मेरे पास एक क्वेरी है जिसे मुझे एक सार्थक कॉलम नाम आउटपुट करने के लिए गतिशील क्वेरी के रूप में चलाने की आवश्यकता है। उदाहरण के तौर पर, यदि मैं सीधे क्वेरी चलाता हूं, तो यह डेटा सही तरीके से देता है। हालांकि, अगर मैं नीचे दिए गए कोड का उपयोग करें, यह पता चलता है:निष्पादन विफल हुआ क्योंकि नाम वैध पहचानकर्ता नहीं है?
DECLARE @query NVARCHAR(4000)
SET @query = N'SELECT *

यह क्योंकि पूर्ण में शामिल होने की है:
The name '

यह नीचे कोड है?
इसके बारे में खेद है। मुझे यह पता लगाने में थोड़ी देर लग गई कि चेक प्रतीक पर क्लिक किया जा सकता है। – urlreader
