Surely the first reseed statement fails because of the use of 'RESEED' as a quoted string and not a keyword? The second reseed statement demonstrates its correct use.

This looks very similar to the question about a week ago... So a nice easy way to end a friday. 🙂

No, either is allowed. Try it and see!

I figured a half-hour of research on this question was more than enough. I accept my fail. At least I didn't cheat! 😀

And since I've never reset an identity value in 20 years, I feel okay not knowing this. 😉

+1 BTW, as written the code given should error. Wouldn't it be better to add an IF EXISTS ... to the first statement?

I don't recall doing it for anything other than development, or for a permanent temp table used for, say, importing EDI transactions, etc.

Unfortunately - yes 🙁

I saw the mentioned QOTD after I had sent my question app. 1 week before!

I would have expected that my question would not be posted short after the first one 🙂

Happy new year to all...

I have only ever used the reseed option in dev. However, I had used it recently enough to get this one right! 😀 Thanks for the question Uwe.

Since transactional replication worked in standard edition of SQL 2000 while log shipping and other cleverer backup methods didn't (so implied increased licence costs for enterprise edition) and MS agreed with the interpretation of licensing terms that I didn't have to pay a SQL Server licence fee for the replica (because it was a standby copy) I used replication to provide a recovery copy. Testing recovery required resetting identity values, since the identity property had to be marked "not for replication", so I did a lot of resets for that purpose. I also did some for real when hardware problems entailed disaster recovery and forced it on me. So I made very sure that I and anyone else who might find themselves looking after recovery knew how identity reset worked.

I guess, Ron, that either you were in a situation where money was easier so you could use other recovery methods, or you didn't have contractual very short term recovery times.
