To learn about adding columns, constraints, indexes to the table and defining other table parameters, see Defining Table Structure.

Dropping a Table

Drop a table by selecting Delete on the node shortcut menu.

Note

When you drop a table all data containing in it is lost.

Editing a Table

Editing a table implies editing its structure: changing, removing, or adding columns, indexes, modifying table options. Table editor allows performing all these actions and viewing changes in the script of the table.

To edit a table and view changes:

  1. Right-click it in Database Explorer.
  2. Select Edit Table on the shortcut menu.
  3. Make necessary changes in table structure. See topic Defining Table Structure for detailed information.

  4. Click the Script Changes button to view changes.

    Note

    If you modify column names, a message asking if refactoring should be used, will appear.

  5. To apply changes, click Update Database. If you want to undo all actions made since table document (or any another object editor) was opened or saved, click the Undo button on the Standard toolbar. However, you cannot issue a Redo command for database objects, because when you click Undo, the database object is reloaded from server, and all unsaved changes are lost.
