Hibernate Stored Procedure call

Hibernate call store procedure
In Hibernate, there are three approaches to call a database store procedure.

1. Native SQL – createSQLQuery
You can use createSQLQuery() to call a store procedure directly.

Query query = session.createSQLQuery(
"CALL GetStocks(:stockCode)")
.addEntity(Stock.class)
.setParameter("stockCode", "7277");

List result = query.list();
for(int i=0; i Stock stock = (Stock)result.get(i);
System.out.println(stock.getStockCode());
}
2. NamedNativeQuery in annotation
Declare your store procedure inside the @NamedNativeQueries annotation.

//Stock.java
...
@NamedNativeQueries({
@NamedNativeQuery(
name = "callStockStoreProcedure",
query = "CALL GetStocks(:stockCode)",
resultClass = Stock.class
)
})
@Entity
@Table(name = "stock")
public class Stock implements java.io.Serializable {
...
Call it with getNamedQuery().

Query query = session.getNamedQuery("callStockStoreProcedure")
.setParameter("stockCode", "7277");
List result = query.list();
for(int i=0; i Stock stock = (Stock)result.get(i);
System.out.println(stock.getStockCode());
}
3. sql-query in XML mapping file
Declare your store procedure inside the “sql-query” tag.

Call it with getNamedQuery().

Query query = session.getNamedQuery("callStockStoreProcedure")
.setParameter("stockCode", "7277");
List result = query.list();
for(int i=0; i Stock stock = (Stock)result.get(i);
System.out.println(stock.getStockCode());
}
Conclusion
The above three approaches are doing the same thing, call a store procedure in database. There are not much big different between the three approaches, which method you choose is depend on your personal prefer.
