STUFF Function: This function is used to overwrite existing character or inserts a string into another string. Syntax:

STUFF(string_expression,start, length, replacement_characters)

where,

  • string_expression: it is the string that will have characters substituted
  • start: This refers to the starting position
  • length: It refers to the number of characters in the string which are substituted.
  • replacement_string: They are the new characters which are injected in the string.

REPLACE function: This function is used to replace the existing characters of all the occurrences. 

Syntax:

REPLACE (string_expression, search_string, replacement_string)

Here every search_string in the string_expression will be replaced with the replacement_string.
