How does MyBatis handle pagination?

MyBatis supports two types of paging: physical paging and logical paging.

  1. Based on physical page segmentation:
  2. In SQL, you can achieve physical pagination using the LIMIT and OFFSET keywords. For example, use SELECT * FROM table LIMIT #{offset}, #{limit}.
  3. When defining methods in the Mapper interface, use the @Param annotation to pass the offset and limit parameters.
  4. Based on logical pagination:
  5. Retrieve all records that meet the criteria in SQL without using the LIMIT and OFFSET keywords, and then handle pagination in the application layer using Java code.
  6. In the Mapper interface, we use the @Param annotation to pass query condition parameters and use Java code in the method to handle pagination.

Typically, a physical based pagination is the more common and efficient way of paging. However, a logical pagination can provide more flexible paging capabilities when dealing with smaller query result sets. The choice of which pagination method to use depends on the specific application requirements and database performance.
