Convert PostgreSQL Dump to MySQL
been searching for a while, but cannot find a suitable answer..yet.
I'm trying to rebuild a site (currently Ruby/PostgreSQL) into PHP/MySQL.
I have a PostgreSQL dump .sql file, which looks like:
CREATE TABLE addresses ( id integer NOT NULL, firstname character varying(255), lastname character varying(255), address1 character varying(255), address2 character varying(255), city character varying(255), state_id integer, zipcode character varying(255), country_id integer, phone character varying(255), created_at timestamp without time zone, updated_at timestamp without time zone, state_name character varying(255), alternative_phone character varying(255) ); ALTER TABLE public.addresses OWNER TO XXXXXX; CREATE SEQUENCE addresses_id_seq START WITH 1 INCREMENT BY 1 NO MAXVALUE NO MINVALUE CACHE 1; ALTER TABLE public.addresses_id_seq OWNER TO XXXXXX; ALTER SEQUENCE addresses_id_seq OWNED BY addresses.id; SELECT pg_catalog.setval('addresses_id_seq', 348, TRUE);
COPY addresses (id, firstname, lastname, address1, address2, city, state_id, zipcode, country_id, phone, created_at, updated_at, state_name, alternative_phone) FROM stdin; 1 Mr CustomerA 1 New St Somewhere \N PS1 2BC 213 07XXX XXX XXX 2010-06-24 11:44:25.130213 2010-06-24 12:35:14.501107 SomeState \N 1 Mr CustomerB 2 New St Somewhere \N PS2 3AB 213 07XXX XXX XXX 2010-06-25 11:00:25.130213 2010-06-25 12:00:14.501107 SomeState \N
Thanks in advance

1. convert your CREATE TABLE statements manually, in a text editor
you might be able to find a conversion program to do this, but i wouldn't bother, as you need to inspect every datatype and change them appropriately
for example, state_id and country_id are suboptimal (INTEGER is clearly too large, but using international character codes would be even better), zipcode as VARCHAR(255) is silly, timestamps need to be rethought, etc.
2. write some application code to insert field separators in the appropriate places in the data file, then use LOAD DATA INFILE to load them
