Where will you find a functions library?

A functions library can typically be found in programming languages or software development environments. These libraries contain pre-written functions that can be used by developers to perform common tasks or operations without having to write the code from scratch. These libraries are often included with the programming language or development environment, or can be downloaded and installed separately.

In SQL, a user-defined function (UDF) is a function that is defined and created by the user. UDFs are found in the following system metadata tables:

- `AWS_SYS.UDFS`
- `AWS_SYS.UDFS_ARGUMENTS`
