Question

Is there a way i can do multiple inserts into one table using a condition?

i have a list of subscribers in tbl_subscribers. i have an update on productX so i would like everyone who is subscribes to productX to get a notification. The user_notification table is id PK, user_id, notification_id. The two values i need is product_id (productX) which allows me to find a list of subscribers in tbl_subscribers and the notification_id to insert into the user_notification table.

How can i do this insert using one query? I see you can do a select statement in sqlite http://www.sqlite.org/lang_insert.html but i cannot wrap my head around how i may do this nor seen an example.

Answer 1

insert into user_notification(user_id, notification_id)
select s.user_id, @notification_id 
from tbl_subscriber s 
where s.product_id = @productX
