在Hibernate中通过Oracle Function取得单据号码

今天在使用Hibernate开发项目时,遇到一个Oracle Function的问题.
在项目开发中,所有单据的号码产生都是通过一个Function来产生.在这个Function中有一些DML语法,所以不能使用select fun_...() Into v_ref from dual的方法来取得返回结果.
经查询相关资料,Hibernate要求在执行Procedure和Function时都要返回一个游标,所以变通一下方法,我们增加另外一层Function处理.
新定义一个Function 如下:
Function fun_get_vou_web(....)
RETURN SYS_REFCURSOR
as
v_vou varchar2(20);
st_cursor SYS_REFCURSOR;
BEGIN
v_vou := fun_get_vou(....);
OPEN st_cursor FOR
SELECT v_vou as vouno from dual ;
RETURN st_cursor;
END;
然后在hbm.xml中配置:
{ ? = call fun_get_vou_web(.......) }
最后在java中查询name为getNewAppNo的执行结果即可.

How to integrate Hibernate in SpringBoot project
May 18, 2023 am 09:49 AM
Integrating Hibernate in SpringBoot Project Preface Hibernate is a popular ORM (Object Relational Mapping) framework that can map Java objects to database tables to facilitate persistence operations. In the SpringBoot project, integrating Hibernate can help us perform database operations more easily. This article will introduce how to integrate Hibernate in the SpringBoot project and provide corresponding examples. 1.Introduce dependenciesIntroduce the following dependencies in the pom.xml file: org.springframework.bootspring-boot-starter-data-jpam
Java Errors: Hibernate Errors, How to Handle and Avoid
Jun 25, 2023 am 09:09 AM
Java is an object-oriented programming language that is widely used in the field of software development. Hibernate is a popular Java persistence framework that provides a simple and efficient way to manage the persistence of Java objects. However, Hibernate errors are often encountered during the development process, and these errors may cause the program to terminate abnormally or become unstable. How to handle and avoid Hibernate errors has become a skill that Java developers must master. This article will introduce some common Hib
What are the differences between hibernate and mybatis
Jan 03, 2024 pm 03:35 PM
The differences between hibernate and mybatis: 1. Implementation method; 2. Performance; 3. Comparison of object management; 4. Caching mechanism. Detailed introduction: 1. Implementation method, Hibernate is a complete object/relational mapping solution that maps objects to database tables, while MyBatis requires developers to manually write SQL statements and ResultMap; 2. Performance, Hibernate is possible in terms of development speed Faster than MyBatis because Hibernate simplifies the DAO layer and so on.
What is the mapping method of one-to-many and many-to-many relationships in Java Hibernate
May 27, 2023 pm 05:06 PM
Hibernate's one-to-many and many-to-many Hibernate is an excellent ORM framework that simplifies data access between Java applications and relational databases. In Hibernate, we can use one-to-many and many-to-many relationships to handle complex data models. Hibernate's one-to-many In Hibernate, a one-to-many relationship means that one entity class corresponds to multiple other entity classes. For example, an order can correspond to multiple order items (OrderItem), and a user (User) can correspond to multiple orders (Order). To implement a one-to-many relationship in Hibernate, you need to define a collection attribute in the entity class to store
How to perform bulk insert update operations in Hibernate?
Aug 27, 2023 pm 11:17 PM
In this article, we will see how to perform bulk insert/update in Hibernate. Whenever we execute a sql statement, we do it by making a network call to the database. Now, if we have to insert 10 entries into the database table, then we have to make 10 network calls. Instead, we can optimize network calls by using batch processing. Batch processing allows us to execute a set of SQL statements in a single network call. To understand and implement this, let us define our entity − @EntitypublicclassParent{@Id@GeneratedValue(strategy=GenerationType.AUTO)
Introduction to Hibernate framework in Java language
Jun 10, 2023 am 11:35 AM
Hibernate is an open source ORM framework that binds the data mapping between relational databases and Java programs to each other, making it easier for developers to access data in the database. Using the Hibernate framework can greatly reduce the work of writing SQL statements and improve the development efficiency and reusability of applications. Let's introduce the Hibernate framework from the following aspects. 1. Advantages of the Hibernate framework: object-relational mapping, hiding database access details, making development

Java framework technology stack: Introducing commonly used Java frameworks, such as SpringMVC, Hibernate, MyBatis, etc. With the continuous development of Java, more and more frameworks have been developed to simplify the development process. Among them, SpringMVC, Hibernate, MyBatis, etc. are one of the most commonly used frameworks in Java development. This article will introduce the basic concepts and usage of these frameworks to help readers better understand and apply these frameworks. First, let’s introduce Sp
How does Hibernate second level cache work?
Sep 14, 2023 pm 07:45 PM
Caching helps reduce database network calls when executing queries. Level 1 cache and session linking. It is implemented implicitly. The first level cache exists until the session object exists. Once the session object is terminated/closed, there will be no cached objects. Second level cache works for multiple session objects. It is linked with the session factory. Second level cache objects are available to all sessions using a single session factory. These cache objects will be terminated when a specific session factory is closed. To implement the second level cache we need to add the following dependencies to use the second level cache. <!--https://mvnrepository.com/artifact/net.sf.ehcache/ehcache--><de
