java - How to use CONCAT_WS() in Hibernate HQL -

-

एकाधिक स्तंभों को एक के रूप में संयोजित करने के लिए, 

  SELECT id, CONCAT_WS (',', Field_1, field_2, field_3, field_4) `तालिका` से सूची;   
 यह क्वेरी SQL में ठीक काम करती है लेकिन यह मुझे HQL में त्रुटि देता है: 
 त्रुटि है  
 (java.lang.IllegalStateException: नोड के लिए कोई डेटा प्रकार: org.hibernate.hql.internal.ast.tree.MethodNode)  
 मेरी मदद कृपया क्या गलत पता लगाने के लिए मैं पता करने के लिए किया था, मेरी मदद करो  
 नीचे HQL में CONCAT_WS () का उपयोग करने के लिए कैसे कैसे मैं अपने HQL क्वेरी लिखा  
  का चयन करें C1._URI, C1.HEALTH_FACILITY, C1.DISTRICT , CONCAT_WS ( ',', C1.BLOCKS_OF_BHUBRI, C1.BLOCKS_OF_GOLAGHAT, C1.BLOCKS_OF_HAILAKANDI) Block_name रूप GapAnalysisWashInHealthFacilitiesCore सी 1 से   
 किसी भी मदद   
 सराहना करेंगे 
 
  CONCAT_WS  मेरे एसक्यूएल के लिए विशिष्ट फ़ंक्शन है HQL एक सामान्य भाषा है और मूल एसक्यूएल फ़ंक्शंस और सिंटैक्स से अवगत नहीं है। यदि आपको वास्तव में फ़ंक्शन की आवश्यकता है, तो आपको स्थानीय SQL के लिए हाइबरनेट के एपीआई का उपयोग करना चाहिए।  
  सत्र सत्र = ...; क्वेरी क्वेरी = session.createSQLQuery ("SELECT id, CONCAT_WS (',', field_1, field_2, field_3, फ़ील्ड_4)` तालिका` से ब्लॉक_नाम;); सूची परिणाम = query.list ();   
 फिर आप  GapAnalysisWashInHealthFacilitiesCore  ऑब्जेक्ट की सूची के रूप में परिणाम प्राप्त करना चाह सकते हैं।
