I have an existing table that uses an auto-incremented id
as its primary key.
There are entries in the table with the id starting at 1:
id field1
== ======
1 foo1
2 foo2
3 foo3
Is there a way to update the id
for all existing entries so the auto_increment starts at another number?:
id field1
==== ======
1000 foo1
1001 foo2
1002 foo3
(The order does not necessarily have to be kept if that is not possible)
You can use update
to change the values and alter table
to update the auto increment to a new value:
alter table t set auto_increment = 1003; -- the next value
update t
set id = id + 999;
In Sql Server it is work, MySql I'm not sure
DECLARE @NewRowId int = 998;
DBCC CHECKIDENT('MyTableName', RESEED, @NewRowId)
