Re: How to generate sequence in MySql

[Arshad Mahmood]

Somebody really should add sequence support to mysql. Yes, it is great that we have an auto-increment column.

But I have just come across a use-case that is a killer in this respect.

I am starting a new project and looking to use JBoss/Seam and it's conversation support for long running tasks. Everything was looking great until I came across the problem that I can't use mysql, because hibernate will automatically do an insert if the identity generation strategy is used (i.e. it will not wait for a flush which is essential for long running tasks).

I suppose I can go to Postgres as that supports sequences (which are ok because no insert to the database is required).

Somebody, please help us out and add sequence support to mysql. Unless there is someway to define some user defined functions that can help us out (anybody?)
