SQL Server trigger insert values from new row into another table with many-to-many relationship

问题

I have three tables:

• tbl_profiles
• tbl_options
• tbl_profileOption

with many-to-many relationship

what the insert trigger on tbl_options I have to use to add the new options to each profile on tbl_profiles, by default value of isChoose is 0

and on the opposite side when insert a new profile binding it with all options on tbl_options

In other words :

If I add new Option (4....E) to tbl_option, the trigger must be insert two new rows on tbl_profileOption:

1....4.......0
2....4.......0

I hope that my question is clear,

thank for all who try to help me... I got the solution

• first trigger on tbl_option

  go
  Create TRIGGER insertProfileToOption
  ON dbo.tbl_options
  AFTER INSERT
  AS
  insert into tbl_profileOption (profileOption_profileId,
    profileOption_optoinId)
  (select tbl_profiles.profile_id, @@IDENTITY from tbl_profiles)
  

• second trigger on tbl_profile

  go
  Create TRIGGER insertOptionToProfile
  ON dbo.tbl_profiles
  AFTER INSERT
  AS
  insert into tbl_profileOption (profileOption_profileId,
    profileOption_optoinId)
  (select @@IDENTITY, tbl_options.option_id from tbl_options)
  

if there is another solution this will be good, thank you
