sql - not able to convert String date to unix timestamp in hive -


मैंने निम्न क्वेरी निष्पादित करने की कोशिश की: 

  SELECT L_RETURNFLAG, L_LINESTATUS, SUM (L_QUANTITY ) AS SUM_QTY, SUM (L_EXTENDEDPRICE) के रूप में SUM_BASE_PRICE, SUM (L_EXTENDEDPRICE * (1 - L_DISCOUNT)) SUM_DISC_PRICE के रूप में, SUM (L_EXTENDEDPRICE * (1 - L_DISCOUNT) * (1 + L_TAX)) SUM_CHARGE, AVG (L_QUANTITY) के रूप में AVG_QTY, औसत (L_EXTENDEDPRICE) AVG_PRICE के रूप में, औसत (L_DISCOUNT) एवीजीडीआईएससी के रूप में, LINEITEM जहां से यूनिक्स_टाइमस्टैम्प (एलसीएचआईपीडीटीई, 'य्याय-एमएम-डीडी')> 1000 ग्रुप द्वारा L_RETURNFLAG, L_LINESTATUS ORDER द्वारा L_RETURNFLAG, एल_लिनेस्टास;   
 लेकिन,  
 मुझे त्रुटि मिल रही है:  
  फ़ंक्शन 'unix_timestamp' दिए गए तर्क प्रकारों के साथ नहीं मिल सकता है    
 
 
 तर्क को यूनिक्स_टीमस्टैम्प के अंदर स्ट्रिंग में डालने का प्रयास करें
