I'm reading through "SQL Server 7.0" WROX book (highly recommended by many) and I noticed that their naming convention for field names do not use "c" or "i" or "n" (or anything else) before the field names to denote TYPE. (Example = nCustomerNumber, cName, tOrderDate)

Usually in XBase examples, you see everyone doing this.
However, in SQL I see this less. Anyone have any thoughts on this? What are your normal procedures? Is it a 'waste' of time to do this in SQL or something?

Thanks!
