Subject [jira] [Created] (IGNITE-4247) Table aliases not supported for SqlQuery
Date Fri, 18 Nov 2016 19:11:59 GMT
Valentin Kulichenko created IGNITE-4247:
-------------------------------------------

             Summary: Table aliases not supported for SqlQuery
                 Key: IGNITE-4247
                 URL: https://issues.apache.org/jira/browse/IGNITE-4247
             Project: Ignite
          Issue Type: Bug
          Components: SQL
    Affects Versions: 1.7
            Reporter: Valentin Kulichenko


Here is the example of the query:
{code}
from Person p where p.salary > ? and p.salary <= ?
{code}
Ignite is not aware of the alias and incorrectly appends the SELECT statement, which causes
this exception:
{noformat}
Exception in thread "main" javax.cache.CacheException: Failed to parse query: SELECT "CacheQueryExamplePersons".Person._key,
"CacheQueryExamplePersons".Person._val from Person p where salary > ? and salary <=
?
