Why would the query timeout at all ?

The query timeout is for long running queries. If the query takes longer than n seconds it will timeout.

Hi,
does setQueryTimeout work with autoCommit=false? When autoCommit is true, this code timeouts after 5 seconds (as expected):
--
Class.forName("org.postgresql.Driver");
String url = "jdbc:postgresql://172.30.100.6/test";
Properties props = new Properties();
props.setProperty("user", "postgres");
props.setProperty("password", "");
Connection conn = DriverManager.getConnection(url, props);
PreparedStatement st = conn.prepareStatement("INSERT INTO test VALUES('xxx')");
st.setQueryTimeout(5);
st.execute();

But if I set autoCommit to false, this code timeouts after 30 seconds on read timeout:
--
Class.forName("org.postgresql.Driver");
String url = "jdbc:postgresql://172.30.100.6/test";
Properties props = new Properties();
props.setProperty("user", "postgres");
props.setProperty("password", "");
Connection conn = DriverManager.getConnection(url, props);
conn.setAutoCommit(false);
PreparedStatement st = conn.prepareStatement("INSERT INTO test VALUES('xxx')");
st.setQueryTimeout(5);
st.execute();
conn.commit();
--
I'm confused what's setQueryTimeout() method for, why it doesn't work with manual transactions?
Thanks,
Regards
Pavel
