mybatis FIND_IN_SET

MyBatis is a popular Java-based persistence framework that provides an object-relational mapping (ORM) solution. It simplifies database interactions by eliminating the need for writing raw SQL queries manually.

Regarding your question about `FIND_IN_SET`, it is a MySQL function that searches for a value within a comma-separated list. However, MyBatis does not have direct support for `FIND_IN_SET` as it focuses on providing a simple and intuitive mapping between Java objects and database tables.

To use `FIND_IN_SET` with MyBatis, you can write a custom query using the `<script>` tag within the XML mapper file. Here's an example:

<select id="findInSetExample" parameterType="String" resultType="YourResultType">
  SELECT * FROM your_table
  WHERE
    <if test="yourValue != null">
      FIND_IN_SET(#{yourValue}, your_column) > 0
    </if>
</select>

In this example, `your_table` is the name of the table you want to query, `yourValue` is the value you are looking for, and `your_column` is the column containing the comma-separated list. Adjust these placeholders according to your specific use case.

Remember to include the necessary MyBatis configuration and mappers to enable the execution of this query.
