> You can write stored procs in C#.

It just occurred to me that Rust might be a really good fit for user defined functions in MySQL. I would never want to write in C or C++ myself, but with a nice crate that abstracts away and/or provides most the structures you might need to pass back and forth, I would be much more confident that if I got it compiling in Rust that it probably wouldn't blow up my database.

I mean, I think that's one of the major benefits of using C# over C or C++. You're not likely to segfault or buffer overflow, etc.

Is there a database where you can write stored procedures in C or C++? Usually such languages can't segfault or buffer overflow.

User defined functions[1] in MySQL are dynamic libraries which are loaded and then you attach a function name to. A common example might be a hashing function that you want the DB to understand.[2]

That said, I bet just about every database supports something similar (and postgres' equivalent has already been provided by a sibling comment).

Most of them. SQL-like languages like Oracle's PL/SQL are preferred, not because of any security problems but simply because it's much easier, specially when working with data sets.
