Debugger Exception Notification

Project Project1.exe raised exception class EDatabaseError with message 'tblMemory: Cannot perform this operation on an empty dataset'. Process stopped. Use Step or Run to continue.

Note : In the above case I have only 2 records, so the table becomes empty with the second Delete.
