Question

I just started a new job and was given a bug to track down and fix. The basic issues it that a field in a DB record is being cleared out and no one knows why. So far I have tried:

• Checking the table for triggers,
  there are none.
• Monitoring the table using SQL
  Server profiler for the last couple
  of days in the hopes that the error
  would happen again but unfortunately
  it hasn’t.
• Reviewing all the code that does
  inserts/updates and I didn’t see
  anything that would cause this
  problem.

Does anyone have any other suggests for finding what could have updated this record? Am I not checking something that I should be? Are there any other sources of information that I should look at?

Answer 1

Create a trigger that will write to a history table. Include columns for the date of the write as well as the user.
