Reset autoincrement in Microsoft SQL Server 2008 R2
I created a primary key to be autoincrement. I added two rows: ID=1, ID=2 I deleted these two rows. I added a new row, but the new row's ID was: ID=3 How can I reset or restart the autoincrement to 1? If you use the DBCC CHECKIDENT command: DBCC CHECKIDENT ("YourTableNameHere", RESEED, 1); But use with CAUTION! - this will just reset the IDENTITY to 1 - so your next inserts will get values 1, then 2, and then 3 --> and you'll have a clash with your pre-existing value of 3 here! IDENTITY just dishes out numbers in consecutive order - it does NOT in any way make sure there are no conflicts! If
