I needed to quote an identifier (a column name) with “<“. I checked the documentation for the build-in function QUOTENAME() and I did not find the information that I need. Here is a quick T-SQL to show which characters we can use as a second argument of the function.
DECLARE @Counter SMALLINT = 1;
WHILE (@Counter <= 255)
IF (QUOTENAME(@Counter, CHAR(@Counter)) IS NOT NULL)
PRINT CONCAT(@Counter, ' --> >', CHAR(@Counter), '< --> ', QUOTENAME(@Counter, CHAR(@Counter)))
SELECT @Counter += 1;
Keep it simple :-)
