मेरे पास एक सवाल है यदि यह संभव है। 

  तालिका एक तालिका बी --- ---- -------- test1 test4 test2 test5 test3 परिणाम ------------------ test1 test4 test2 test5 test3   < P> एक अस्थायी तालिका की तरह लेकिन दो तालिकाओं से। जब आप इस कॉलम को सामान्य चयन बयान की तरह चुनते हैं तो वे परिणाम के संयोजन कर रहे हैं। लेकिन मैं क्या चाहता हूं कि एक-दूसरे के बारे में भी पता न हो, सिर्फ कॉलम में एक तरफ प्रदर्शन हो। क्या मैं तार्किक रूप से चाहता हूँ 
 
 चयन करें (तालिका से स्तंभ का चयन करें, तालिका खण्ड से चुनें स्तंभ) दोहरी से  
 अग्रिम धन्यवाद   
 
 
 यह मानना ​​संभव है, कि क्रम में निर्दिष्ट करने के लिए प्रत्येक तालिका में आपके पास  id  है एसक्यूएल टेबल अनारडेड सेट्स को प्रदर्शित करता है।  
 यहां एक विधि है, जिसमें ओरेकल सहित अधिकांश डेटाबेस में काम करना चाहिए:  
  कोला के रूप में t1.col1 चुनें, कोला के रूप में t2.col1 (टी 1 पर चयन करें t1। *, Row_number () से (संख्या के अनुसार) तालिका 1 t1 से seqnum के रूप में) t1 पूर्ण बाहरी कनेक्ट (टी 2 पर चयन करें।), Row_number () से (टेबल के अनुसार seqnum के रूप में) तालिका 2 t2 से) t2 पर t2। Seqnum = t2.seqnum;

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...
