| We have a field in our table called LUser.This is suposed to be updated by the calling application but not always.Is it possible to add a trigger to update this with the login name?How would I get the login name? |

| Yup. You can do it. You can use SUSER_SNAME() funtion or SYSTEM_USER function to achieve this. I would suggest you to create a DEFAULT constraint on column to ppopulate this value rather than a trigger as performance using trigger will be really slow. |

| but the constraint will only work when inserting won't it?Whereas a trigger everytime it is updated/deleted/inserted. |
