Get Column Name

[Rakesh Nair]

Hi,
I would like to know whether there's any way to *get the column names of
the table once it has been scanned*.


*RelBuilder builder = RelBuilder.create(config);*

*builder.scan("emp");*
*List<RexNode> ls = builder.fields();*

I've tried the *builder.fields() method*, but the return object is
containing names like $0, $1 etc..

Is there any way, I can actually get the column names itself from the
builder?

Regards,
Rakesh
