String distance metric - Levenshtein distance Optimized with some efford, still, performance depends heavily on the length of the input. Example: select xx_tools_pkg.levenshtein_dist('Hejsan', 'hejsan'), xx_tools_pkg.levenshtein_dist('kitten', 'sitting') from dual; Returns distances of 1 and 3. Probably you would want to apply upper/lower on the…
