Question

Making the Auto Incrementing number within an SQL Server 2000 table, reset to 0

Asked by: doyle007

I have a table in an MS SQL Server 2000 database that has an auto incrementing  ID number.
Can someone tell me what causes the number to increase and how can I reset it to 0.
If I add a record manually into the table the ID increases as well.

Hello doyle007,

DBCC CHECKIDENT (UrTableName, RESEED, 0)

The auto increment causes the column to always increase by 1. Either you delete an entire column or not the specific column will never take the same value again. So if for example u add 5 records the column with autoincrement will go from 1-5. Now if you delete those rows and u add new 5 , the auto increment column will start from 6.
You can choose autoincrement when you want to have a unique column in order to set a primary key. So if you really need it keep it like this and reset it with the way aneesh mentioned.

As said above, this field have incremental values as defined in the column defination/at the time of table creation, every time you insert a values to this table it will increment the value of this identity column based on the defination. i.e. Id column has identity value set to 1 and increment value to 1, if this table has 3 records and you insert a new record this will add a new record with value 4 in id. If you delete this records and insert records  again it will starts from 5.  And if you wants to start this from the 0/1 you can use dbcc checkident(table,reseed,value)

Please refer BOL for more explaination on DBCC Checkident

If you want to keep the records in that table (as mentioned by aneeshattingal), you can use:

            DBCC CHECKIDENT (<TableName>, RESEED, 0)


Else by doing:

            Truncate Table <TableName>

You will remove all records from that table and also reset the Identity...
