Expected Result :

Answer 1

For removing same character you can use below system function TRIM

Only from 2017

DECLARE @str VARCHAR(MAX) = '[REMOVE THIS CLOSE BRACKET]'

SELECT TRIM('[]' FROM @str)

But for different character removing you need to use SUBSTRING

SELECT SUBSTRING(@str,2,LEN(@str)-2)
