| | | | | | | | | | | | This is useful for dynamically created predicates e.g: expr1 = table.create_false expr2 = table.create_false expr1 = create_a_predicate() if some_condition expr2 = create_another_predicate() if some_other_condition table.where(expr1.and(expr2))

* Make ToSql more thread safe.Damon McCormick + Cameron Walters2011-05-101-0/+17
| | | | | | | Because the ToSql visitor instance is shared across all threads, there is a race condition around column types for binary nodes. It's possible, for instance, to end up with ActiveRecord converting a string value in the final SQL to an integer during heavy concurrent operations.
