Replace first occurrence of substring in a string in SQL

Question

I have to fetch data from a @temp table which has something like \"or ccc or bbb or aaa\" I want to replace the first occurrence into space to get something like this \" ccc

Answer 1

it seems you miss 2% preceding and trailing to the target string

please try:

select STUFF(@stringhere, PATINDEX('%' + @stringtofind + '%', @stringhere), LEN(@stringtofind), ' ')
