Hello,
I need CLR application that will read log files as well as database files(MDF) locked by MS SQL Server. To do it you will need to use duplicatehandle() WIN API and then send it to the client throught either sql pipe or socket piping...
Hint;
1. Locked File Handle can be obtained from "sys.dm_io_virtual_file_stats" system catalog view
2. The application will be Class Library as a SQLFunction registrated on the SQL server as an ASSEMBLY. Since this will be in-process with MS SQL(not kernel mode or out of process app.) obtaining file handle is easy (by using DuplicateHandle() API....)
3. Bear in mind that sometimes this application will read huge files in size, where cursor location needs to be set at the desirable offset and read only small fragment of the file. (MapViewOfFile API will not work!)
Regards,
