Do you know what is REPLACE and STUFF function in SQL Server?
Answer:
STUFF: This function is used to replace the part of string with some another string.
Syntax:
STUFF (String1, Position, Length, String2)
String1 - String to be overwritten
Position - Starting Position for overwriting
Length - Length of replacement string
String2- String to overwrite
Example:
SELECT STUFF(‘Arpit',2,2,'mi')
Output: Amit
REPLACE: This function is used to replace all the occurrences of particular string by another string.
Syntax:
REPLACE(String1, String2, String3)
Example:
SELECT REPLACE(‘Arpit Jain’,’i’,’m’)
Output: Arpmt Jamn
If you want to replace the first occurrence of “I”, Replace wouldn't work, because it always replaces ALL occurrences of the string.
