    timesten trigonometric  functions


      We cache oracle 11g2 data in timesten   ( IMDB )


      We can't find any trigonometric functions like  cos(x), sin(x)  or so in timesten.

      Does that means timesten doesn't support trigonometric functions?

      So how we work around this problem then?

          TimesTen does not currently support trigonometric functions. The only workaround is to move this processing logic into application code. Of course, that is not always a good solution...

            Thanks for you answer anyway.

            sin/cos/asin  really make me suffer for three days.

            1. First I wanna use external function call c or java math method , but luckily,  timesten doesn't support it.  (oracle does)

            2. Then I  write my own sin/cos/asin algorithm in user defined function (took a long time to make it happen) , but still luckily, timesten doesn't support call user defined function in sql



            I sincerely hope timesten support trigonometric functions and calling user defined function in sql in the next edition (it's still, should be 12.*  like  the oracle 12c).


            It's a long way since v7.0,  I think it's the time to make user happier. Otherwise people should looking solidb for substitute.
