Dynamically setting schema name for native queries in hbm file.
In the IDE you can construct and test queries based on the Hibernate Query Language (HQL) using the HQL Query Editor. As you type the query the editor shows the equivalent (translated) SQL query. When you click the 'Run HQL Query' button in the toolbar, the IDE executes the query and shows the results at the bottom of editor.
The way that you wrote the query it seems to be an SQL query and not an HQL query. Using session.createQuery, you need to provide to this method a HQL query, and not a SQL query. You can use session.createSQLQuery with a SQL query, or write your query as a HQL query, something like: select cv.field from table1 alias1 JOIN alias1.x.
In the mapping tag of the hibernate.cfg file, TestTable was defined in the class attribute that represent a pojo class class, being referred to the database table. The TestTale.Java File: This file defines a pojo class that is bean class having setter and getter methods for defines class variables.
Hibernate not only takes care of the mapping from Java classes to database tables (and from Java data types to SQL data types), but also provides data query and retrieval facilities. It can significantly reduce development time otherwise spent with manual data handling in SQL and JDBC.
In this tutorial, I am going to use Product table and inserting records into product table via native query with HQL. Although we have already seen an example of fetching records using Hibernate Query Language here. Native Sql Query: Hibernate provides SQLQuery interface to execute Sql Query and SQLQuery can be obtain via createSQLQuery method.
I too face the same issue as you told, i am using sql-query in my hbm and instead of getting my specified Mailbox Object, i am getting collection of Object. Can you tell me how to write the same peice of SQL in HQL and to retrieve my specified Object my hbm file is as below:-.
HQL query translated to SQL After you reverse-engineer a database, you are ready to start writing your application to read, write, and update objects in your database. When you have your Java classes and methods in place, you can run a Hibernate query in the HQL editor to query the database.
