If you want to have all values except the primary key be the same and
say your is foo_ID
You can simply do
INSERT INTO foo
(foo_ID... {rest of columns list})
SELECT new primary key value,
{rest of columns list}
FROM foo
WHERE foo_ID = {primary key value of row you want to copy}
If your PRIMARY KEY is an auto_increment field, just omit foo_ID from
the columns list in both the INSERT and SELECT.

Subject: SELECT ... INTO OUTFILE ... and LOAD DATA INFILE ... with a key
Hi listers
I once asked if there is an SQL syntax permitting to copy a row in the
same table. I got no answer, so there is no such syntax.
now i meant to have found a work-around using (see subject).
problem is, that when i do a SELECT * ... INTO OUTFILE .. i will also
catch the PRIMARY KEY column if there is one and the LOAD DATA INFILE
... of this file will fail because of duplicate keys. i tried to use the
FOREIGN_KEY_CHECKS=0 but obiousely this works on foreign keys not on the
primary key.
certainly, i can very very clumsily construct a SELECT at1, ... atn INTO
OUTFILE statement which selects all columns except the primary key.
the REPLACE and IGNORE constructs are not what i want either, because i
want to add a row in any case, not replace an existing one nore ignore
the action.
is there a more elegant way then the clumsy making of an attr list,
which includes alle columns except the primary key column?
thanks very much for your interest and understanding.
