Hi Varshika STUFF function to overwrite existing characters. Using this syntax STUFF(string_expression start length replacement_characters) string_expression is the string that will have characters substituted start is the starting position length is the number of characters in the string that are substituted and replacement_characters are the new characters interjected into the string. REPLACE function to replace existing characters of all occurance. Using this syntax REPLACE(string_expression search_string replacement_string) where every incidence of search_string found in the string_expression will be replaced with replacement_string.
