Notes taken from PharmSUG seminar
SOUNDEX (Sound Alike)
Ignore case, embedded blanks and punctuations; works best with English-sounding names;
Example:
WHERE varx = * "Michael";
SPEDIS (Spelling Distance)
Translating a keyword into a query containing the smallest value distance;
Example:
Spedis_Value = SPEDIS (title, "Michael"); (exact match is value 0)
COMPELVE (Levenshtein Edit Distance)
Provides an indication of how close tow strings are;
Example:
COMPLEV (Category, "Drama") as Complev_Number; (exact match is value 0)
COMPGED (Generalized Edit Distance)
Measure of dissimilarity between two strings;
Example:
COMPGED (M.Title, A.Title, 'ILN') as Compged_Score; (lowest score indicates better match)
I: ignore case, L: ignore leading blank; N:ignore quotation mark
