ऑरैकल में क्वेरी के बाहर आईडी से मेल खाने वाले स्थान का चयन करने के लिए तालिका सेट कॉलम को अपडेट करें

जब आप अद्यतन के साथ उपयोग करते हैं तो आपको अद्यतन तालिका के लिए उपनाम का उपयोग करने की आवश्यकता होती है। यदि नहीं, तो यह काम नहीं करता है।

साथ ही, आप अद्यतन तालिका को विद क्लॉज में नहीं बुला सकते हैं, उस समय वह तालिका अज्ञात है, यही कारण है कि आपको अमान्य पहचानकर्ता मिलता है। समस्या को हल करने के लिए आपको उस शर्त को हटाना होगा और अंत में जोड़ना होगा।

इसे आज़माएं, लेकिन मैं डेटा मॉडल को जाने बिना भी लिख रहा हूं, इसलिए जागरूक रहें।
