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
depending on dbms-version:
suse101:~/web2py-1436/gluon # diff sql.py.ori sql.py
2906a2907,2915
> elif self._db._dbname == 'informix':
> fetch_amt = lmax - lmin
> dbms_version =
> int(self._db._connection.dbms_version.split('.')[0])
> if lmin and (dbms_version >= 10):
> # Requires Informix 10.0+
> sql_s += ' SKIP %d' % (lmin, )
> if fetch_amt and (dbms_version >= 9):
> # Requires Informix 9.0+
> sql_s += ' FIRST %d ' % (fetch_amt, )
Massimo, can you apply this patch?
Regards,
Hans
