SQL Server 2005:charindex starting from the end -

-

I have some string 'file.name', I want to capture some 'file'.

To do this, I need to search for the last event. 'In a string.

My solution is: 

  Declare @someStr varchar (20) Announced @reversedStr varchar (20) Announce @ index int set @someStr = '001.002 003' set @reversedStr = reverse (@someStr) set @ index = lan (@sOSATR) - select the charandx ('.', @ Reversed STR) (@ some ST, @ index)

Well, is not it too complicated? I'm just ready to use some of the files.

Does anybody have a good idea?

What do you need to do with it ?? Do you need to catch the letters after the last chance of a given delimiter?

If this is the case: Reverse the strings and search using the usual CHARINDEX: 

  Announce @test negotiation (100) set @test = 'some.file Name 'declare @ ruchars varchar (100) set @reversed = reverse (@test) select reverse (SUBSTRING (@ in return, CHARINDEX ('. ', @reversed) +1, 100))  < / Pre> 
 You will receive "some.file" back - the previous ".in the original file name. 
 
 You do not have any" LASTCHARINDEX "or something that is not directly in SQL Server. What are you doing in a great net. Extension A The extensions library and it can be applied as an assembly in SQL Server - T-SQL string is not strong enough to manipulate, while NAT is actually.

SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
