SQl Server Expert needed

I have a sql server database and for some time I notice that one field in a specific table lose it's data once in a while. Once data is gone from that field, I repopulate the data using a query. I need to find out why and how data is being deleted from the field or column and fix the problem. Some of the things that I thought: 1) It might be a data issue that somehow database does itself some maintenance. 2) It might be some sql injection that someone remotely remove the data from that column as data connects to websites. 3) Or something else. You might have to do some investigation using triggers or whatever and fix the problem and see why data just get wiped out from one column in one table. ## Deliverables 1) All deliverables will be considered "work made for hire" under U.S. Copyright law.
