Are there JPA - vendor neutral - query hints that can be used ? During my google searches on query hints every mention of it has been a vendor specific query hint.
From the doc:
Set a query property or hint. The hints elements may be used to specify query properties and hints. Properties defined by this specification must be observed by the provider. Vendor-specific hints that are not recognized by a provider must be silently ignored. Portable applications should not rely on the standard timeout hint. Depending on the database in use and the locking mechanisms used by the provider, this hint may or may not be observed.
I'm not sure I'm understanding this correctly. Does this mean that there are vendor neutral query hints or there are not ? If so where can I find a list describing those ?
