Tell me what is the STUFF and how does it differ from the REPLACE function?
Answer:
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.
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.
