RE: Table Definitions DDS or SQL?

Mike,

In that instance, the SQL way to handle the issue would be to create a
view over the table with the fields in the order you want them.

Again, the physical order of the fields in the table is not supposed to
matter.

If for whatever reason you want to see the fields in a particular order,
then you use a view.

You could even have move the data to a new table and created the view
with the name of the old table.

HTH,

Charles Wilt

Subject: RE: Table Definitions DDS or SQL?

Field sequence does not matter to applications but it does matter to
users who do queries. Getting all the fields in a table that 
are related
together makes queries easier to do. An example: Being a college we
record SAT scores for students. SATs use to have just two scores Math
and Reading and existed for many years and are near the "front" of the
fields in the student master table. SAT when added another test which
was added to the end of the existing table with about 30 
fields between
the original two and the new SAT score. It would be nice to have the
three SAT scores in the same location in the table. CHGPF 
will let me do
that, ALTER TABLE will not unless I want to do the old unload/reload
process of all the data and use CPYF *MAP to do the reload

Can ALTER TABLE be used to rearrange fields in the file 
like CHGPF
can? 

No, but remember that the order of fields in an SQL table aren't
supposed to matter.
