My statement did however relate to pre IUS engines. Someone said the UPPER funtion would be included in the normal DS engines. My statement was only that Informix had been told that to include the UPPER (and/or lower) function in that engine would not be too helpfull if it wasn't also possible to create indexes on the function. In IUS that is of course no problem, as it is also no problem to create indexes on any other function, including those you have written yourself. Someone did by the way say that the upper/lower (and other) functions that can be used in Oracle for searches could not be used for indexing. Prety bad implementation if you ask me. Actually next to useless. But what can you expect. My point is that Informix at least know about the problem, have a solution in IUS, and we will have to wait and see what they do in the next version of 7.x.
