Bipul tiwari · Answer

The STUFF function inserts a string into another string. It deletes a specified length of characters in the first string at the start position and then inserts the second string into the first string at the start position.

HI STUFF function is used to insert a string into another string by deleting some characters specified. The function below inserts the string nny at the 2nd position and replaces a total of 3 characters. Example: SELECT STUFF('john' 2 3 'nny') Output: jnny On the other hand REPLACE instead of replacing specific characters replaces existing characters of all occurrences. Example: SELECT REPLACE ('Johnnohneny''ohn''ccc'); Output: Jcccnccceny

Hi Both STUFF and REPLACE are used to replace characters in a string. select replace('abcdef''ab''xx') results in xxcdef select replace('defdefdef''def''abc') results in abcabcabc We cannot replace a specific occurrence of def using REPLACE. select stuff('defdefdef'4 3'abc') results in defabcdef where 4 is the character to begin replace from and 3 is the number of characters to replace.
