[Zope-dev] ZOracleDA and select LONGs, for more than one row.

[Anthony Baxter]

(wah. www.zope.org/Collector gone away)

Can someone verify that I'm not going insane? Doing a select on a
table with a column of type LONG works, but only where the select
returns a single row. Any that returns more than one row breaks with
an IndexError (exception included below).

given the following table:

SQL> desc testlongs ; 
 Name                            Null?    Type
 ------------------------------- -------- ----
 ID                                       NUMBER(38)
 DATA                                     LONG

And the following SQL method:

    select * from testlongs 

It works when there's only one row in the result.

SQL> insert into testlongs values ( 1, 
	'helllohelllohellllhelllohelllohelllohehellohello' ) ; 
SQL> insert into testlongs values ( 2, 
	'helllohelllohellllhelllohelllohelllohehellohello' ) ; 

    select * from testlongs where id = 1
works.
    select * from testlongs where id = 2
works.

    select * from testlongs where id < 3
fails, with 
exceptions.IndexError: 1

I've had a look at the code, and I really really can't see what's going
on here.

Anyone?
