temporary table, then "REPLACE" it back into "b".
In case anyone wants to know how to do an UPDATE ... SELECT FROM ...,
I did the equivalent of:
BEGIN;
ALTER TABLE b ADD Col3 ...;
CREATE TABLE CopyCol3
SELECT b.id, b.Col1, b.Col2, a.Col3
FROM b
LEFT JOIN a
I have a table "a" with:
ItemID int unsigned not null,
CommID int unsigned not null
I have a table "b" with:
ItemID int unsigned not null
I want to move CommID from table "a" to table "b". I've updated my schema
to have CommID in "b" as well for now, and changed my code to insert the
value in
