having

In my CakePHP (1.2) app, I have two actions that both use pagination - index and search. In a previous question I learnt that, in order to apply a threshold score to search results, I need to use the HAVING MySQL keyword. Since CakePHP does not support this natively, I need to drop down to a custom query in order to accomplish this. All the guides I can find to custom query pagination involve overriding the paginate() and paginateCount() methods. Since I still want to be able to paginate normally on the index however, I don't want to change the normal pagination behaviour in the model. Is

I have two tables: groups and group_members . The groups table contains all the information for each group, such as its ID, title, description, etc. In the group_members table, it lists all the members who are apart of each group like this: group_id | user_id 1 | 100 2 | 23 2 | 100 9 | 601 Basically, I want to list THREE groups on a page, and I only want to list groups which have MORE than four members. Inside the <?php while ?> loop, I then want to four members who are apart of that group. I'm having no trouble listing the groups, and listing the members in another internal loop, I just

The following criteria query calculates the average of rating of different groups of products. CriteriaBuilder criteriaBuilder=entityManager.getCriteriaBuilder(); CriteriaQuery<Tuple>criteriaQuery=criteriaBuilder.createQuery(Tuple.class); Metamodel metamodel=entityManager.getMetamodel(); EntityType<Product>entityType=metamodel.entity(Product.class); Root<Product>root=criteriaQuery.from(entityType); SetJoin<Product, Rating> join = root.join(Product_.ratingSet, JoinType.LEFT); Expression<Number> quotExpression = criteriaBuilder.quot(criteriaBuilder.sum(join.get(Rating_.ratingNum)),

For what would be this query in SQL (to find duplicates): SELECT userId, name FROM col GROUP BY userId, name HAVING COUNT(*)>1 I performed this simple query in MongoDB: res = db.col.group({key:{userId:true,name:true}, reduce: function(obj,prev) {prev.count++;}, initial: {count:0}}) I've added a simple Javascript loop to go over the result set, and performed a filter to find all the fields with a count > 1 there, like so: for (i in res) {if (res[i].count>1) printjson(res[i])}; Is there a better way to do this other than using javascript code in the client? If this is the best/simplest way, say

I've written a query using Hibernate Criteria API to grab a summation of a particular value, now I need to be able to restrict the result to rows where that sum is greater or equal to a particular value. Normally I would use a HAVING clause in my SQL to do this, but the Criteria API doesn't seem to support that at this moment. In raw SQL this is what I need it to do: SELECT user_pk, sum(amount) as amountSum FROM transaction GROUP BY user_pk HAVING amountSum >=50; One work-around that I thought of is to use a subquery in the FROM clause that grabs this summation value and use an outer query to
