             Summary: Sql.  Unclear weird messages from parser
                 Key: IGNITE-20104
                 URL: https://issues.apache.org/jira/browse/IGNITE-20104
             Project: Ignite
          Issue Type: Improvement
            Reporter: Yury Gerzhedovich


We have issue with unclear messages from parser, when user can't understand 
what is went wrong and where is error.
As example of such errors:
1. {code:java}
MERGE INTO TBL_ALL_COLUMNS_SQL(key, str) VALUES(?, ?)
{code}
{noformat}
TraceId:5e59762a-2252-4ac0-bc1f-8ec53112b858 Failed to parse query: Encountered 
"" at line 1, column 35.
Was expecting one of:
{noformat}
2. {code:java}
ALTER ZONE TEST_ZONE WITH REPLICAS = 2
{code}
{noformat}
IGN-SQL-3 TraceId:5be71235-eb40-424f-b3f7-0488fd0076ca IGN-SQL-3 
TraceId:5be71235-eb40-424f-b3f7-0488fd0076ca Failed to parse query: Encountered 
"" at line 1, column 24.
Was expecting one of:
{noformat}

Parser can show all alternatives related to syntax to user have ability 
understand is mistake
