SQL provides a set of useful functions, but they might not satisfy all of the particular requirements you have to process your data.

User-defined functions (UDFs) allow you to extend SQL by writing your own functions in the Java programming language, installing them on the database, and then using them like standard SQL functions.

For details on writing your own functions in the C or C++ programming language, see C/C++ User-Defined Functions.
