sql - Alter script not working on server -

-

मेरे पास nvarchar से float डेटाटाइप बदलने के लिए एक लिपि स्क्रिप्ट है जो मेरी स्थानीय मशीन में ठीक काम करता है लेकिन 2012 सर्वर पर काम करने में विफल रहता है

क्या कोई मुझे बता सकता है कि मेरी लिपि में क्या गड़बड़ है या सर्वर पर किसी भी परिवर्तन की आवश्यकता है?

मेरे परिवर्तन स्क्रिप्ट निम्नानुसार है: 

  ALTER TABLE mytable ALTER COLUMN mycolumn FLOAT   
 और मुझे यह त्रुटि मिलती है:  <ब्लॉक> 
 संदेश 8114, स्तर 16, राज्य 5, रेखा 6 
 डेटाटाइप nvarchar को फ्लोट करने में त्रुटि    
 
 
 यदि यह एक त्रुटि फेंक रहा है 'डेटा प्रकार varchar to float में कनवर्ट करने में त्रुटि।' तो यह स्पष्ट है कि varchar क्षेत्र में कुछ मान हैं जो फ्लोट में परिवर्तित नहीं किए जा सकते हैं। यदि आप हमें बताए गए त्रुटि के बारे में अधिक बता सकते हैं, तो समस्या को समझना आसान होगा।

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...
