उदाहरण।
मेरे पास दो टेबल हैं 

  कार आईडी का नाम 1 बीएमडब्ल्यू 2 फ़ैट Car_info कार_आईडी फ़ील्ड_नाम देश 1 वर्ष 2000 1 देश जर्मनी 2 वर्ष 1988 2 देश इटली   
 एक चुनिंदा क्वेरी में मुझे यह कैसे प्राप्त हो सकता है?  
  id name year देश 1 बीएमडब्ल्यू 2000 जर्मनी 2 फ़ैट 1988 इटली [/ code>   
 
 
 आदर्श रूप में, आपको कॉलम होना चाहिए Car_info तालिका निर्दिष्ट करती है कि उस पंक्ति पर किस प्रकार की जानकारी प्रदर्शित की जा रही है यानी टाइप 1 वर्ष है, प्रकार 2 देश है।  
 आप दो बार 'एएनडीओ' की मेजबानी में शामिल होने से दो बार 'एएनडीओ टेबल' में शामिल होकर गोल कर सकते हैं, जैसे:  <प्री>  का चयन करें car.ID, car.Name, ci1.country [YEAR] के रूप में, ci2.country के रूप में देश से कार इनर में car_info के रूप में ci1 कार पर car.ID = ci1.car_id और ci1.field_name = 'वर्ष 'INNER कार_इन्फो के रूप में सीआई 2 पर कार। आईडी = सीआई 2 सीआर_आईडी और सीआई 2.फील्ड_नाम =' देश '

I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge.
