Hi!

What's the best way of changing the order of fields in a MySQL database.

eg. There are 4 fields in a table.

id
surname
firstname
password

How do you change the order to...

id
password
firstname
surname


Cheers,

Mel

Why do you want to change the order of the fields? For the display, you can (and should) always query the fields in the order you want, and if you are developing a software on your own, you don't care the order.
I'm not sure, but MySQL should support views, in which you can order the fields as you like, and issue the SELECT * FROM YourView as you want...

The main reason is for commands like...

INSERT INTO table VALUES ('abc','123','etc','etc');


It makes life a little easier for me.

Cheers,

Mel

If you build the view(s) as i mentionned, you should be able to insert into the view also...
Not sure because i'm not MySQL expert, but that works for all the databases i know of (SQL Server, Oracle, Access)

So what's wrong with giving a column list?

INSERT INTO table (id, password, firstname,surname)
VALUES ('abc','123','etc','etc');

angel, I don't believe MySQL supprts views.

Arjan, thanks for your input. Your solution will work, but ideally I still want to change the field order.

Cheers!

As i said, i'm not a MySQL expert...
But in any database, you can only drop and recreate the table. To maintain the data, you can copy it to a temporary table...
