It's already there. iBATIS is setting the fetch size properly. The issue
is that his JDBC driver is not honoring the fetch size on the result set.
We don't have anything in iBATIS that allows changing result set attributes
after they are generated by the driver.
It might not be so bad to add this call after the result set is generated -
don't know if there are any other implications?

add a commandTimeout property to statement /. That's probably going to
happen too.
Perhaps Raga should be encouraged to write a patch, submit it to JIRA, then
if no one has major objections it can be added instead of encouraging him to
make an internal fork.

If you feel you need this, then you could easily hack iBATIS to set the
fetch size on a result set. Add these lines to the beginning of the
handleResults method in
com.ibatis.sqlmap.engine.execution.DefaultSqlExecuter:
Integer fetchSize = statementScope.getStatement().getFetchSize();
if (fetchSize != null) {
rs.setFetchSize(fetchSize.intValue());
}
Before you ask, I'll state that we will probably not add this to the
official iBATIS2 code base. But this is the true beauty of open source -
you can modify the code to make it work the way you need it to work!

Jeff,
Many thanks for your reply.
We are using iBATIS 2.3.0.
fetchSize set on StoredProcedure gets set on the CallableStatement. But
unfortunately does not get percolate to the ResultSet when the application
is running on Weblogic server.
A point to note is that we are running our application in the same JVM as
the weblogic server.
Thanks,
Raga

What version of iBATIS are you using? With versions 2.2.0 and later,
iBATIS will set the fetchSize on stored procedure calls - and that should
translate to the result set (according to the JDBC spec).
iBATIS does not support setting the fetchSize directly on a result set.

Hi,
We are having issues with the prefetchSize property that is available at
the procedure element (of ibatis sqlmap). Even though we set the prefetch
size to a value, say 100, ibatis ignores this and always defaults to 10
(jdbc driver default). Also our application is a weblogic based J2EE app
running in the same JVM as the weblogic server. Hence the prefetchSize set
on the callableStatement will not work.
But prefetchSize set on the resultSet level will work perfectly(after
getting the resultSet from the callableStatementt).
Hence, in IBatis we need to set the prefetchSize at the resultSet level
while executing a storedproc.
We dont seem to find a way to do this in ibatis at the moment.
Is this a limitation/bug or is there a way around this?
Any help here will be much appreciated.
thanks,
Raga
