[jira] [Created] (FLINK-18111) LATERAL query failed when use create view syntax

YufeiLiu created FLINK-18111:
--------------------------------

             Summary: LATERAL query failed when use create view syntax
                 Key: FLINK-18111
                 URL: https://issues.apache.org/jira/browse/FLINK-18111
             Project: Flink
          Issue Type: Bug
          Components: Table SQL / API
    Affects Versions: 1.11.0
            Reporter: YufeiLiu


When execute sql like this will throw exception "org.apache.calcite.sql.validate.SqlValidatorException: Column 'c1' not found in any table":

{code:SQL}
CREATE VIEW my_view AS SELECT T.a, T.b FROM source, LATERAL TABLE(MY_TABLE_FUNCTION(`c1`)) AS T(`a`, `b`)
{code}

Because of in {{SqlToOperationConverter#convertCreateView}} unparse SqlNode to sql string after validate, but the LATERAL keyword was missing at this point. Plus {{SqlNode validateQuery = flinkPlanner.validate(query)}}, query == validateQuery.
I think we could use original sql to build {{CatalogViewImpl}}, they have the same functionality.
