Thread: what is the difference between default 0 vs default '0'

all-
Could somebody tell me why I would use default 0 vs default '0' in the
following....
CREATE TABLE foo (col1 INTEGER default 0) <-- or default '0'

Thanks-
Beth

Hi Beth,

I wouldn't have thought there'd be any difference to you, the user.

If you used 0, then that is an integer and that will be the default.  If you
used '0' then that is a character or string and it will automatically be
cast into an integer when used as a default.

0 is an integer
'0' is a string

default '0' might work (through type coercion)
but I think default 0 is more clear.
