DROP SCHEMA (Transact-SQL)

[!INCLUDEtsql-appliesto-ss2008-all_md]

Removes a schema from the database.

Transact-SQL Syntax Conventions

Syntax

-- Syntax for SQL Server and Azure SQL Database  
  
DROP SCHEMA  [ IF EXISTS ] schema_name  

-- Syntax for Azure SQL Data Warehouse and Parallel Data Warehouse  
  
DROP SCHEMA schema_name  

Arguments

IF EXISTS

Applies to: [!INCLUDEssNoVersion] ([!INCLUDEssSQL15] through current version).

Conditionally drops the schema only if it already exists.

schema_name
Is the name by which the schema is known within the database.

Remarks

The schema that is being dropped must not contain any objects. If the schema contains objects, the DROP statement fails.

Information about schemas is visible in the sys.schemas catalog view.

Caution [!INCLUDEssCautionUserSchema]

Permissions

Requires CONTROL permission on the schema or ALTER ANY SCHEMA permission on the database.

Examples

The following example starts with a single CREATE SCHEMA statement. The statement creates the schema Sprockets that is owned by Krishna and a table Sprockets.NineProngs, and then grants SELECT permission to Anibal and denies SELECT permission to Hung-Fu.

USE AdventureWorks2012;  
GO  
CREATE SCHEMA Sprockets AUTHORIZATION Krishna   
    CREATE TABLE NineProngs (source int, cost int, partnumber int)  
    GRANT SELECT TO Anibal   
    DENY SELECT TO Hung-Fu;  
GO  

The following statements drop the schema. Note that you must first drop the table that is contained by the schema.

DROP TABLE Sprockets.NineProngs;  
DROP SCHEMA Sprockets;  
GO  

Examples: [!INCLUDEssSDWfull] and [!INCLUDEssPDW]

The following example creates the schema Sprockets and a table Sprockets.NineProngs.

-- Uses AdventureWorks  
  
CREATE SCHEMA Sprockets;  
CREATE TABLE NineProngs (source int, cost int, partnumber int);  
GO  

The following statements drop the schema. Note that you must first drop the table that is contained by the schema.

DROP TABLE Sprockets.NineProngs;  
DROP SCHEMA Sprockets;  
GO
