A database management system having a dropped table recovery flag. If the dropped table recovery flag is on, at the time that a table is dropped an entry will be made in a dropped table history file. The dropped table history file contains a timestamp of the time of table drop, a unique dropped table identifier, and table definition information. The system includes a command to permit the table space of a dropped table to be restored and rolled forward to the point of the dropped table drop. The restored and rolled forward dropped table data is written to a flat file. The flat file data is loaded into a recreated table in the current table space to recover the dropped table.
