Wrong output due to Index?
We are facing an extremely confusing issue... In core banking system we have created an index and after creation of index we are facing wrong output of SQL command based on the same table.
Users are complaining that they are getting Unwanted data in the output. I mean output contains the data which should not be there and if we drop the index, then output is correct.
Please note that Application is Temenos T24 and Index is created through application and not by the create index command.
I just want to check one thing.... In Oracle Database if an index is corrupt... is it possible that query output contains ALL the REQUIRED data as well as some data which is NOT REQUIRED.
