Drops the selected table. See Also: "Using the Recycle Bin to View and Restore Dropped Objects" |
Removes all rows from the selected table. Truncating a table can be more efficient than dropping and re-creating a table. Dropping and re-creating a table may invalidate dependent objects, requiring you to regrant object privileges or re-create indexes, integrity constraints, and triggers. |
|
Creates a lookup table based on the column you select. That column becomes a foreign key to the lookup table. |
