Hi all,

I have a legacy schema from an accounting system that for licensing
reasons puts multiple datasets in one ms-sql server database.

All tables (with no exceptions) contain a 3-char column called
"dataset", which identifies the dataset to which a row belongs. The
datasets are completely independent of each other and are in fact the
financial books for otherwise unrelated companies.

Could I write a mapper_extension (or something similar) that would add
"where table.dataset = X" for all tables in all selects, inserts and
updates automatically, preferably with X being read from a property on
the connection?
