Insert auto increment primary key into foreign key table - mysql

Question

I have 2 tables User and UserLogin. UserLogin have a foreign key relationship with User table. What I want to do here is whenever I insert data into the User table through my API their autogenerated(user_id) auto-inserted into UserLogin table.
User table:
user_id | user_name | user_email
UserLogin table:
user_id | user_password | user_number
So when I run my query to add name and email in User table then autoincremented user_id is automatically inserted in UserLogin table with the provided password and number. How can I achieve this and is that thread safe?

Answer 1

yes it is possible and usually can be optained by ##identity try something like
set nocount off;
insert into User Values("Name","Email")
declare #lastID = ##identity
insert into UserLogin values(#lastID,"Password","number")
