SQL Server Trigger on INSERT always ROLLED BACK -


i want create trigger not allow past client out usa.

so code is:

create trigger location_tr  on t1 insert, update begin     declare @country varchar(50)      set @country = (select country inserted);      if @country <> 'usa'     begin         print 'you cant add user out of usa!'          rollback transaction     end     else         commit transaction end

so now, can't update or insert on table t1.

i guess i'm going wrong commit/rollback commands. need help. thanks

the first issue trigger not support multiple rows. should use exists instead of setting value of variable. along these lines.

create trigger location_tr on t1 insert, update begin     if exists(select * inserted country <> 'usa')         begin             print 'you cant add user out of usa!'             rollback transaction         end     end
