I was looking for a list of special characters that must be escaped in ms sql server but could not find one and most of answers I saw for the similar questions advised to us
The only character that needs escaping in a string is a single quote (which is done with two single quotes together). Otherwise, it's a string and t-sql will fuss with it no further.
If you're using a LIKE statement, see this SO topic Escape a string in SQL Server so that it is safe to use in LIKE expression
As an aside, any framework that doesn't let me use parameters, that doesn't properly escape stuff for me, is a hard stop. Trying to sanitize string input manually is like relying on the pull out method; eventually it's gonna get you.
