Thread: Position of a field

Position of a field

From

Hi list,

I just would like to know if it is possible to change the position of
a field in a table. I am seen in pgAdmin3 that there is a position but
on th is application I can't see if there is a place to do that.

Regards
Ezequias

Why do you want to do this? You can define the order of the fields in
the SELECT-Statement. Other way: you can create a VIEW. And another way:
you can recreate the table (create new_table as select <cols in desired
order> from old_table, drop old_table, rename new_tabel to old_table)

I understant you inquiry but I don't meant to add all the fields order
in an insert statement.

IE:
insert into table values (value1, value2, value3....)

is better than

insert into table (column1,column2,column3 ...) values (value1,
value2, value3....)

If there is only one way (recreating) that was not good for me.

No, it isn't better, because, if you change the table in the future and
add new colums, your insert-statement will be failed. If you write your
insert with explicit column order, nothing happens, except the new row
will be empty.
