Question

I have had quite some difficulty trying to make a User Defined Function (UDF) in Java for my MySQL Server. I was hoping I could ask for some help on this subject.

Here is what I have done so far:

I have followed the instructions on a Planet MySQL post but I fear that it may be outdated, as the plugin files do not contain a psm_java.so file which was expected to exist in the tutorial.

I need to implement the Levenshtein distance in Java given two strings so that I can return that value back. I know how to do that part, but I have not been able to do the SQL interaction part.

Any help is MUCH appreciated.

System information:

Mac OS X 10.7.2
MySQL 5.5.16

Answer 1

Why go outside the RDBMS? You can implement the Levenshtein distance in a MySQL UDF pretty easily.
