The following example returns the base type of a synonym's base object that is a remote object located on a server named Server1. SELECT OBJECTPROPERTYEX(OBJECT_ID('MyEmployee'), 'BaseType') AS BaseType The following example returns the base type of a synonym's base object that is a local object. For more information, see OBJECTPROPERTYEX (Transact-SQL). To find the base type of the base object of a synonym, use the OBJECTPROPERTYEX function. For more information, see sp_addextendedproperty (Transact-SQL). Because the property is stored in the database, all applications that read the property can evaluate the object in the same way. For more information, see sys.synonyms (Transact-SQL).īy using extended properties, you can add descriptive or instructional text, input masks, and formatting rules as properties of a synonym. This catalog view exposes synonym metadata such as the name of the synonym and the name of the base object. The sys.synonyms catalog view contains an entry for each synonym in a given database. You can GRANT, DENY, and REVOKE all or any of the following permissions on a synonym:įor more information about schema-bound functions, see Create User-defined Functions (Database Engine). Only synonym owners, members of db_owner, or members of db_ddladmin can grant permission on a synonym.

For more information about how to create synonyms, see CREATE SYNONYM (Transact-SQL). For example, if you own a schema x, but y is your default schema and you use the CREATE SYNONYM statement, you must prefix the name of the synonym with the schema x, instead of naming the synonym by using a single-part name. If you have a default schema that you do not own and want to create a synonym, you must qualify the synonym name with the name of a schema that you do own. These references will only be found at run time. However, by dropping a synonym, you run the risk of leaving dangling references to the synonym that was dropped. Therefore, a synonym can be dropped at any time. References to synonyms are not schema-bound.

If the Contact table is dropped and replaced by a view named Person.Contact, M圜ontacts now references the Person.Contact view.

For example, consider a synonym, M圜ontacts, that references the Person.Contact table in Adventure Works. Therefore, the base object can be modified, dropped, or dropped and replaced by another object that has the same name as the original base object. All existence, type, and permissions checking on the base object is deferred until run time. The binding between a synonym and its base object is by name only. You can create synonyms for the following database objects:įour-part names for function base objects are not supported.Ī synonym cannot be the base object for another synonym, and a synonym cannot reference a user-defined aggregate function. Because there is no ALTER SYNONYM statement, you first have to drop the synonym, EmpTable, and then re-create the synonym with the same name, but point the synonym to the new location of Employee.Ī synonym belongs to a schema, and like other objects in a schema, the name of a synonym must be unique. Also, if the location of the Employee table changes, you will have to modify the synonym, EmpTable, to point to the new location of the Employee table. Now, the client application only has to use the single-part name, EmpTable, to reference the Employee table. To address both these issues, you can create a synonym, EmpTable, on Server2 for the Employee table on Server1. Also, if the location of the table were to change, for example, to another server, the client application would have to be modified to reflect that change. To reference this table from another server, Server2, a client application would have to use the four-part name. Provides a layer of abstraction that protects a client application from changes made to the name or location of the base object.įor example, consider the Employee table of Adventure Works, located on a server named Server1.

Provides an alternative name for another database object, referred to as the base object, that can exist on a local or remote server. A synonym is a database object that serves the following purposes:
