- This is kept for backwards compatibility
- There may be cases that uses the join parameter, which
has no replacement in the new prepare.
This should likely be handled by an override an dedicated
constructor. if this complicates stuff and join really is
needed add a prepare(buffer,ITableRequest,join)
Parameters
@param buffer - client temp-table buffer in dataset
@param clientquery - query from client expressed on the temp-table buffer
must in principle be passed if active parent relation or builtquery is empty,
but an empty query is valid when requesting all data
@param pcjoin - optional join to a parent
