sql - SUM(a*b) not working -

-

Wo_parts and part2vendor . I am trying to multiply 2 table column row dots together, i.e. wo_parts is a field called qty and a field in part2vendor Which is called cost . These 2 include wo_parts.pn and part2vendor.pn . I have created a query like this: part2vendor INNER as total_score as wo_parts ON (wo_parts.pn =) 

  $ scoreCostQuery = "SELECT SUM (part2vendor.cost * wo_parts.qty) Part2vendor.pn) WHERE WORKER = $ WORKER ";

But if I add the cost of parts multiplied by the supplied qaantsities, then it adds a different number than what the script is doing. Help .... I'm new to this but if someone can show me in SQL then I can modify it for postgres. Thanks

Without seeing the example data, we have no way to know that you query Why are yoga coming out in a different way when you do mathematics by hand it can be a bad insert, so you are getting more / less records than expected. It is also possible that your calculation is closed. Select an example with the smallest number of associated records & amp; Compare.

My suggestion is to add the query to GROUP BY : 

  SELECT SUM (p.cost * wp.qty) to the total_core from FROM Part2vendor p JOIN wo_parts wp on wp.pn = p.pn where workorder = $ was in workorder group functionality by

FYI: MySQL GROUP BY , while another DB Used - it is a source of many questions "Why does it work in MySQL when it does not work on DB x ...".

To check that your quantities are correct: 

  SELECT wp.qty, pOost to WO_PARTS wp PART2VENDOR p on PPN = Wp.pn where p.workorder = $ workorder

Check that the numbers are correct for a given order.

-
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.
