獲取SQL查詢的結果並將其移動到另一個表

Question

我在玩兩張桌子。

表一具有名為“ person_id”的列。 如果person_id 1發表第二條評論，則person_id顯示兩次，依此類推。

我進行了此查詢，該查詢通過單個person_id返回總評論，例如：

SELECT person_id, COUNT(comment) AS total_comments
FROM comments
GROUP BY person_id
;

上面查詢的返回是：

person_id   total_comments
   3             1
   1             2

如何將上面的total_comments信息移到另一個表中？ 據我所知，這將是什么樣的聯接。 內？ 剩下？

Answer 1

INSERT INTO TABLE2 (PERSON_ID, TOTAL_COMMENTS)
SELECT PERSON_ID, COUNT(COMMENT) AS TOTAL_COMMENTS 
FROM COMMENTS GROUP BY PERSON_ID ;
