[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-2692) Insert Into Select command doesn't allow named parameter as select output (insert input)

[Alvin Lim (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-2692?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=31695#action_31695 ] 

Alvin Lim commented on HHH-2692:
--------------------------------

I have a similar problem.

SELECT a.id, b.name, :date
FROM tab1 a, tab2 b
WHERE a.id = b.id
AND a.date < :date

The named parameter :date can't be used in the SELECT clause. I can't use a sub-select here, as it may not be the case that the parameter value will exist in table a or b.

In my opinion, this feature should ideally be implemented by creating a new HQL function which works as follows:

SELECT a.id, b.name, NEWFUNCTION(:toDate)
FROM ....

Is there an existing function that works the same way? I can't think of any other workaround for this problem, other than creating a new Hibernate mapping to a new table with a single row then inserting the parameter value into the row (which is even more stupid :D)

> org.hibernate.QueryException: number of select types did not match those for insert [INSERT INTO ProviderInvoiceLineItem (amount,billingAccount,circuit,description,invoice,type) SELECT pili.amount, pili.billingAccount, pili.circuit, pili.description, :newInvoice, pili.type FROM com.cicat.bedrock.billing.model.ProviderInvoiceLineItem pili WHERE pili.invoice = :oldInvoice]
> Idea is to copy all line items from one invoice to another. In other words, only difference between data should be the invoice. easiest way to do this is with "insert into" command and passing parameter of changed value.
>  * Trying to cast named parameter (:newInvoice) caused parsing error
>  * Trying to replace invoice with invoice_id and repacing :newInvoice with actual invoice id resulted in a "property 'invoice_id' not found" exception
> Should be able to set a value through a named parameter
