Reset AutoNumber in SQL

    Question

  • Hi everyone,

    I recently migrate a DataBase from Microsoft Access in a replication scenario with those evil replication autonumbers to SQL Server 2008 R2

    The PK of all tables where the replication autonumbers in access.

    I want to keep the same PK with there values but I would like to know if it's possible to make the auto-number restart at beginning to fill empty "range". At the moment, it increment starting at the highest value. So if I have those PK (1, 2222, 3333, 5555) I would like that the next value is gonna be 2 instead of 5556

    Do I also have to execute a script (if it's possible) against every table of the database ?

    Thanks for the help

  • Hi Richard:

    RESEED will helps u reset the auto identity value.

    A table has 116 rows with 116 as last identity. The next record will automatically genrate 117, If you wants to start the new identity as 444 use the follwing T SQL query in query analyzer.

    DBCC CHECKIDENT (tableName, reseed, 444)

    Hopes this helps....
