mybatis update

MyBatis is a Java-based persistence framework that provides support for executing SQL statements and mapping the results back to Java objects. To update data in a database using MyBatis, you can use the following steps:

1. Define an update statement in a MyBatis mapper XML file or annotation-based mapper interface.

<update id="updateUser" parameterType="User">
   UPDATE users SET name=#{name}, age=#{age} WHERE id=#{id}
</update>

2. Create a MyBatis SqlSession object.

SqlSession sqlSession = sqlSessionFactory.openSession();

3. Call the update() method of the SqlSession object, passing in the update statement ID and the object to be updated.

User user = new User();
user.setId(1);
user.setName("John");
user.setAge(30);
sqlSession.update("updateUser", user);

4. Call the commit() method of the SqlSession object to commit the transaction.

sqlSession.commit();

5. Close the SqlSession object.

sqlSession.close();

These steps will execute the update statement and update the data in the database.
