Hi everyone,

I'm beginner on Odoo12 and I'm trying to update a data in the database using custom module, but it's not working.

Thanks for your help.

class IrSequence(models.Model):
    _inherit = "ir.sequence"

    @api.model
    def _update_sequence(self):
        cr = self._cr
        cr.execute("SELECT id FROM ir_sequence WHERE name = 'BILL Sequence' LIMIT 1")
        sequence_data = cr.fetchone()

        if sequence_data:
            cr.execute(
                "UPDATE ir_sequence SET name='INV Sequence', implementation='standard', prefix='INV/%(range_year)s/', use_data_range=0 WHERE id = %s",
                (sequence_data[0]))
            return True
