MyBatis provides a feature called "for update" which allows you to lock the selected rows in a database table while performing an update operation. This is useful in scenarios where you want to ensure exclusive access to the selected rows during the update process.
To use "for update" in MyBatis, you can add the "FOR UPDATE" clause to your SQL statement. Here's an example:
```xml
<update id="updateRecord" parameterType="YourParameterType">
UPDATE your_table
SET column1 = #{value1}, column2 = #{value2}
WHERE condition_column = #{conditionValue}
FOR UPDATE
</update>
```
In this example, the `FOR UPDATE` clause is added to the end of the SQL statement. You can customize the SQL statement according to your specific requirements.
Note that the behavior of "for update" may vary depending on the database you are using, as different databases have different locking mechanisms. It is recommended to refer to your database documentation to understand how the "for update" feature works in your specific database.
