Removes a PolyBase external table from a database, but doesn't delete the external data.
Transact-SQL Syntax Conventions
DROP EXTERNAL TABLE { database_name.schema_name.table_name | schema_name.table_name | table_name }
[;]
[ 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.
- Requires ALTER permission on the schema to which the table belongs.
Dropping an external table removes all table-related metadata. It doesn't delete the external data.
DROP EXTERNAL TABLE SalesPerson;
DROP EXTERNAL TABLE dbo.SalesPerson;

DROP EXTERNAL TABLE ProductVendor1; The following example drops the SalesPerson table in the EasternDivision database.
