sql - MySQL: Print counted values -

-

सारणी: 

  + ------------- + | IzvajalecID | + ------------- + | 20 | | 21 | | 21 | | 20 | | 21 | + ------------- +   
 मैं सभी विशिष्ट आईडी की गणना करना और उनके मूल्यों को मुद्रित करना चाहूंगा।  
 उदाहरण के लिए:  
 अद्वितीय आईडी:  2  मान:  20, 21   
 मैंने निम्नलिखित क्वेरी के साथ प्रयास किया। गणना ठीक काम करती है, लेकिन यह केवल एक (प्रथम) मान देता है मैं क्या कर रहा हूं?  
  SELECT COUNT (अलग izvajalecID), s.izvajalecID से (चयन izvajalecID से servis) s;    
 
 
  का चयन करें izvajalecID से servis ग्रुप द्वारा izvajalecID UNION SELECT COUNT (DISTINCT izvajalecID) Servis से   
  
 सेट में अंतिम मान अद्वितीय मानों के COUNT के लिए है आप उन जगहों को भी बदल सकते हैं और यह आपकी पहली इच्छा होगी, जैसे आप चाहते हैं।

php - proc_open Too many open files in long running Symfony Console app -

-
I have created a console app with a SIM console console component. It was going to run for 5 hours but after running 2 hours I have a proc_open (): Many open files in the pipeline error Symfony \ Component \ Console \ Application.php On-line 985. I tried to gc_collect_cycles in my code, but got the same error. Is this a Symphonic Console component bug or should I not run any app for this long time (but I have to)? This problem relates to: Obviously you have many resources in your app It's not a symphony console bug, but it's a PHP bug. You can modify your program by using another programming language to open fewer files.
