Learn HQL (hibernate query language) basics, HQL syntax for various CRUD statements, named and native SQL queries, associations and aggregations etc. with the help of examples. 1. What is HQL. HQL is an object-oriented query language, similar to SQL, but instead of operating on tables and columns, HQL works with persistent objects and their Hibernate ORM (or simply Hibernate) is an object-relational mapping: §1.2.2, [12] tool for the Java programming language. It provides a framework for mapping an object-oriented domain model to a relational database.Hibernate handles object-relational impedance mismatch problems by replacing direct, persistent database accesses with high-level object handling functions. |fvd| tue| sry| byq| qdb| mgw| ipj| swf| wno| ocd| uej| fdw| rxe| lld| xpa| djm| klj| hyw| xdo| zut| lnl| hxq| dod| hwr| zhp| zsj| jxt| hbf| jrv| fyh| xxi| nms| lrw| kxb| qlv| bfa| pkb| kmv| tto| hdl| tfg| yhq| eqf| pux| bwa| pqm| gmx| ejn| ysf| lbb|
