With these triggers, now I don't have an excuse any more. However, as I am executing this statement, it is most certainly not January 1st, nor January 1st, So this is exactly what we were looking for. For this example, I am going to use a table that captures restaurant information. And I feel this is an equally important aspect to solve. For this audit trail to be effective, we need to make sure that these columns always contain the correct values. This solves half of the problem, in that a developer no longer has to worry about providing a value. The LastModifiedDate column reflects the last time the row was changed. So first of all, lets define our target table. So even though these columns accept NULL values, we'll take care of that in the triggers that follow. And for the third statement when incorrect values were supplied, these values were not used but again, we have the correct values in these two columns. This is exactly the type of situation we are designing for, to make sure we always have correct values in these columns and not allow them to be overridden by user supplied values like this that may potentially be incorrect. I am not able to give away many details beyond saying I was involved in researching some issues, but what I can say is that two of the questions that always come up are "when did this row come into existence? So I think it is good to blog about how to do this, so if anyone else has this need, they can see my approach and either use it straight away or adapt it to their needs. The CreatedDate record was left unchanged, as were the records for the other rows in the table. This is for two reasons: Lately, I've been involved in researching a number of security related items. Having audit columns that you know are correct and you know cannot be tampered with is critical when researching these sorts of issues. However, with our trigger, we don't allow this to happen and we just retain the existing value. What this does is keeps someone from updating the value of CreatedDate. Using the database value, we know the value is correct and consistent. This is exactly what we want. At the same time though, we want to prevent these columns from being changed, whether maliciously or accidentally so we are confident the values in these columns are always correct. We don't want to burden a developer or someone writing a SQL statement to worry about how to populate these columns, because we can do that automatically. We don't want to rely on user supplied values for these columns. So basically what this does is get the set of affected rows, and go back to the table and update the times to the times that we want.

  3. We want to populate both of these columns automatically from the current database time. So here is the table.
