php - How to get the most recent article date for each category -

-

मेरे पास एक लेख तालिका और एक श्रेणियां सारणी है: <पूर्व> लेख --------------------------------------- -------- | आईडी | दिन-समय | शीर्षक | श्रेणीगत | स्थिति | ----------------------------------------------- श्रेणियाँ -- ----------- | आईडी | नाम | -------------

मुझे चुनने में प्रत्येक श्रेणी से नवीनतम आलेखों की तिथि प्राप्त करने की आवश्यकता है, जैसे: 

 < कोड> परिणाम ----------------------------------------------- ----------- | श्रेणी आईडी | श्रेणी का नाम | हालिया लेख की तारीख | --------------------------------------------------  
 इसका परिणाम होना चाहिए बिल्कुल  श्रेणियों से चयन करें  PLUS एक नया पंक्ति  दिनचर्या  वर्ग के सबसे हाल के लेख के  लेकिन केवल अगर लेख स्थिति 0  है, तो दिखा रहा है। ।  
 क्या यह स्पष्ट है?  
 इसका कारण मुझे इसकी आवश्यकता है क्योंकि मैं एक गतिशील साइटमैप बनाने की कोशिश कर रहा हूं और मुझे नवीनतम श्रेणी के समय को प्रत्येक श्रेणी में दिखाने की आवश्यकता है श्रेणियों की सूची के लिए  और lt; lastmod & gt;  टैग।  
  $ sql = mysql_query ("..... ......... ......"); जबकि ($ string = mysql_fetch_array ($ sql)) {? & Gt; & LT; यूआरएल & gt; & Lt; loc & gt; http: //www.url.com/< ;? echo $ string ['id'];? & Gt; / & lt;? गूंज उत्पन्न_seo_link ($ string ['name']);? & Gt; / & lt ; / loc & gt; & LT; प्राथमिकता & gt; 0.5 & lt; / प्राथमिकता & gt; & LT; changefreq & gt; दैनिक & lt; / changefreq & gt; & LT; lastmod & gt; & lt ;? गूंज तिथि ("डी / एम / वाई एच: आई: एस", स्ट्रैटोमेट ($ स्ट्रिंग ['तारीख'])); ? & Gt; & lt; / lastmod & gt; & Lt; / यूआरएल & gt;     
 
 
  UPDATE2   को समायोजित करने के लिए स्थिति   
  का चयन करें c.id, c.name, MAX (a.datetime) articles from most_recent में एक सही शामिल श्रेणियां c । Categorid = c.id WHERE a.status है नल या a.status = 0 ग्रुप द्वारा c.id, c.name   
 आउटपुट  
  | आईडी | NAME | RECENT_DT | ------------------------------- | 1 | श्रेणी 1 | 2013-03-19 | | 2 | श्रेणी 2 | 2013-03-17 | | 3 | श्रेणी 3 | (नल) |   
 यहां

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee.

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.
