Re: SET TRANSACTION ISOLATION LEVEL - Mailing list pgsql-jdbc

Philip,

It would be useful to see the rest of your code. It is hard to determine
what is going on.

Subject: [JDBC] SET TRANSACTION ISOLATION LEVEL



Hi

I got this error, it isn't the first transaction since the server was
started, so I don't understant what it means. The docs seem to suggest
that the READ COMMITTED level is default. If there is a default, why do
I need to set it?

I am AFAIK running single threaded in my java code, so I don't think I
would be dong two separate transactions in the same connection.

postgres 7.1. and this code involved is to get large objects, so it is
non-auto-commiting.

thanks,
PHilip
