DROP SYNONYM (Transact-SQL)
Removes a synonym from a specified schema.
DROP SYNONYM [ IF EXISTS ] [ schema. ] synonym_name
Applies to: SQL Server ( SQL Server 2016 through current version)
Conditionally drops the synonym only if it already exists.
Specifies the schema in which the synonym exists. If schema is not specified, SQL Server uses the default schema of the current user.
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
