How to replace first and last character of column in sql server?

Question

I want remove first and last comma from string.

Expected Result :

Answer 1

Using LEN could backfire because LEN ignores trailing spaces. These could be added because of ANSI_PADDING defaulting to ON. So, you'd need RTRIM.

For completeness, I've added LTRIM too...

REVERSE(SUBSTRING(REVERSE(RTRIM(LTRIM(SUBSTRING(MyCol, 2, 8000)))), 2, 8000))
