The DeleteFromDB method deletes a bitmap from the database.

OpenROAD deletes the bitmap specified by the current DBHandle attribute setting.

Because the DeleteFromDB method interacts directly with the database, it either initiates a transaction or becomes part of any open transaction. The work that it does is not permanent until the transaction is committed. By default, you must issue a commit statement explicitly. For more information about transaction management and the DeleteFromDB method, see the Programming Guide.

This method returns ER_OK if successful, or a non-zero database error code if unsuccessful. Descriptions of system constant values and their numeric equivalents are listed in Error Codes.

This method does not destroy the in-memory contents of the bitmap object; it only deletes the version stored in the database at the location specified by the DBHandle attribute.
