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

I had the same problem and made the same response as Tim Biegeleisen, but in a function:

CREATE FUNCTION DBO.FN_REPLACE_FIRST(@X NVARCHAR(MAX), @F NVARCHAR(MAX), @R NVARCHAR(MAX)) RETURNS NVARCHAR(MAX) AS BEGIN
RETURN STUFF(@X, CHARINDEX(@F, @X), LEN(@F), @R)
END

So I just call the function instead:

SELECT DBO.FN_REPLACE_FIRST('Text example', 'ex', 'eexx') --> Returns 'Teexxt example'

The explanation is the same
