Question

Im new to SQL SERVER , I was going through some of the examples in MSDN . I understood what OBJECT_ID does. but i was confused the way it was in the example .

USE tempdb;

GO

IF OBJECT_ID (N’#Bicycles’,N’U’) IS NOT NULL

DROP TABLE #Bicycles;

Why are we writing N and # ?

Thanks in advance

Answer 1

Typically the # symbol prefixes a temporary table name and N denotes type NCHAR, NVARCHAR or NTEXT.
