Hello List,
I want to change some columns in a database
that were originally created as char varying to
inet.
When I try I get an error. Is there anyway to work
around this?
See below for table definition.
Table "public.kernel_gre"
Column | Type | Modifiers
-----------------+-----------------------+---------------
interface | character varying(15) | not null
source_ip | character varying(16) |
dest_ip | character varying(16) |
physical_ip | character varying(16) |
status | boolean | default false
physical_src_ip | character varying(16) |
tunnel_netmask | character varying(16) |
key | character varying(32) |
state | boolean | default false
broadcast | boolean | default false
alter TABLE kernel_gre ALTER COLUMN source_ip TYPE inet;
ERROR: column "source_ip" cannot be cast to type "inet"
current table contents:
interface | source_ip | dest_ip | physical_ip | status | physical_src_ip | tunnel_netmask | key | state | broadcast
