+
+    Declare virtual columns with `t.virtual name, type: …, as: "expression"`.
+    Pass `stored: true` to persist the generated value (false by default).
+
+    Example:
+
+        create_table :generated_columns do |t|
+          t.string  :name
+          t.virtual :upper_name,  type: :string,  as: "UPPER(name)"
+          t.virtual :name_length, type: :integer, as: "LENGTH(name)", stored: true

+    *Hiroaki Izu*

+    necessary and potentially creates circular dependencies.

+
+        # Touches `updated_at`/`updated_on`.
+        Topic.increment_counter(:messages_count, 1, touch: true)
+        Topic.decrement_counter(:messages_count, 1, touch: true)
+
+        # Touches `last_discussed_at`.
+        Topic.reset_counters(18, :messages, touch: :last_discussed_at)
+
+        # Touches `updated_at` and `last_discussed_at`.
