विदेशी कुंजियों को शामिल करने के लिए Oracle Sql डेवलपर के साथ DDL जेनरेट करें

क्विक डीडीएल किसी भी प्रकार की प्राथमिकताओं का उपयोग नहीं करता है, यह वह करता है जो हमें उचित लगता है - जो पूरी तरह से व्यक्तिपरक है।

हालाँकि, यदि आप ट्री में किसी ऑब्जेक्ट के लिए SQL पृष्ठ पर जाते हैं, तो प्राथमिकताएँ> डेटाबेस> निर्यात में सेट की गई प्राथमिकताओं के बाद DDL उत्पन्न होगा।

संस्करण 4.2 के लिए, आप वर्कशीट में डीडीएल कमांड का भी उपयोग कर सकते हैं। और आप SET DDL का उपयोग बंद करने के लिए या उस प्रकार के DDL को करने के लिए कर सकते हैं जिसे आप जनरेट करना चाहते हैं।
