tsql - What is the 'N' when you are dealing with SQL such as (N'') -

just in question, not sure difference between '' , n'' in sql.

it's shorthand nvarchar. using notation tells parser treat next string info nvarchar instead of default varchar.

example:

select n'this test'; -- nvarchar info select 'test test'; -- varchar info

sql tsql
