asp.net - Identity column increment jump -


this question has answer here:

i experiencing funny in database. primary key increases like:

1 2 3 4 5 6 7 8 1001

i'm using entityframework or linq sql.

it happens when sql server 2012 loses pre-allocated sequence numbers.

if want rid of that, 1 option use traceflag:

dbcc traceon (272)

another option use sequence (with no caching) instead of identity:

create sequence myseq int   start 1   increment 1   no cache;
