Subject:Re: No tuples, but AttributeError about tuple!
View as plain text  
You were right about the % I'd forgotten. Still, I got the same error. So I
tried to change the command to this:

insert into products (ID, Name, Title, Description, Price, Bedrooms,
Bathrooms, Conditions, Acreage, Construction, Location, Estate, Address,
Furnished, pic1, pic2, pic3, pic4, pic5, pic6) values("1", "name1",
"title1", "descr1", "1.1", "2", "1", "New", "1.5", "new", "princesse",
"princesse", "123 princesse", "Not furnished", "", "", "", "", "", "");

Here's the table description:

(
ID int(3) unsigned primary key auto_increment,
Name varchar(40),
Title varchar(3),
Description varchar(512),
Price float(10,2),
Bedrooms int(1) unsigned,
Bathrooms int(1) unsigned,
Conditions varchar(255),
Acreage float(5,2),
Construction set('New','Existing'),
Location varchar(256),
Estate varchar(60),
Address varchar(100),
Furnished set('Furnished','Unfurnished'),
pic1 blob,
pic2 blob,
pic3 blob,
pic4 blob,
pic5 blob,
pic6 blob
)

Now I get this error:

Is it me, or does this actually make sense?
