是否有列出 SQL Server 中所有内置函数的系统表或系统视图？

Question

I am building an application with which users can create their own user-defined functions in a SQL Server database. I have to validate in some way that the function name picked by the user does not equal to the name of a built-in function (such as avg, concat, ...) since this would break the application.

Is there a way to query the names of all built-in functions (not the UDFs), such as a system view or any the like?

I think it is YOUR rule of naming functions, as long as YOU are the developer. Which means your functions will have always your prefix in database, as mf_ which could mean m y f unction_ and your user's function name. In your code always put that mf_ prefix in front of your user's function call, check if it exists and use it.
