Date Fri, 12 Feb 2016 12:01:18 GMT
Vladimir Ozerov created IGNITE-2641:
---------------------------------------

             Summary: Improve usability of "SELECT *" SqlQuery.
                 Key: IGNITE-2641
                 URL: https://issues.apache.org/jira/browse/IGNITE-2641
             Project: Ignite
          Issue Type: Task
          Components: cache
    Affects Versions: 1.5.0.final
            Reporter: Vladimir Ozerov
             Fix For: 1.6


*Case 1*:
{code}SELECT * FROM Employee e{code}
Result: exception:
Reason: query is expanded to 
{code}SELECT Employee._key, Employee._val FROM EMPLOYEE e{code}
instead of 
{code}SELECT e._key, e._val FROM EMPLOYEE e{code}

*Case 2*
{code}SELECT e.* FROM Employee e{code}
Result: exception
Reason: hard-coded check in IgniteH2Indexing.generateQuery():
{code}
if (!qry.startsWith("*"))
    throw new IgniteCheckedException(...);
{code}

*Proposed solution*
Instead of checking for asteriks, we must also check for "[table/alias].*" pattern.
