Sorry, but I don't fully agree with you. If I have to add a new column
in a table, this column will appear in the end of the table. What we are
talking about (as I understand) is to have the possibility to order the
columns table (via ALTER TABLE ...POSITION..). SELECT * FROM <table>
would use that order to display the columns.
We are not talking of changing columns order for each kind of SQL query.
In that case, I agree that views are usefull and when we want to
display several tables in one "pseudo-table" (a view) and to have less
big queries.
I really think that column ordering (ALTER TABLE ...POSITION..) is very
interesting and will allow users to avoid loosing time when they have to
create a new temporary table each time they have to add a new column
inside (not at the end of) a table, and rename the table after deleting
the old table... :-)
