CREATE TABLE AS and ORDER BY

От

Hi,

I tried to use CREATE TABLE AS and ORDER BY.  The query is as followed:

create table freshhr21 as
select e.studentid, u.hoursxfer
from enrollmentstatus e, undergradclass u
where e.studentid = u.studentid and e.classtd = '1'
order by u.hoursxfer

But, it returns error message "ERROR:  parser: parse error at or near
"order"".  Does "create table as" support "order by" inside of it?

I am using PostgreSQL 6.5.3.

Thank you.

Evidently not.

It seems to work in 7.0 and later.

Hey,

Try:

select e.studentid, u.hoursxfer into freshhr21
from enrollmentstatus e, undergradclass u
where e.studentid = u.studentid and e.classtd = '1'
order by u.hoursxfer

When you CREATE TABLEs you don't say anything about ordering.  I should say
it doesn't matter what the order is.  When you SELECT from the table you can
use ORDER BY.
