[web2py] Databases problem

[Neveen Adel]

Hello all,

I have a deployed application. and by the time i need to add fields to
database so  appended the new SQLField into my database and removed
                                              Migrate = false


but finally i got the error :

 OperationalError: (1050, "Table 'member' already exists")



Is there any way to update easily into  database design?


Thanks in Advance
