latex escape chars

I want to prepare a text for the use in a LaTeX document.

I wrote a SQL Function which does a lot of REPLACE. For example _ -> \_ and so on.

But there are so many 开发者_高级运维special chars and sometimes I get errors. Does anyone know a SQL-function or a Java package for escaping text to LaTeX?

There are only 10 special chars: \ { } _ ^ # & $ % ~.

Use a verbatim environment or the listings package, then you can enter source code without escaping.
