DBCC dllname (FREE) (Transact-SQL)
Unloads the specified extended stored procedure DLL from memory.
When a valid DLL is specified, DBCC dllname (FREE) returns:
DBCC execution completed. If DBCC printed error messages, contact your system administrator.
When an extended stored procedure is executed, the DLL remains loaded by the instance of Microsoft SQL Server 2005 until the server is shut down. This statement allows for a DLL to be unloaded from memory without shutting down SQL Server. To display the DLL files currently loaded by SQL Server, execute sp_helpextendedproc
The following example assumes that
xp_sample is implemented as Xp_sample.dll and has been executed. DBCC dllname (FREE) unloads the Xp_sample.dll file associated with the
xp_sample extended procedure.
DBCC xp_sample (FREE);
