He Yongqiang updated HIVE-1266: ------------------------------- Assignee: (was: He Yongqiang) > partitioning pruing should be more intelligent > ---------------------------------------------- > > Key: HIVE-1266 > URL: https://issues.apache.org/jira/browse/HIVE-1266 > Project: Hive > Issue Type: Bug > Components: Query Processor > Reporter: Namit Jain > Attachments: hive-1266.1.patch > > > Copying the mail from Adam: > A badly written query: > select .. from T where partitioning_colmn = 'p1' AND c1 = 100 or c2 = 200 > ...is a command I just foolishly ran: I should have put the disjunction in > parentheses. > But the command actually touched every partition of T without a warning. Is > that a bug? When we force people to state a partition predicate, it seems we > are just looking for it to be referenced in the WHERE or ON clause, when > maybe we should be looking at conjuncts? -- This message is automatically generated by JIRA.
