Subject [jira] Commented: (IBATIS-22) Specify Query Timeout

Juergen Hoeller commented on IBATIS-22:
---------------------------------------

FYI, we support something similar in Spring: transaction timeouts that get applied as query
timeout for each SQL statement executed within a transaction (each statement with the remaining
timeout in the transaction, of course).

A timeout value can be specified in a Spring transaction attribute, applied to any operations
performed with that particular transaction. The framework does its best to interpret the timeout
for the concrete transaction and data access strategy.

We currently support this for Spring's JDBC framework (automatically calling Statement.setQueryTimeout),
for Hibernate (automatically calling Query/Criteria.setTimeout), and for JDO (via our JdoDialect
strategy, beyond the JDO standard).

If we get an appropriate hook in the SqlMapClient API (for example a setTimeout method on
the SqlMapSession interface, which propagates the timeout to JDBC Statements), we'll add such
support for iBATIS too.

As a side note: The same effect can be achieved by wrapping the JDBC driver, automatically
applying remaining timeouts to all created Statements. However, it would still be nice to
have explicit support for timeouts in higher-level persistence APIs.

a message in the sf forum that using driver properties is a possible workaround. But it would
be really nice to have a per statement timeout.
