Sql Server trigger insert values from new row into another table

Question

I have a site using the asp net membership schema   I d like to set up a trigger on the aspnet users table that inserted the user id and the user name of the new row into another table     How do I go about getting the values from the last insert    I can select by the last date created but that seems smelly   Is there a better way

You can use OLDand NEW in the trigger to access those values which had changed in that trigger  Mysql Ref

You use an insert trigger - inside the trigger  inserted row items will be exposed as a logical table INSERTED  which has the same column layout as the table the trigger is defined on   Delete triggers have access to a similar logical table called DELETED   Update triggers have access to both an INSERTED table that contains the updated values and a DELETED table that contains the values to be updated

In a SQL Server trigger you have available two psdeuotables called inserted and deleted  These contain the old and new values of the record    So within the trigger  you can look up the create trigger parts easily  you would do something like this   Insert table2  user id  user name  select user id  user name from inserted i left join table2 t on i user id   t userid where t user id is null   When writing triggers remember they act once on the whole batch of information  they do not process row-by-row  So account for multiple row inserts in your code

When you are in the context of a trigger you have access to the logical table INSERTED which contains all the rows that have just been inserted to the table  You can build your insert to the other table based on a select from Inserted
