Question

I cant use truncate table in sql server CE (annoyingly) so I use:

drop table mytable

However when I re-insert rows the Ids pick up where they left off. Is there any way to start the Id’s from scratch again?

Answer 1

Enter DBCC CHECKIDENT:

Checks the current identity value for the specified table and, if it
is needed, changes the identity value.

Usage:

USE AdventureWorks;
GO
DBCC CHECKIDENT ('HumanResources.Employee', RESEED, 30)
GO

In your case

Use YourDBName
GO
DBCC CHECKIDENT('YourTableName', RESEED, 0)
GO

Replace YourDBName with your database name, and replace YourTableName with the name of your table, and reseed the value, the last parameter (the 0 in this case) will reseed your ID to that value.

Edit

Just read that DBCC CHECKIDENT is not available in CE edition.

In this case use ALTER TABLE tableName ALTER COLUMN ID Identity (999, 1)

(999 is the new max of the ID column)…
