RelBuilder from SQL Query

[Christophe Le Saëc]

Hello,

I used RelBuilder to scan table name without any pb.
Now, i would like to do same kind of transformation, but instead of table
name, with a SQL query.
Something like
RelBuilder.scanSQL("Select x, y from ...");

I try to use SqlParser / SqlToRelConcerter

SqlNode sqlNode = SqlParser.create(sqlQuery).parseQuery();
SqlToRelConverter => build RelRoot

but didn't find a way to convert SqlNode nor RelRoot to RelBuilder in order
to modify the request.

Is it possible ? And if yes, how ?

Best regards,
Christophe.
