What is the N string prefix in SQL Server?

Question

Khushi Singh · Answer

In SQL Server, an N string prefix is used to distinguish between Unicode and non Unicode strings. It also helps in making sure that the string is of unicode that is NVARCHAR rather than non unicode that is VARCHAR. This is useful where there are large amounts of data that contain multilingual, or other characters not normally included in ASCII chart. Key Points:N Prefix: The N stands for “National” or “Unicode”.When used, it will be treated as Unicode; it is used in an NVARCHAR column or variable/format to store it. Usage: Put the N before the string literal in SQL. Example: Hope it helps!
