Error Message: Debug error while inserting into database: 1SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '0' for key 1

My table schema:
ID[INT Primary Key] Auto increments
boxNumber[INT]
show[TINYINT UNSIGNED Nullable]
description[TEXT Nullable]
url[VARCHAR(100) Nullable]
purchased[TIMESTAMP]

There is only one record in the table with ID (primary key) of zero. Also, that record has a boxNumber of zero, even though I inserted a 1... not sure if that's related.

I am a TOTAL newbie when it comes to MySQL. I am using Eclipse with Zend on XP. If you need any other information, tell me what you need and how I go about getting it.

Thank you all VERY much.
$DatabaseObj = Zend_Registry::get('Instance/DatabaseObj');

$DatabaseObj->beginTransaction();
 

$data = array(

    	'description'    => $description,

    	'url' 		 => $urlAddress,

    	'purchased'      => $today,

	'boxNumber'      => $boxNumber);
 

// This line causes the exception...

$DatabaseObj->insert('tblImages', $data); 
 

// Therefore, this line never executes.

$DatabaseObj->commit();

where did you set $boxNumber

try hard coding the boxNumber (just once) and see if you still get the error. This would tell you that's it's something in the insert function.

I have tried to pass $boxNumber as other numbers but the insert statment is still throwing an exception.

The single row/record in the table has an ID of zero, and remember ID auto increments. So the second record I try to insert throws an exception, that I'm trying to insert another row/record with a duplicate ID of zero.

Notice I am not including the ID in the insert statement, that should automatically be provided and incremented, I thought.

try setting it. if it works then something is wrong with the way you defined the table.

do you have mysql admin? can you
describe table_name;
$data = array(

        'ID'             => 1,

        'description'    => $description,

        'url'            => $urlAddress,

        'purchased'      => $today,

        'boxNumber'      => $boxNumber);
