acazsouza / Levenshtein.sql

Created June 23, 2016 14:22

	-- =============================================
	-- Computes and returns the Levenshtein edit distance between two strings, i.e. the
	-- number of insertion, deletion, and sustitution edits required to transform one
	-- string to the other, or NULL if @max is exceeded. Comparisons use the case-
	-- sensitivity configured in SQL Server (case-insensitive by default).
	-- http://blog.softwx.net/2014/12/optimizing-levenshtein-algorithm-in-tsql.html
	--
	-- Based on Sten Hjelmqvist's "Fast, memory efficient" algorithm, described
	-- at http://www.codeproject.com/Articles/13525/Fast-memory-efficient-Levenshtein-algorithm,
	-- with some additional optimizations.
