No migration were detected by the drizle when I changed from this ```ts buildDate: integer("created", { mode: "timestamp" }) .notNull() .default(sql`(unixepoch())`), buildYear: integer(), ``` to this ```ts buildDate: integer("created", { mode: "timestamp" }) .notNull() .default(sql`(unixepoch())`), buildYear: integer().generatedAlwaysAs( (): SQL => sql`CAST(strftime('%Y', ${vehicles.buildDate}, 'unixepoch') AS INTEGER)`, { mode: "stored" } ), ```
