SQLite

The SQLite connector has the Levenshtein function! A couple of examples:

SELECT LEVENSHTEIN( 'Microsoft', 'Technology Advisors, Inc.' )

Result: 21

SELECT LEVENSHTEIN( 'Technology Advisors Inc', 'Technology Advisors, Inc.' )
</source
Result: 2
<source lang="mysql">
SELECT LEVENSHTEIN( 'Bob', 'Tom' )

Result: 2
