Hi everyone!
I'm working on the n'th application locating zip's. Everything works fine in PHP while I worked along the docu on OpenGeoDB. Now, I'm trying the implementation on the iPhone-SDK, but SQLite doesn't have the ACOS, SIN etc funcs. Can anybody point me to an example of how to expand the SQLite with userfunctions in order to use them in a select?
Any hints appreciated!
Thanx and happy coding! Marcus
