JDBC setQueryTimeout not working?

问题:

I'm querying MSSQL 2008 server thourgh JAVA, using the JDBC driver. I do something like this:

PreparedStatement stmt = ...;
...
stmt.setQueryTimeout(60);
stmt.executeQuery();

I see that when there's a load on the SQL server, the statement doesn't get cancelled even though the timeout has passed.

Does anyone have a clue about this?

Thanks.

回答1:

• The timing for setQueryTimeout is not precise at all
• The exception relies on the server acknowledging the cancel command

So, YMMV unfortunately...
