Thread: Change of data type

    Hello everybody, excuse me how can I change de data type of a field, 
I currently have:     material character(30)  
   but I now want the field in text type like this:    material  text
   somebody knows if ALTER TABLE has some option to do this?, or How 
can I do that?

On pg8, to change tab.col to type t:
 alter table tab alter column col type t

so: alter table tab alter column material type text

-j

You can do the following:

ALTER TABLE table-name ALTER colum-name TYPE text;
