View 3 RepliesI am developing a asp.net application and i am using SQL Server 2008. I took a IDENTITY column as Record_ID for detail table where i will have trillions of records per year. So just want to ask whats the largest number record id (identity) column can hold and in ASP.NET which data type i should use to handle record id as i am using this id as a reference to update the table data. I don't want to end up being trapped some day.

Resetting IDENTITY column to a new valueDuring application development we always entry some test data also our tester test with test data and as a result if the table contains IDENTITY columns( specially ID column) which incremented to the number of data already entered.
However, when the application goes running with real data to the client and the client want his ID values from starting 1, then we need to RESEED the value of the IDENTITY column of the table after clearing all data. This can be done as bellows:
DBCC CHECKIDENT (TableName, RESEED, 0)
However, can be reseed with any values instead of zero(0) in the above statement.
I have an identity column that increment by 1 on every insert. I have deleted all the rows using delete query but the identity coulumn is still not reseting to zero, how do i reset it, as it was when the table was first created.
