Synonyms
A synonym is an alternative name for a schema-scoped object. You can use a single-part name to reference a base object by using a synonym instead of using a two-part, three-part, or four-part name to reference the base object. Synonyms provide both data independence and location transparency. Synonyms permit applications to function without modification regardless of which user owns the table or view and regardless of which database holds the table or view. However, synonyms are not a substitute for privileges on database objects. Appropriate privileges must be granted to a user before the user can use the synonym.
New synonyms are created within Create Synonym Wizard. In order to run the wizard you should either
• | select the Object | Create Database Object... main menu item; |
• | select the Synonym icon in the Create Database Object dialog |
or
• | select the Synonyms list or any object from that list in the explorer tree; |
• | select the Create New Synonym... item from the popup menu |
or
• | open the schema in Schema Editor and the Synonyms tab there; |
• | press the Insert key or select the Create New Synonym... item from the popup menu (alternatively, you may use the corresponding link of the Navigation Bar). |
To create a new synonym with the same properties as one of the existing synonyms has:
• | select the Object | Duplicate Database Object... main menu item; |
• | follow the instructions of Duplicate Object Wizard. |
|
Synonyms can be edited within Synonym Editor. In order to run the editor you should either
• | select the synonym for editing in the explorer tree (type the first letters of the synonym name for quick search); |
• | select the Edit Synonym ... item from the popup menu |
or
• | open the schema in Schema Editor and the Synonyms tab there; |
• | select the synonym to edit; |
• | press the Enter key or select the Edit Synonym item from the popup menu (alternatively, you may use the corresponding link of the Navigation Bar). |
You can change the name of the synonym using the Rename Synonym dialog. To open the dialog you should either

• | select the synonym to rename; |
