Transact-SQL syntax conventions

Syntax

sp_kill_filestream_non_transacted_handles [
    [ @table_name = ] 'table_name'
    , [ [ @handle_id = ] handle_id ]
    ]

Arguments

[ @table_name = ] 'table_name'

The name of the table in which to close nontransactional handles.

You can pass table_name without handle_id to close all open nontransactional handles for the FileTable.

You can pass NULL for the value of table_name to close all open nontransactional handles for all FileTables in the current database. NULL is the default value.

[ @handle_id = ] handle_id

The optional ID of the individual handle to be closed. You can get the handle_id from the sys.dm_filestream_non_transacted_handles dynamic management view. Each ID is unique in a SQL Server instance. If you specify handle_id, then you also have to provide a value for table_name.

You can pass NULL for the value of handle_id to close all open nontransactional handles for the FileTable specified by table_name. NULL is the default value.

Return code values

0 (success) or 1 (failure).

Result set

None.

Remarks

The handle_id required by sp_kill_filestream_non_transacted_handles isn't related to the session_id or unit of work that is used in other kill commands.
