Why

Below is my old query sql. and i used it in spring boot jpa environment:

@Query(value = "select key_type,max(key_id) from myzc_string_record group by key_type")
 Map selectMaxKeyTypeAndId();

How
Below is my new query sql,add nativeQuery = true:

@Query(value = "select key_type,max(key_id) from myzc_string_record group by key_type", nativeQuery = true)
 Map selectMaxKeyTypeAndId();

Last
Thanks!
