Which Stored Procedure access my Table?

I have the following strange problem that i can't solve till now:

We have a portal database that contain user table which contain a boolean column called IsAvtive tat determined if the user is active ( can make login to our portal ) or not ..

this column valu开发者_如何学运维e is changed to be False by unknown code .. I search a lot about the source code that change it but i can't find ( we have a lot of old DLL and code that i can't see all) ,we always use stored procedure to update this table ..

I think If is there any way to know the stored procedure that access this table during last 7 days and then I cam trace them ?

Some options

• Add a trigger to the table that logs into another table
• Run SQL Profiler
• Remove write permissions on this column, see who calls

You probably could check into Logs. Take a look into C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA and the database name _log.ldf
