> SqlWriter in SqlInsert's unparse() start a list but does not end it.
> There is a SparkSql :
> {code:java}
> with tmp as (select * from t1) insert into t2 select * from tmp {code}
> I know calcite doesn't support parse "CTE + DML" for now.
> But in some situation, I'll create a SqlNode like that.
> {code:java}
> SqlInsert sqlinsert;
> SqlWith sqlWith;
> // ....
> sqlWith.setOperand(1, sqlInsert);
> sqlWith.toString(); {code}
> if we put a SqlInsert into a SqlWith's body manually, when we unparse the
> SqlWith , it will throw an Expception :
> {code:java}
> java.lang.IllegalArgumentException: Frame does not match current frame
>
> at com.google.common.base.Preconditions.checkArgument(Preconditions.java:122)
> at
> org.apache.calcite.sql.pretty.SqlPrettyWriter.endList(SqlPrettyWriter.java:884)
> at org.apache.calcite.sql.SqlWith$SqlWithOperator.unparse(SqlWith.java:109)
> {code}
