regex - MongoDB Get distinct formats from a field -


मेरे पास फ़ोन नंबर के विभिन्न प्रकार के फोन नंबर हैं 

  + 9 0 224- XXXXXXX +90 223-XXXXXXX +90 228-XXXXXXX (0221) XXX XXXX (0224) XXX XXXX (0222) XXX XXXX

क्या सभी विशिष्ट फोन प्रारूप प्राप्त करने में mongodb सहायता कर सकता है?

अपेक्षित आउटपुट है: 2

अच्छी तरह से आप इसके लिए उपयोग कर सकते हैं, यद्यपि एक अद्भुत नक्शे में रीडूस जिस तरह से: 

  db.collection.mapReduce (// मैपर - सभी अंकों को "एक्स" फ़ंक्शन के साथ बदलें (emit ("pattern", this.number.replace (new RegExp ("[ 0-9] "," जी ")," एक्स ")}, // रेड्यूसर फ़ंक्शन (कुंजी, मान) {var परिणाम = {आइटम: []}; मूल्य .for (समारोह (मूल्य) {// केवल जोड़ें * नहीं मिला * परिणाम के लिए आइटम (result.items.indexOf (मान) == -1) {result.items.push (मान);}}); वापसी परिणाम;}, // आउटपुट {बाहर: {इनलाइन: 1}});

ऐसा कुछ दे देंगे: 

  {"परिणाम": [{"" _id ":" पैटर्न "," मूल्य ": {" आइटम " : ["+ XX XXX-XXXXXXX", "(XXXX) XXX XXXX"]}}], "समय मीलियाँ": 4, "गणना": {"इनपुट": 3, "emit": 3, "कम करें": 1 , "आउटपुट": 1}, "ओके": 1,}

मुझे लगता है कि यह सिर्फ निरीक्षण के लिए है। लेकिन यदि आप अपडेट करना चाहते हैं या कुछ और उपयोगी हैं तो आप आइटम भाग regex टेम्पलेट्स का निर्माण कर सकते हैं।

c# - Reactive Extensions ControlScheduler -

Well, I'm using Reactive Extension Event Handler to handle my app events, I run the headlines on the Yuri thread. I also use ControlSubular for However, recently I am getting cross thread exception despite using control scheduler and I do not know what the problem is. Code: Observable.FromEventPattern & Lt; String & gt; (CC, "UiAlertMessage", New Control Session ()) Subscribe (_ = & gt; {Alert Control. (Show this language, title, _.EventArgs.UppercaseFirst ());}); The new control scheduler (this) is not to run the code on the UI control thread, so I do not get cross threading exceptions? you should do Observable.FromEventPattern & lt; String & gt; (CC, "UiAlertMessage"). AboveOption (this). Subscribe (_ = & gt; {Alert Control. (Show this language, Titles, _.EventArgs.UppercaseFirst ());}); This is the standard way of sending a scheduler related to specific controls. Passing control scheduler as you have got subsc...
