Copy row and all of its 'children'

Question

I have a MySQL table called employees. There\'s another table called shifts that is tied to employees by the employeeId colum

Answer 1

If you want to do this many times, or want to do it on a bulk level, create an sp that inserts a dupe entry for an employee and then inserts dupe entries for all his shifts.

Something like:

CREATE PROCEDURE sp_cloneEmployee
@employeeId int
AS
INSERT INTO employees
SELECT * FROM employees
WHERE employeeId = @employeeId;

INSERT INTO shifts
SELECT * FROM shifts 
WHERE employeeId = @employeeId;
