I have to ask, how can this possible speed anything up? The only reason that comes to mind is the developers don't know how to do a function call on a fixed value, so they want to join through a table? Maybe its really a developer education issue...

Subject: Case for Index Organized table?  

Hi all,    

I got a requirement from the developers to build a new table which has a column that will hold every second of every business day. That is the only column in the table. The table will be truncated everyday and loaded with the subsequent day's time. The developers told me that this table speeds up their queries, I also talked about using other ways but they said that they tested a few ways and found this one the best. They also want an index on that table. I am thinking of creating an index organized table for this purpose. Does anyone foresee any problem in this approach.    

Ram.
