Postgresql
Postgres SQL:從刪除中插入
我有一張桌子,
id,user_id,timestamp
我正試圖INSERT
進入桌子,user_id
從 aDELETE from table where id=some_number
和timestamp
. 所以我想要實現的看起來像:INSERT INTO table (user_id,timestamp) VALUES ( (DELETE FROM table WHERE id=some_number returning user_id), current_timestamp+'1 day' ) RETURNING *;
執行此操作時出現語法錯誤…有人可以在這裡幫助我嗎…?
您可以使用數據修改公用表表達式:
with deleted as ( DELETE FROM some_table WHERE id = 42 returning user_id ) INSERT INTO other_table(user_id, "timestamp") select user_id, timestamp '2020-01-04 21:32:34' from deleted;
