Drop Tables
The Database Navigator is able to drop existing tables. Dropping tables means that the table definition (including all data stored in the table) is immediately deleted. There is no way to bring the table or the content back, so be sure to check twice before dropping a table.
Rename Tables
The Database Navigator can issue a rename command on database servers that support table renaming. Table renaming is supported by Oracle, MySQL, PostgreSQL and many other database servers.
Table renaming is not supported by MS SQL Server, OpenBase and Sybase. If you want to rename a table with these database servers you have to create a new table, copy the data and drop the existing table.
