMaster.class);
criteria.setFetchMode("CategoryContentMapping", FetchMode.JOIN);
criteria.setFetchMode("GameDetail", FetchMode.JOIN);
criteria.createAlias("categoryContentMappings","cat");
criteria.createAlias("contentTypeMaster", "ctm");
criteria.createAlias("gameDetails","game");
criteria.add(Restrictions.eq("cat.categoryMaster.categoryMasterId", 9));
criteria.add(Restrictions.disjunction()
.add(Restrictions.like("game.groupMasterId","%12,%"))
.add(Restrictions.like("game.groupMasterId","%,12,%"))
.add(Restrictions.like("game.groupMasterId","%12%")));
criteria.add(Restrictions.eq("isActive", "y"));
criteria.add(Restrictions.eq("cat.isActive", "y"));
criteria.add(Restrictions.eq("ctm.isActive", "y"));
criteria.addOrder(Order.desc("cat.contentMappingId"));
