MyBatis Update Multiple Tables: Complete Guide
In MyBatis, there are two ways to update multiple tables at once.
- Manually write multiple update statements: You can write multiple update statements in the mapper.xml file to update different tables separately. Then in the Java code, these update statements can be executed one by one by calling the update method of SqlSession.
- Dynamic SQL provided by MyBatis is a powerful feature that allows for the generation of SQL statements based on different conditions. It can be used in the mapper.xml file to create multiple update statements, which can then be executed in Java code by calling the update method of SqlSession.
It is important to note that when updating multiple tables at once, transaction management should be considered to ensure that all updates either succeed or fail together. This can be achieved by using a transaction manager in Java code to manage the transactions of multiple update operations.
