{code}
which is (according to https://www-01.ibm.com/support/docview.wss?uid=swg21570296 link) the following:
"When using the JDBC driver, one connection instance can only execute a single query at a time. This means that if one query is already executing on a specific connection instance, no other queries can be sent for parallel execution. If you run multiple queries using the same connection instance, you might encounter an error similar to the following:
Error[1]: Failed retrieving bean metadata.netezza.max.stmt.handles"
Another interesting thing is that running pretty the same query but not like insert, just usual select:
{code:sql}
select t1.* from views.v t1 join (call views.pr()) t2 on t1.a=cast(t2.a as integer)
where
t1.a >= (select max(t1.a) from views.v t1 join (call views.pr()) t2 on t1.a=cast(t2.a as integer))
and
t1.a1 >= (select min(t1.a1) from views.v t1 left join (call views.pr()) t2 on t1.a=cast(t2.a as integer)) limit 10000 ;;
{code}
will work without any errors.
