Syntax

DROP EXTERNAL TABLE { database_name.schema_name.table_name | schema_name.table_name | table_name }
[;]

Arguments

[ database_name . [schema_name] . | schema_name . ] table_name
The one- to three-part name of the external table to remove. The table name can optionally include the schema, or the database and schema.

Permissions

Requires:

  • ALTER permission on the schema to which the table belongs.

Remarks

Dropping an external table removes all table-related metadata. It doesn't delete the external data.

Examples

DROP EXTERNAL TABLE SalesPerson;  
DROP EXTERNAL TABLE dbo.SalesPerson;  
DROP EXTERNAL TABLE EasternDivision.dbo.SalesPerson;

B. Dropping an external table from the current database

The following example removes the ProductVendor1 table, its data, indexes, and any dependent views from the current database.

DROP EXTERNAL TABLE ProductVendor1;

The following example drops the SalesPerson table in the EasternDivision database.

DROP EXTERNAL TABLE EasternDivision.dbo.SalesPerson;
