What does N' stands for in a SQL script ? (the one used before characters in insert script)

Question

I generated an sql script like this,

INSERT [dbo].[TableName] ([Sno], [Name], [EmployeeId], [ProjectId], [Experience]) 
VALUES (1, N\'Dave\', N\'ESD157\', N\         


        

Answer 1

The "N" prefix stands for National Language in the SQL-92 standard, and is used for representing unicode characters.

Any time you pass Unicode data to SQL Server you must prefix the Unicode string with N.

It is used when the type is from NVARCHAR, NCHAR or NTEXT.
