Using Class Method in a Select Where Clause

Hi All,

I have noted something that can be done when processing internal tables but doesn't seem to work for Select statements against a DB table.

So, lets say I have class ZCL_MyClass which has a static method GET_RANGE.

The static method returns a Range.

If I have an internal (lt_tab) I can do the following:

   delete lt_tab where statu in ZCL_MyClass=>GET_RANGE( ).

Is it possible to do something similar when using SQL. for example something like:

   select *
   into table lt_tab

   from mara
   where  statu in  ZCL_MyClass=>GET_RANGE( ).

I have a number of ways I would also like to use this scenario (basically using the class method like a function is used in other languages) but this scenario is specifically what I am interested in at the moment.

I was also wondering whether (if the scenario is possible) whether a singleton would be a good idea in this case?

I have searched the forums but nothing similar seemes to come up.

Look forward to hearing the replies

Many thanks
