MyBatis Empty Set Tag: Fix with Default Values

If there is no content inside the tag in MyBatis, you can solve this problem by specifying a default value. For example, you can set a default value within the tag as shown below:

<set>
    column_name = #{propertyName, jdbcType=VARCHAR, javaType=String, mode=IN}
</set>

In this way, even if there is no content inside the tag, the default value will still be set. This helps prevent errors caused by empty tags.
