             Summary: sql statement parser enhancement
                 Key: FLINK-11206
                 URL: https://issues.apache.org/jira/browse/FLINK-11206
             Project: Flink
          Issue Type: Improvement
          Components: Table API & SQL
    Affects Versions: 1.7.0, 1.6.2
            Reporter: ambition


change calcite-core to calcite-server, use SqlDdlParserImpl to parse sql. 
SqlDdlParserImpl extends its grammar on the basis of SqlParser, which supports 
much more grammar than SqlParser, such as:
{code:java}
create or drop schema;
create or drop table;
create or drop view;
...{code}
favorable for subsequent expansion and enrichment.
