> when i unparse the following sql

> {code:java}
> String sql = "select concat(a.id,'-',b.id) , a.name from xxx.bb where dt between '2020-10-04' AND '2020-10-09' limit 2";
> {code}
> i got the result

> {code:java}
> SELECT `CONCAT`(`A`.`ID`, '-', `B`.`ID`), `A`.`NAME` FROM `XXX`.`BB` WHERE `DS` BETWEEN ASYMMETRIC '2020-10-04' AND '2020-10-09' LIMIT 2
> {code}
> the "ASYMMETRIC" keyword is not supported in spark dialect. and the "parser.jj" file defines optional "ASYMMETRIC" and "SYMMETRIC" keyword.

> but "SqlBetweenOperator" writes the "flag" in hard code way.

> the parse and unparse should keep the same syntax process.
> my code is as follows

> {code:java}
> String sql = "select concat(a.id,'-',b.id) , a.name from xxx.bb where dt between '2020-10-04' AND '2020-10-09' limit 2";
> SqlParser sqlParser = SqlParser.create(sql, configBuilder); try { SqlNode sqlNode = sqlParser.parseQuery(); SqlString sqlString = sqlNode.toSqlString(SPARK); System.out.println(sqlString); } catch (SqlParseException e) { e.printStackTrace(); }
