Reset AutoNumber(Identity Field) in Database

I Use a Sql Server Compact Edition Database File For Store the Data in My Windows Application Software.

In this database I have a table with an identity field.

When I insert a record into the T开发者_如何转开发able, the identity code increments automatically. But when I delete all the records from the table, and insert some records again, the identity field doesn't start at 1.

How can I reset this value to 1?

DBCC does not exist in CE, but you can use this instead:

ALTER TABLE t1 ALTER COLUMN id IDENTITY (1,1)
