This problem is well known to me.
We do it the same way.
It is much easyier because it is not neccessary
to analyze for changes.
Cayenne does not commit the changes in a fifo-logic.
To solve this we use a separate context
for delete and insert ...

Hi,
I have a Product & a ProductRelation tables. When the ProductRelation
records for a product are managed in a web page, I'd like to delete the
exiting records in the ProductRelation table for this product first, then
insert the new one.
I'm having trouble to do this with the following code. I got the "Cannot
insert duplicate key in object ..." db error. The reason appears that the
DELET statements appear after the INSERT statements from what I can see in
the QueryLogger output. Could someone please help? I'm using Cayenne 1.2B2.
The code:
=========
public void saveProductRelation(Product product, String
relatedProductId[], Type relationType)
{
// delete the existing records
log.debug("product.getProductRelationArray().size()=" +
product.getProductRelationArray().size());
threadDataContext().deleteObjects(product.getProductRelationArray());
if (relatedProductId.length
> 0)
{
for
(int i=0; i<relatedProductId.length; i++)
{
log.debug("relatedProductId["
+ i + "]=" +
relatedProductId[i]);
ProductRelation
o = new ProductRelation();
threadDataContext().registerNewObject(o);
o.setToProduct(product);
o.setToProduct1((Product)
objectForPK(Product.class, new
Integer(relatedProductId[i].trim())));
o.setToType(relationType);
product.addToProductRelationArray(o);
}
}
commitChanges();
}
The QueryLogger output:
=======================
dao.ProductDaoImpl.saveProductRelation(ProductDaoImpl.java:713) -
<relatedProductId[0]=9>
cayenne.access.QueryLogger.logQueryStart
(QueryLogger.java:459) - <--- will
run 2 queries.>
cayenne.access.QueryLogger.logBeginTransaction(QueryLogger.java:413) - <---
transaction started.>
cayenne.access.QueryLogger.logQuery(QueryLogger.java
:336) - <INSERT INTO
dbo.ProductRelation (ProductId, RelatedProductid, TypeId) VALUES (?, ?, ?)>
cayenne.access.QueryLogger.logQueryParameters(QueryLogger.java:358) -
<[bind: 242, 9, 16]>
cayenne.access.QueryLogger.logUpdateCount
(QueryLogger.java:404) - <===
updated 1 row.>
cayenne.access.QueryLogger.logQuery(QueryLogger.java:336) - <DELETE FROM
dbo.ProductRelation WHERE ProductId = ? AND RelatedProductid = ? AND TypeId
= ?>
cayenne.access.QueryLogger.logQueryParameters(QueryLogger.java:358) -
<[bind: 242, 222, 16]>
Many thanks in advace!
