Subject [jira] [Created] (IGNITE-4182) Improve error output when query parsing failed.
Date Mon, 07 Nov 2016 13:36:58 GMT
Igor Sapego created IGNITE-4182:
-----------------------------------

             Summary: Improve error output when query parsing failed.
                 Key: IGNITE-4182
                 URL: https://issues.apache.org/jira/browse/IGNITE-4182
             Project: Ignite
          Issue Type: Task
    Affects Versions: 1.7
            Reporter: Igor Sapego
            Priority: Minor


There is no enough information in the exception when SLQ query can not be parsed. In most
cases we get something like this:
{noformat}

a FROM B, args=[]]]

In this particular case, for example, we do not have table "B", nor we have column "a", but
you can't get it from the exception.
