SQL सर्वर में सफाई टेलीफोन नंबर

अंतरराष्ट्रीय या यूके आधारित टेलीफोन नंबर स्ट्रिंग की जांच और सफाई के लिए एक SQL सर्वर फ़ंक्शन बनाएं

संदर्भ

क्लाइंट इन्फ्रास्ट्रक्चर पर हमारे सामने सबसे आम चुनौतियों में से एक खराब स्वरूपित टेलीफोन नंबर है। जब वे एक्सेल या आउटपुट को बदलने वाले विभिन्न अन्य परिदृश्यों के माध्यम से चलाए जाते हैं तो वे खराब स्थिति में आ जाते हैं।

यह फ़ंक्शन यूके के नंबरों पर लक्षित है, जिसमें अंतरराष्ट्रीय नंबरों की लंबाई के लिए कुछ गुंजाइश है। पिछले केस स्टेटमेंट में पहले 6 केस आइटम और दूसरे आखिरी केस स्टेटमेंट में तीन केस आइटम को अनुकूलित करके इसे किसी भी अन्य क्षेत्र के लिए आसानी से अनुकूलित किया जा सकता है।

यह कई वर्षों से उपयोग में है, और निम्नलिखित चरणों का उपयोग करके अनगिनत टेलीफोन नंबरों को बचाया है;

एक अस्थायी चर में संख्या का बैकअप लें
आरंभिक चिह्न को दोहरे शून्य से बदलें
स्ट्रिंग से किसी भी शेष टेक्स्ट वर्ण को हटा दें
यूके डायल-इन नंबरों को 0 . से बदलें
प्रत्येक संख्या प्रकार की लंबाई की जाँच करें।
नया नंबर लौटाएं या पुराने नंबर को वापस कर दें यदि यह सत्यापित नहीं किया जा सका।
