Question

I have a system where the customer wants to rework the current model so that everytime a user makes a change an administrator must accept the change before its written to the database..

I was thinking of doing a quick fix for this by overriden SaveChanges and taking each object in the ObjectStateManager and adding its intended sql code to a limbo table that would keep the inteded sql query saved until an admin has accepted it (and then run it).

I know that you can use ToTraceString() on database querys, but can you somehow pull the intended sql query on the object taken from ObjectStateManager?

Was thinking something like this:

var modified = DB.ObjectStateManager.GetObjectStateEntries(System.Data.EntityState.Modified);

        foreach (var mod in modified)
        {

            //Insert the query to the limbo table         
            tblPendingChanges change = new tblPendingChanges();

            //Code omitted
            change.sql = mod.Query;
            //Code omitted
            DB.tblPendingChanges.AddObject(change);

            mod.Delete();

        }
DB.SaveChanges();

I solved this issue by using a entity wrapper found here

This allowed me to read each sql statement before it was sent to the server. Redirecting it.

I had to edit the wrapper to allow parameters to be inserted correctly into the statement so that the sql statement could be run.
