Hibernate Query to fetch records on date ignoring timestamp

由 岁酱吖の 提交于 2019-12-06 07:04:08
I have a timestamp column tradedate in one of the DB(Oracle) tables. I am using hibernate as the persistence layer to fetch and store Data to DB. I have a requirement in which I need to query the DB on date. i.e From UI the user passes a date and I need to get the filtered data based on this date. If the tradedate column only has the date part my query returns the correct records The issue arises when the tradedate column is populated with a timestamp value ie(date + time). Then those values are not returned by the query. eg:say there are 10 records for 23rd Oct 2010 in DB 5 of them have the

Hibernate throws NullPointerException from HqlSqlWalker

问题 I have a web application, which has a search form and HQL is generated on the fly. Also, user can click on the column headers to sort items as needed. Some columns get ther data from very deep down the structure. I have this HQL, for example, which works flawlessly: SELECT s FROM Application s LEFT JOIN s.product AS product LEFT JOIN product.originCountry AS origin WHERE s.nr = ? ORDER BY origin.name ASC But this one fails miserably: SELECT s FROM Application s LEFT JOIN s.product AS product

Round to 2 decimal places in hibernate query language

由 此生再无相见时 提交于 2019-12-06 06:26:56
Hi can someone help me how to round to 2 decimal places in hql? I can't find anything online.

HQL right outer join

由 ＊爱你＆永不变心＊ 提交于 2019-12-06 06:11:41
I am trying to perform right outer join in HQL. Query creation is done as mentioned below: Query query = this.sessionFactory .getCurrentSession() .createQuery( "select O.customer.id as id, O.customer.firstName as firstName, O.customer.lastName as lastName, O.customer.address as address, O.customer.city as city, count(O.id) as totalOrders from Order O right outer join O.customer group by O.customer.id"); SQL query on mysql is working fine, but the HQL query is returning the result for inner join. SQL query is: select c.id, c.firstname, c.lastname, c.city, count(o.id) as total_order from orders

问题 I have recently started using Spring boot, and have run into a bit of a problem. before, when i was just using Spring data with hibernate and JPA, I could create a hibernate.cfg.xml file that would give a bunch of configuration that could be passed to a config object and then ultimately create a SessionFactory object that would create a Session object that could be used to pass the query to hibernate: package util; import org.hibernate.SessionFactory; import org.hibernate.boot.registry
