[Lift] Re: Extend the tables that like the migration in the Rails ?
Schemifier only adds, it does not remove. You have to do destructive
operations manually.
However, you can register for callbacks on column adds (e.g.,
MappedField.dbAddedColumn). You could use this function to look for an
existing column that needs to be removed.

1):
### I add a column in the User model, like this
class User extends MegaProtoUser[User] {

/* add column dos4 */
object dos4 extends MappedBoolean(this)
...
}
result: INFO - ALTER TABLE users ADD COLUMN do4 SMALLINT

2):
### I remove a column in the User model, like this
class User extends MegaProtoUser[User] {

result: Don't remove the cloumn dos4.

How can i remove the column in the liftweb (change the structure of
the table), just like the execute raw SQL statement.
execute(SELECT * from users) # Rails code in Migration

Ex:

I add this code in the User model and restart the server, the table
