Hi,
given this legacy informix table:
~~~
create table kperson
(
name varchar(80, 1) not NULL,
age integer not NULL,
primary key (name)
);
I did:
>>> db.define_table("kperson",
... Field("name"),
... Field("age"),
... primarykey=["name"],
... mig
Hi,
afaik informix supports limiting resultsets with keword 'FIRST' since
version 9.0 and skipping (=offset) with keyword 'SKIP' since version
10.0. The web2py default implementation 'LIMIT x OFFSET y' does not
work with informix!
The following patch to sql.py would implement informix's behavior
database support is only available for MS SQL,

Unfortunately I have not been able to find more information about this
issue. :-(
Desperately waiting for support of informix non "id" / non integer
primar
Did that:
>>> db = DAL("sqlite://db.db")
>>> db.define_table("t1", Field("f1", "date"))
>>> db.t1.insert(f1="a")
1
>>> db.t1[1].f1
