DROP EXTERNAL RESOURCE POOL (Transact-SQL)

Deletes a Resource Governor external resource pool used to define resources for external processes.

::: moniker range="=sql-server-2016||>=sql-server-linux-ver15" For [!INCLUDErsql-productname-md] in [!INCLUDEsssql15-md], the external pool governs rterm.exe, BxlServer.exe, and other processes spawned by them. ::: moniker-end

::: moniker range=">=sql-server-2017||>=sql-server-linux-ver15" For [!INCLUDErsql-productnamenew-md], the external pool governs rterm.exe, python.exe, BxlServer.exe, and other processes spawned by them. ::: moniker-end

External resource pools are created by using CREATE EXTERNAL RESOURCE POOL (Transact-SQL) and modified by using ALTER EXTERNAL RESOURCE POOL (Transact-SQL).
