Why do I have to use FOUR queries to accomplish the same result I can
get from MySQL with only ONE query:

alter table users add column $ColumnName text;
alter table users alter column $ColumnName set default '';
update users set t_shirt_size='' where $ColumnName is null;
alter table users alter column $ColumnName set not null;

Wow, that's true!


On MySQL 4.0.16-nt is also possible write:

alter table T1
add CONSTRAINT FK_test foreign key (id)
REFERENCES T2 (id);

that doesn't complain. Unfortunately repeating
the command N times doesn't complain neither.
And the funny here is that FK are not yet supported !
