I have inherited a project that uses LLBLGen Pro for the DB layer. The DB model requires that when a entry is deleted a flag (DeletedDate is set to the current time). The last programmer ignored this requirement and has used regular deletes throughout the entire application.
Is there a way to set the code generator to do this automatically or do I have to overload each delete operator for the Entities that requires it?
I implemented this in SQL Server 2005 using INSTEAD OF triggers on delete for any soft delete table. The triggers set the delete flag and perform clean-up. The beauty of this solution is that it correctly handles deletes issued by any system that accesses the database. INSTEAD OF is relatively new in SQL Server, I know there’s an Oracle equivalent.
This solution also plays nicely with our O/R mapper — I created views that filter out soft deleted records and mapped those. The views are also used for all reporting.
