As I just learned (but I am still not 100% sure) in ASE Sybase 12.5.1 (or in an earlier version) there are no normal User Defined Functions (except Java Fucntions). In Oracle, MS SQL Server this is standard.
Is there any workaround for that ? They told me that you can use Store Procedures, but this is not the same. I want to create a user function that I can use in my SQL statements over o column.
