In SQLITE there is a possibility to relatively easily create User-Defined Functions and Aggregates in (extension) languages such as C, Perl, Python and others. Is there also such possibility using common-lisp as SQLITE language extension? I know there are libraries like cl-sqlite and plain-odbc but they don't seem to offer this possibility.
在SQLITE中，可以相对容易地在（扩展）语言（如C，Perl，Python等）中创建用户定义的函数和聚合。是否还有使用common-lisp作为SQLITE语言扩展的可能性？我知道有像cl-sqlite和plain-odbc这样的库，但它们似乎没有提供这种可能性。

When I wrote cl-sqlite, I hadn't thought about user-defined functions.
当我写cl-sqlite时，我没有想过用户定义的函数。
But it's actually pretty easy. It just takes to define callbacks, foreign functions and wrap them in lispy interface. I guess I'll add this feature to cl-sqlite soon.
但它实际上非常简单。它只需要定义回调，外部函数并将它们包装在lispy接口中。我想我很快就会把这个功能添加到cl-sqlite中。
