============================================================================

                        POSTGRESQL BUG REPORT TEMPLATE
============================================================================



Your name  :  Bob Rivoir
Your email address : rhr2@psu.edu


System Configuration
---------------------
  Architecture (example: Intel Pentium)   : AMD Athlon

  Operating System (example: Linux 2.0.26 ELF)  : OpenLinux eDesktop 2.4

  PostgreSQL version (example: PostgreSQL-7.0):   PostgreSQL-7.0.2

  Compiler used (example:  gcc 2.8.0)  : gcc egcs-1.1.2 release


Please enter a FULL description of your problem:
------------------------------------------------
I got the following error message when I tried to do an INSERT using
SELECT ... ORDER BY:

ERROR:  ORDER BY is not allowed in INSERT/SELECT


Please describe a way to repeat the problem.   Please try to provide a
concise reproducible example, if at all possible:
----------------------------------------------------------------------





If you know how this problem might be fixed, list the solution below:
---------------------------------------------------------------------

Unless I'm horribly misreading the spec, this is correct.
ORDER BY is used in reference to cursor definitions and
direct select statements, but is not part of query expressions
which is what the INSERT INTO references.

         <insert statement> ::=
              INSERT INTO <table name>
                <insert columns and source>

         <insert columns and source> ::=
                [ <left paren> <insert column list> <right paren> ]
              <query expression>
              | DEFAULT VALUES

         <insert column list> ::= <column name list>

But, this may be a useful extension to allow, at least with the
existance of LIMIT.

Yes, added to TODO.

Is 7.1 able to do INSERT/SELECT with ORDER BY and LIMIT ?
