OK so I have read the docs and Google to try and find a way to add a
new column to an existing table. My problem is I need this new column
to be created 3rd rather than just dumping this new column to the end
of my table. I can't find anywhere how I can insert my new column as
the 3rd table column rather than the last (seventh). Does anyone know
how I can accomplish this or if it's even possible. Seems like a
common task but I checked the documentation and may have missed it in
my reading.
It isn't possible at the moment. This has come up a good bit in the
past, so you'll find debate in the archives...
One work-around is to add the column, and then do:
create table new_table as
select [columns in desired order] from old_table;
drop table old_table;
alter table new_table rename to old_table;
...remembering to deal with foreign key constraints as you go.
