update trigger

Hi,

I want to write one trigger on insert and update. Please find below trigger, it is working in case of insert but it is not working in case of update.

ALTER trigger [dbo].[TR_AIU_People_SearchName] on [dbo].[People] AFTER INSERT, UPDATE
as
begin
      update dbo.People
            set SearchName=(ltrim(rtrim(PrefFirstName)) + ltrim(rtrim(PrefMidName)) + ltrim(rtrim(PrefLastName)) + PrefNameLocal
                                    + ltrim(rtrim(LeglFirstName)) + ltrim(rtrim(LeglMidName)) + ltrim(rtrim(LeglLastName)) + LeglNameLocal
                                    + ltrim(rtrim(PrimFirstName)) + ltrim(rtrim(PrimMidName)) + ltrim(rtrim(PrimLastName)) + PrimNameLocal)
      where PeopleId = PeopleID
end;

I am using sql server 11.0. Please check where PeopleID = PeopleID here what should i give? i tried with SCOPE_Identity() and @@IDENTITY but it is not working.

Thanks,

You have to use the inserted system trigger table in order to make it work:

ALTER trigger [dbo].[TR_AIU_People_SearchName] on [dbo].[People] AFTER INSERT, UPDATE
as 
begin
	update p 
		set SearchName=(ltrim(rtrim(i.PrefFirstName)) + ltrim(rtrim(i.PrefMidName)) + ltrim(rtrim(i.PrefLastName)) + i.PrefNameLocal
						+ ltrim(rtrim(i.LeglFirstName)) + ltrim(rtrim(i.LeglMidName)) + ltrim(rtrim(i.LeglLastName)) + i.LeglNameLocal
						+ ltrim(rtrim(i.PrimFirstName)) + ltrim(rtrim(i.PrimMidName)) + ltrim(rtrim(i.PrimLastName)) + i.PrimNameLocal) 
	from
		dbo.People p
		inner join inserted i
			on i.PeopleId = p.PeopleID 
end;
