DROP SYNONYM (Transact-SQL)

schema

Specifies the schema in which the synonym exists. If schema is not specified, SQL Server uses the default schema of the current user.

synonym_name

Is the name of the synonym to be dropped.

References to synonyms are not schema-bound; therefore, you can drop a synonym at any time. References to dropped synonyms will be found only at run time.

Synonyms can be created, dropped and referenced in dynamic SQL.

To drop a synonym, a user must satisfy at least one of the following conditions. The user must be:

• The current owner of a synonym.

• A grantee holding CONTROL on a synonym.

• A grantee holding ALTER SCHEMA permission on the containing schema.

The following example first creates a synonym, MyProduct, and then drops the synonym.

USE tempdb;
GO
-- Create a synonym for the Product table in AdventureWorks2012.
CREATE SYNONYM MyProduct
FOR AdventureWorks2012.Production.Product;
GO
-- Drop synonym MyProduct.
USE tempdb;
GO
DROP SYNONYM MyProduct;
GO
