I generated an sql script like this, INSERT [dbo].[TableName] ([Sno], [Name], [EmployeeId], [ProjectId], [Experience])

I generated an sql script like this,

INSERT [dbo].[TableName] ([Sno], [Name], [EmployeeId], [ProjectId], [Experience]) 
VALUES (1, N'Dave', N'ESD157', N'FD080', 7)

I wonder whats that N’ exactly mean and whats its purpose here.

NOTE: By searching for the answer all i can get is that N’ is a prefix for National language standard and its for using unicode data. But honestly i am not able to get a clear idea about the exact operation of N’ here. I’d appreciate your help and please make it in more of an understandable way. Thanks in advance.

    N is used to specify a unicode string.

    Here’s a good discussion: Why do some SQL strings have an ‘N’ prefix?

    In your example N prefix is not required because ASCII characters (with value less than 128) map directly to unicode. However, if you wanted to insert a name that was not ASCII then the N prefix would be required.

    INSERT [dbo].[TableName] ([Sno], [Name], [EmployeeId], [ProjectId], [Experience]) 
VALUES (1, N'Wāhi', 'ESD157', 'FD080', 7)
