In the below fuction I want to update  "account_bank_statement" table field balance_end_real with the vale balance_end. i.e "update account.bank.statement set balance_end_real=balance_end where id=ids"


"def _compute_difference(self, cr, uid, ids, fieldnames, args, context=None):
        result =  dict.fromkeys(ids, 0.0)

        for obj in self.browse(cr, uid, ids, context=context):
            result[obj.id] = obj.balance_end_real - obj.balance_end

        return result  "

It seems that balance_end_real field already in the same model (or inherited) with the method you defined. In that case you don't need to use update sql manually, just use write method.

self.write(cr, uid, ids, {'balance_end_real': obj.balance_end}, context=context)


Thank you very much. This is the best answer

You can use "cr.execute" to update record based on id. Refer the following example:

cr.execute('update account_period set state=%s where id=%s', (mode, id))

Use "cr.execute" and update directly using sql update statement...
