Hi,
sorry if I flood you with lots of messages, but I am quite new to
Postgresql and I find a lot of questions not answered in the manual.
I get randomly (probably when I have concurrent r/w access) the error
message
java.sql.SQLException: ERROR: SET TRANSACTION ISOLATION LEVEL must be called before any query
when I do a commit(). But I had set this level at the very beginning with
dbConn.setTransactionIsolation(Connection.TRANSACTION_READ_COMMITTED);
BTW, I tried to use TRANSACTION_READ_UNCOMMITTED (which is described
in the manual) but in this case I get "Transaction isolation level 1
is not supported."
What is wrong here? Why do I get an error message when I try to use
the "read uncommitted" level, and why I get the exception when I use
commit() after setting the transaction level to "read committed"?
Ciao
Ole
