sql server programming:
You can either truncate the table or run DBCC CHECKIDENT with the RESEED
option. See the Books Online for details.

How to reset the identity value to 1 after all rows have been deleted? Oscar

After that I deleted all rows within a table which holds an identity column,
I want to have the next inserted row to start with the ID = 1 value.
However, SQL Server 2K assigns an ID value to the identity column which is
one higher that the ID-value of the last row that was deleted. How can I
reconfigure the column such that the first additional row should have an
ID=1 value ?

I'll bet that you are mimicking a sequential file system.

Can you explain why you have an IDENTITY column in the first, in
relational terms? Surely you know better than to use it as a key, since
it cannot ever be a key by definition. But if you made it a PRIMARY KEY
by mistake then what does resetting it with new data mean in relational
terms?

This question is a veryu good sign that you are doing everything wrong.
