I would stick to INT, SMALLINT, BIGINT for primary keys. Depending on the numbers or rows in the table I need to store. /Andreas On Mon, Aug 30, 2010 at 1:39 AM, jms.cer...@gmail.com jms.cer...@gmail.comwrote: Hi, I would like some insight/opinions on using binary types for primary keys -

Hi, Is it a different client and server version? The error indicated version 1.1.119, not 1.2.140 ? I think somewhere along the line there was an issue where with different client and server versions. It outputs an error that doesn't make sense like what you are getting. So I think the

Hi, the test program (sometimes) produces JdbcSQLExceptions due to deadlocks. As I've read in other threads this seems to be not fixable? Although I was wondering that I've never seen such a problem before in other database systems?! This is a VERY nasty problem because I cannot expect that all

Binary data types as keys would make using database tools for adhoc queries practically impossible. That alone is enough to throw out the idea for me. In my world primary keys should always be meaningless, so an INT should always be just fine. Your binary fields don't sound meaningless to me, so
