Smsd with win, odbc, mysql does not set delivery report

[odibox]

Hi

I have a problem to send an sms with delivery report if i use windows, odbc and mysql.
service = sql
driver = odbc
host = smsd
sql = mysql
If i use service = files everything works fine.
Version is 1.37.91

I think the problem is in file sql.c on line 1007
Config->currdeliveryreport = db->GetBool(Config, &res, 9);

The structure in the mysql database for the DeliveryReport is
DeliveryReport enum('default','yes','no') DEFAULT 'default',

I think that there's a problem with the enum Datatype and the Getbool function.

It doesn't matter if i use default, yes or no. The delivery report doesn't work. 'SendingOkNoReport'

If i change the DeliveryReport field to char and set it to '1'. The delivery report function works. 'SendingOk'

Thank you very much for your help.
