Hi All, I have a very big table t with billions of rows and it is partitioned on a column p. Column p has datatype text and values like '201601', '201602'...upto '201612'. And, I am running a query like : Select columns from t where p='201604'.
My question is : Can there be a scenario/condition/probability that my query will do a complete table scan on t instead of only reading data for specified partition key. If yes, please put some light on those scenario. I'm asking this because someone told me that there is a probability that the query will ignore the partitioning and do a complete table scan to fetch output. Thanks & Regards, Abhishek Dubey
