Thread: 7.3 -> pg_atoi: zero-length string
Hi
After I upgraded 7.2.3 to 7.3 I started to get the following errors:
pg_atoi: zero-length string
its seems that i get it when not all field have content:
this is one example that generate the error:
insert into images (section_id, pic_date, image_order) values ('8',
'2002-12-03', '')
Hi, one of the changes in 7.3 was to disallow '' being implicitly
converted to 0. In your example below image_order is clearly not a
text/char column, so what are you trying to set it too? If you want it
be 0 then explicitly use 0, if you want it to be undefined then use
NULL.

That's indeed very nice but I don't see the logic in it.
If I want to upgrade I need to go on all my projects and change thousands of
lines.
And that's not all :(
I have other applications like phprojekt that was not developed by me and
became useless now as I cant insert.
Was this step so necessary ?

Was it necessary? No idea, you're welcome to search through the
pgsql-hackers archives to determine the reasoning behind the change. I
believe the change was made by Bruce Momjian (going by the release
notes). I only remember reading the discussion in passing.
This is also one of the reasons for beta releases - to allow people to
test against the new version and pick up these sort of things. Either
this gives them/you time to make changes, or to lobby to get the old
behaviour back.
If I were in your situation i'd probably hack back the old behaviour
to 7.3, compile and run that while changes were made. Or stick with
7.2.x until changes were made to your applications, have you got a
'big carrot' for going with 7.3?

The change was made to tighten up the code to catch errors sooner.
There isn't much logic to making '' be 0, and no one could make a case
for keeping such a mapping.

Then Why not set it to NULL
Seems logic as there is nothing between ''
What is the solution of other dbs ( oracle, db2 .. ) to:
insert into table (num) value (''); ?
Who knows how many application will suffer becouse of this.

Well, it is not NULL, though, it is ''. They are not the same in
strings (though for some dbms's they are), so I don't see why we would
do that for numerics.

I assume they would fail too.

Yours is the first, or perhaps second to bring up this issue.
I am sure it is a pain, but it does tighten up some cases where we were
silently mapping '' to 0, and we don't exactly have a flood of problem
reports.

I don't think many will be caught-out, since it's an overwhelmingly
daft thing to do anyway!
If you've got a numeric type column then assign numeric values to, not
strings. Or explicitly convert.
I'm sure all occurrences of this "in the wild" are due to sloppy
SQL...

He's at least the 2nd. I have one, that I've complained to the
PHPGroupware folks (which
BREAKS severely with this change).

Oracle doesn't fail because it converts an empty string into
NULL. So the insert succeeds if the column lacked a NOT NULL
constraint. But Oracle's treatment of empty strings as NULL *is
insane*. Not sure about DB2...

If we had received more complaints about the change during beta, we
would have added a mention that the change would be in 7.4. As we got
few complaints, the change went into 7.3, and it is mentioned in the
porting section of the release notes (last item):
* An empty string ('') is no longer allowed as the input into an
integer field. Formerly, it was silently interpreted as 0.

Well I already fixed all my application, it was quiet easy though more code
was entered :(
like:
if ( !is_numeric($var) )
$var = 0;
I hope the other projects will fix compliance fast.
maybe this feature should be enabled when compiling ?

Same as in the INSERT case:
iidbdb=# SELECT version();
version
-----------------------------------------------------------
PostgreSQL 7.3 on i686-pc-linux-gnu, compiled by GCC 2.96
(1 row)
iidbdb=# SELECT int4('');
ERROR: pg_atoi: zero-length string
iidbdb=# SELECT CAST('' AS int4);
ERROR: pg_atoi: zero-length string
