I have a query that does not execute empty fields with'% ', but it was not sure how the query was conditional to them Have to end.

  1. Ensure that you have the proper index on the database to support your query Got it Get the database to dump out of the access plan and find out whether tables are accessing tables using a full table scan, if you are using Oracle or any other database that supports the NVL function You can re-write it

  2. / P>

. 

  @Parameter = table.Fieldname OR @Parameter IS Null

as 

  NVL (@Parameter, Table.Fieldname) = table.Fieldname

I have found that it can dramatically improve performance because the second build is likely to be more likely to use an index while The first time is often scanned in the full table.

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is.

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.
