Andrus,
I've found the problem and solved it. Which leads me to the question:
Why doesn't the MySQLAdapter quote column names?
The not quoting of column names actually bites me here because I have a
column named 'group' - once I renamed it, everything works as expected.
There are many tools out there that handle spaces, umlaut and other
weird
things in column names fine - I guess it would just be better if cayenne
would do so too.
JMHO,

I just double checked. My cayenne.xml contains:
<node name="mysql"
datasource="mysql.driver.xml"
adapter="org.objectstyle.cayenne.dba.mysql.MySQLAdapter"
factory="org.objectstyle.cayenne.conf.DriverDataSourceFactory">
<map-ref name="mysql"/>
</node>
Versions:
Cayenne Release Notes 1.2 B3 (beta)
mysql Ver 14.7 Distrib 4.1.14, for redhat-linux-gnu (i386) using
readline 4.3
I did some more work, but couldn't get any further,

A corresponding Cayenne unit test works on all version of MySQL
between 4.0 and 5.0 (tested column type as 'longblob', but I don't
think it matters). So what version do you have?
Another thing to check - are you actually using MySQLAdapter (or
1.2 auto adapter)? Is it possible there is an adapter mixup.

Hi,
When I try to insert a new row into my image database using this
code:
File imgFile = new File(TEMPFILE2);
InputStream imgStream = new FileInputStream(imgFile);
long imgStreamLength = imgFile.length();
byte[] imgData = new byte[(int)imgStreamLength];
int offset = 0;
int numRead = 0;
while(offset < imgData.length && (numRead=imgStream.read
(imgData, offset, imgData.length-offset)) >= 0)
offset += numRead;
imgStream.close();
Images img = (Images)context.createAndRegisterNewObject
(Images.class);
img.setName("jei");
img.setGroup("medarbetare");
img.setType("image/jpeg");
img.setX(new Integer(160));
img.setY(new Integer(120));
img.setImage(imgData);
context.commitChanges();
Cayenne fails with this error:
QueryLogger: INSERT INTO images (group, image, name, type, x,
y) VALUES (?, ?, ?, ?, ?, ?)
QueryLogger: [bind: 'medarbetare', < 89 50 4E 47 0D 0A 1A 0A
00 00 00 0D ...>, 'jei', 'image/jpeg', 160, 120]
QueryLogger: *** error.
java.sql.SQLException: Syntax error or access violation
message from server: "You have an error in your SQL syntax;

at line 1"
Images is defined as:
CREATE TABLE `images` (
`name` varchar(64) NOT NULL default '',
`group` varchar(64) NOT NULL default '',
`type` varchar(64) NOT NULL default '',
`image` blob NOT NULL,
`x` int(11) NOT NULL default '0',
`y` int(11) NOT NULL default '0',
PRIMARY KEY (`name`,`group`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1
and the relevant part in Images is:
public void setImage(byte[] image) {
writeProperty("image", image);
}
public byte[] getImage() {
return (byte[])readProperty("image");
}
Any pointers or ideas? I already tried changing the column type
but it
doesn't change anything.
