Returns all items from the given table name in the closest scope.
If no tables with the given name are in scope, returns an empty
iterator.

This is wrong for zero-arity relations, because we can't
distinguish between "no such table" and a table that exists but has no
columns. The current design of scope makes this difficult to fix,
unfortunately.
Returns all items from the given table name in the closest scope . If no tables with the given name are in scope returns an empty iterator . This is wrong for zero - arity relations because we can ' t distinguish between " no such table " and a table that exists but has no columns .
