Can I rollback Dynamic SQL in SQL Server / TSQL -

-

Can I run a dynamic SQL in the transaction and roll back using EXEC:

exec (select 'from the table; select from * to tablebie;');

Place this in a transaction and use the @@ error after the Adam statement to rollback.

For example. Code 

  BEGIN transfer execution (select 'from * to table; select * to tableb';); IF @@ ERROR! = 0 ROLAB Returning Returns and ELSC Commit Transaction

If there is a dynamic SQL statement and there is an error in N / 2 then the first 1 ((n / 2) - 1) statement roll back

Questions about the first answer

@@ will not take the error error most likely, which means that it can not be possible error, which means Can there be any transaction?

TRY / CATCH in SQL Server 2005+ Yes I am using SQL Server 2005 but have not tried to catch before using 

  BEGIN Start the transcription (select from 'exec; from the table; select;' tableb; ';); Command Transfer End Catch Rollback Transaction End Cache

Or I should look at some other instances on the net 

  Try BEGIN - Start the block of effort BEGIN transfer - Start Transaction .. exec ('SELECT * FROM TableA; SELECT * FROM TableB;'); Quote Tran - Transaction Success! Finally catch if @@ transcount & gt; 0 rollback tran - error RAISERROR (ERROR_MESSAGE (), ERROR_SEVERITY (), 1) END cache

< P> Yes TXN is related to the current session / connection and the dynamic SQL uses the same reference.

However, @@ will not take the most likely error of error: the situation will immediately be checked after the abusive statement. I use TRY / CATCH, SQL Server 2005 +

EDIT: TRY / CATCH should work fine.

-
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. 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.
