Special Character in SQL

Question

I have a problem with a special character inserted in a table of SQL Server 2008 R2. The point is that when i\'m trying to insert a string with the character º (e.g. 3 ELBO

Answer 1

The degree symbol

U+00B0 ° degree sign (HTML: ° °)

is not an ASCII character and generally requires an NVARCHAR column and a N'' string literal. (except for codepages etc that support the symbol)

63 is the code of the question mark, which is the fallback for your inverse question mark in ASCII:

select UNICODE('�') => 63
select UNICODE(N'�') => 65533

where 65533 is the Unicode Replacement Character used to display characters that could not be converted or displayed.
