How to remove invisible characters in t-sql?

Question

I tried

UPDATE TABLENAME SET COLUMNNAME = REPLACE(COLUMNNAME, \'\\t\', \'\')

But I don\'t know how to write the TAB in t-sql

Answer 1

I found the solution:

In T-SQL you do not escape characters, you paste or type them directly into the quotes. It works even for \r\n (carriage return, new line = you press enter)
