[jira] [Updated] (IGNITE-17746) Fix multistatement query execution flow.

     [ https://issues.apache.org/jira/browse/IGNITE-17746?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Andrey Mashenkov updated IGNITE-17746:
--------------------------------------
    Description: 
As for now SqlQueryProcessor.query0 methods run statements in parallel.
Let's make query statement execution consequent.

Also, statement cancellation may cause unexpected behaviour:
* The {{query0}} method returns list of futures for each statement in multi statement query,
cancellation of a statement does't affect other statements.
* Failed statement doesn't cancel other statements. Thus, following statements may return wrong results in this case.

Also, statement cancellation may cause unexpected behaviour.
The {{query0}} method returns list of futures for each statement in multi statement query,
cancellation of statement in the middle does't affects previous statements futures.
