The column object.
Once a table introspection succeeds, it creates a new table object for every table it introspected. Within each table object, it also creates a column object for every column it introspected.
name non-null String
The column's name.
type non-null String
The column's type.
isNullable nullable Boolean
Whether the column is nullable, meaning whether it accepts a null value.
cachedAt non-null DateTime
The time at which the column was cached (i.e., the time at which it was introspected).
createdAt non-null DateTime
The time at which the column was created. This is the same as its
createdBy non-null String
The columns's creator. This corresponds to the initiator of the table introspection. It can be either a User ID, an Application ID, or "system" if it was created by Propel.
