UDF Introduction   All applications created with m-Power employ SQL to access the database. SQL, by itself, is a very powerful language. A database User Defined Function (UDF) allows users to extend the power of SQL. UDF’s are a powerful yet simple way to perform routine data transformations, calculations, and complex SQL logic. Database vendors Read the rest of this document »

Create and Register a User Defined Function (UDF)   A user defined function (UDF) allows users to extend the power of SQL. Like built-in database functions, UDFs are invoked from SQL statements. They can be a powerful yet simple way to perform routine data transformations, calculations, and complex SQL logic. Database vendors have specific requirements Read the rest of this document »

Function specifications are described below. UDF Name Description Read the rest of this document »

Sample User-Defined Function (UDF) Code   Every database has its own rules for languages which may be used to write User Defined Functions (UDFs). Here are two examples, one written in SQL and another in RPG, showing how to create functions for DB2/400. Example 1: Writing a UDF with SQL We are going to build Read the rest of this document »
