MyBatis query result in a HashMap?
提问by V R
For the below query,
对于以下查询，
SELECT
MSGS.MSGTYPE,
count(*) as NOOFRECORDS
FROM
SCHEMA.MESSAGES MSGS
GROUP BY
MSGS.MSGTYPE
What would be the equivalent in MyBatis mapper so that I can get a Result as a HashMap with MSGS.MSGTYPE as the key and NOOFRECORDS as the value ?
MyBatis 映射器中的等价物是什么，以便我可以将 Result 作为 HashMap 以 MSGS.MSGTYPE 作为键和 NOOFRECORDS 作为值？
采纳答案by V R
<select id="selectAllCategories" resultType="hashmap">
select id, name from categories
</select>
