INSERT Query Question

[Charles Givre]

Hello Calcite team, 
I have a quick question.  I'm looking to take an INSERT query, parse it and 
convert it into the dialect of various databases.  The Inserts will not be 
complicated.  For instance:

INSERT INTO mysql_test.data_types 
        VALUES(1, 2, 3.0, 4.0, '5.0', '2020-12-31', '12:00:00', '2015-12-30 
17:55:55')

Converted into:

Postgres: INSERT INTO "postgresl_test"."data_types"
VALUES ROW(1, 2, 3.0, 4.0, '5.0', '2020-12-31', '12:00:00', '2015-12-30 
17:55:55')
MySQL: INSERT INTO `mysql_test`.`data_types`
VALUES ROW(1, 2, 3.0, 4.0, '5.0', '2020-12-31', '12:00:00', '2015-12-30 
17:55:55')
MSSQL: INSERT INTO [mssql_test].[data_types]
VALUES ROW(1, 2, 3.0, 4.0, '5.0', '2020-12-31', '12:00:00', '2015-12-30 
17:55:55')

I wrote a function that does this, however as you'll note above, that Calcite 
is inserting the word ROW before each row to be inserted and this is not 
correct SQL. 

public static String cleanQuery(String query, SqlDialect dialect) {
  SqlParser.Config sqlParserConfig = SqlParser.configBuilder()
    .setParserFactory(SqlDdlParserImpl.FACTORY)
    .setConformance(SqlConformanceEnum.MYSQL_5)
    .setCaseSensitive(true)
    .setLex(Lex.MYSQL)
    .build();

  try {
    SqlNode node = SqlParser.create(query, sqlParserConfig).parseQuery();
    return node.toSqlString(dialect).getSql();
  } catch (SqlParseException e) {
    return null;
  }
}

Is there some way to configure Calcite not to insert the word ROW?  Thanks!
