How to convert Sql query with inner join statement to sql query with Where statement(no inner join in statement) -

-

I have accessed the following SQL query code by using Quebec and it has been converted to SQL. Still, I want proof that I did without help, so I want to take all internal condominiums and want to change them with the WHERE statement. How do I work it out? Please explain and answer. Thanks

SQL query:. 

 Select Entertainer.EntertainerID, Entertainer.FirstName, Entertainer.LastName, Booking.CustomerID, Booking.EventDate, BookingDetail.Category, BookingDetail.Duration, Specialty. Specialty Features, Entertainment Feature. Interactive expert (Entertainer Inner Join (Include BookingDetail on Booking Inner Booking BookingID = BookingDetail.BookingID) on Entertainer.InternerID = Booking Dupet.InternerIDID) Inner Joiner (Specialty Inner Joiner Specialty on Specials.pecialistid = Entertainer Specialty. Specialist ID) On Entertainer EntertainmentID = Entertainer Specialty.InternationalWHERE (Entertainer.InternenairID) = [Enter Entertainer ID]));

This is the strange zodiac statement that I have seen till date. Your query has been changed to ANSI-89 syntax: 

  SELECT e.entertainerid, e.firstname, e.lastname, b.customerid, b.eventdate, bd.category, bd.duration , S .specialitydescription, entertainment from e.entertainerspecialitycost e, BookingDetail bd, Booking b, EntertainerSpeciality es, attribute where e.entertainerid = bd.entertainerid and b.bookingid = bd.bookingid and e.entertainerid = es.entertainerid and s Specialityid = Es.specialityid and e.entertainerid = [Enter EntertainerID]

Your original query has been cleared from the syntax here - it should help to see general information:

Selection of <> E.entertainerid, e.firstname, e.lastname, b.customerid, b.eventdate, bd.category, bd.duration, s.specialitydescription, es.entertainerspecialitycost pre-entertainment at e j. bd.entertainerid = e.entertainerid BookingDETAIL Join b.bookingid = bd.bookingid Booking b in bd Join ENTERTAINERSPECIALITY es at es.entertainerid = e.entertainerid Join the specialty s.specialityid = es.specialityid ou e.entertainerid =?

The difference ANSI-088 syntax includes the criteria for joining the WHERE section with the actual filter criteria. To say, ANSI-92: 

  join the entertainment ebook at BOOKINGDETAIL bd.entertainerid = e.entertainerid

... versus ANSI- 89: 

  from Entertainment E, BOOKINGDETAIL BD, ... - Example Where e.entertainerid = bd.entertainerid

The purpose of ANSI-92 syntax The preferred choice for:

  • ANSI-89 has not implemented the left zone syntax in different databases, so the statement is that portable
  • ANSI-92 More Powerful Johns Provided (IE: X is not x.id = y.id and x.col)
  • Separating criteria to connect with actual filter criteria, ANSI-92 is easy to read

c# - How to capture HTTP packet with SharpPcap -

-
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.

jquery - SimpleModal Confirm fails to submit form -

-
I am trying to confirm jQuery to show yes / no confirmation when I submit a form. I had modified (in the last list) to capture and block form submissions. However, it only works with jQuery 1.2.6, a recent upgrade stops 1.3.2, if yes is clicked, then by submitting the form. But I can not understand what is wrong / inconsistent in my code now. Demo (which works in both versions of a simple window.href implementation). $ (document) .ready (function () {$ ('input.delete'). Click (function (e) {e.preventDefault (); var target = $ (e .target); Confirm ("Really delete this event?", Function () {target.click ()});});}); How about something like this? The idea of ​​catching clicks (and fire!) On the submitted event is not click event. $ (document) .ready (function () {$ ('# myForm'). Submit (function () {var f = this; Confirm (" Remove? ", Function () {$ (f). Submit ();}) Return; Return the initial session;}}}}; Hope That this is som
