----------------------------------
Summary: Error in semantic analysis:Invalid Table Alias
Key: HIVE-3233
URL: https://issues.apache.org/jira/browse/HIVE-3233
Project: Hive
Issue Type: Bug
Reporter: Raihan Jamal
Priority: Minor
When I am trying to do this query I always get Semantic Analysis error-
hive> SELECT COUNT(*) FROM DW_CHECKOUT_TRANS JOIN PDS_ATTRIBUTE_DATA_REALTIME
ON (DW_CHECKOUT_TRANS.BUYER_ID = PDS_ATTRIBUTE_DATA_REALTIME.UID);
FAILED: Error in semantic analysis: line 1:76 Invalid Table Alias
DW_CHECKOUT_TRANS
But when I add table alias name infront of Table then it starts working? why is
it so? Below query works fine.
SELECT COUNT(*) FROM DW_CHECKOUT_TRANS CO JOIN PDS_ATTRIBUTE_DATA_REALTIME PDS
ON (CO.BUYER_ID = PDS.UID);
