The following TSQL statement block creates a new Global Uniform Identifier(GUID). Most of your primary key columns can be of uniqueidentifier datatype and you can use it during insert of rows in your T-SQL block or stored procedure

Note: GUID is a 32 byte alpha-numeric string representation and its value depends on the system.



declare @guid uniqueidentifier
set @guid= NEWID()
print 'Value of @guidis: '+ CONVERT(varchar(255), @guid)
