While creating product, at the last step after retrieving for a time, Magento gives following error-:
SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '1922-1' for key 'IDX_STOCK_PRODUCT'
What I am doing is, by capturing product id, I am putting it's entry in custom table. I have connected to Magento database externally.
Surprisingly data is inserted in both Magento's base table & also in Custom table but why it is giving me that error after product saving...?
I cleared cache, browser cookies. Also remove /var/cache, /var/session. still giving error. Can anybody suggest a solution?

duplicates
Try to change the FK to INDEX instead of UNIQUE.
I just added an @ symbol and it started working. Like this: @$product->save();
your column value is already in database table it means your table column is Unique you should change your value and try again
You might have forgotten to auto increment the id field.
I also encountered this problem. I found after changing the table storage engine from MyISAM to Innodb, problem solved .
Many time this error is caused when you update a product in your custom module's observer as shown below.
class [NAMESPACE]_[MODULE NAME]_Model_Observer
{
/**
* Flag to stop observer executing more than once
*
* @var static bool
*/
static protected $_singletonFlag = false;
public function saveProductData(Varien_Event_Observer $observer)
{
if (!self::$_singletonFlag) {
self::$_singletonFlag = true;
$product = $observer->getEvent()->getProduct();
//do stuff to the $product object
// $product->save(); // commenting out this line prevents the error
$product->getResource()->save($product);
}
}
Hence whenever you save your product after updating some properties in your module's observer use $product->getResource()->save($product)
instead of $product->save()
