Hi,
I have trouble on making a query between two tables:
ProcessedDataset
- ID
ProcDSParent
- ThisDataset
- ItsParent
To find the `Parent` and `Child` of a `Dataset`, I need explicit
specify the join sequence between:
`ProcessedDataset` -- `ProcDSParent` -- `ProcessedDataset`

Dear Michael,
Appreciate for help me solving this problem.
Meanwhile I found something interesting, maybe worth to tell you.
Two alias object of same table with same name are treated as conflicts when
both using in query.
Error 1066, Not unique table/alias is throwing.
Many regards,
