View as plain text  
Kudos for managing to drag up such an obscure piece of functionality :-) I
can see where it would be useful, though.

As to your question, though: given that that page indicates that it will
reuse deleted sequence numbers, I think your best bet would be select @id :=
count(*)+1 from table where cluster='clusterA' AND file='fileA' ; - should
be slightly faster than a max(), I think. That in a trigger on your table
should emulate the behaviour pretty closely.

Am I mistaken, or does your code try to start from sequence 0 ?
