BindableTableScan is losing aliased named

[Enrico Olivelli]

Hi,
I have a ProjectableFilterableTable, it seems to me that the BindablaScan
RelNode does not keep track of column name aliases in the original
projection

Example:

Query:SELECT k1 theKey FROM tblspace1.tsql where k1 ='mykey2'

-- Logical Plan
LogicalProject(THEKEY=[$0])
  LogicalFilter(condition=[=($0, 'mykey2')])
    EnumerableTableScan(table=[[tblspace1, tsql]])

-- Best Plan
EnumerableInterpreter
  BindableTableScan(table=[[tblspace1, tsql]], filters=[[=($0, 'mykey2')]],
projects=[[0]])

Is this correct ?
IMHO It would better to keep somethin like an EnumerableProjection which
renames the fields

Am I missing something ?
Thanks
Enrico
