Assume I have a function, as user click a button it will copy last year's data and insert data into this year. How to use SQL statement to fulfill this requirement?
How To
We can use insert with a select subquery to implement this requirement
By using a SELECT subquery to specify the data values for one or more rows, such as:
INSERT INTO dbm031fa(sta_date, age, fund_id, fund_name, age_type, remark, user_id, update_date) SELECT DATEADD(YEAR, 1, sta_date) sta_date, age, fund_id, fund_name, age_type, remark, user_id, CURRENT_TIMESTAMP update_date FROM dbm031fa WHERE year(sta_date) = year(CURRENT_TIMESTAMP)-2
