org.apache.metamodel.query.FromItem
Represents a FROM item. FROM items can take different forms:
- table FROMs (eg. "FROM products p")
- join FROMs with an ON clause (eg. "FROM products p INNER JOIN orders o ON p.id = o.product_id")
- subquery FROMs (eg. "FROM (SELECT * FROM products) p")
- expression FROM (any string based from item)
