php - SQL field value of 0 returns empty -

-

I have variable types of data in the SQL database, and I am populating the table with PHP.

Sometimes I have 3 columns, sometimes I have more depending on the type of data I use if: 

  $ fourth column = $ Row ['fourth']; If (empty ($ fourth column)) {// nothing} other {resonant "  
 Then it works as expected with a single exception: some columns are quantities when the quantity is '0', then it is returning empty and with the value of '0' TD does not make.  
 In my composition, if there is no information, the cell is completely empty, and that is what I hope to return to empty form  
 What '0' Is there any way to return? What am i doing wrong   
 
 
  blank (0)  evaluates correctly Php  
  
 so that you can clearly check  
  if (empty (fourth column) & amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; fourth column! == 0 & amp; amp;; fourth column! == "0") {// nothing} other {resonant "& lt; td class = 'fourth' & gt; . $ Fourthcolumn "& Lt; / td & gt;"; }

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
