Nathan Xu ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *commented* on HHH-14153 ( https://hibernate.atlassian.net/browse/HHH-14153?atlOrigin=eyJpIjoiOTU1NW... ) Re: HQL update query with multiple condition generates temporary tables on SQLServer ( https://hibernate.atlassian.net/browse/HHH-14153?atlOrigin=eyJpIjoiOTU1NW... ) Sorry for my misunderstanding. The ticket description is a little bit misleading. I don’t know too much about this, but as per https://in.relation.to/2005/07/20/multitable-bulk-operations/ , the temporary table creation seems justified for the class inheritance here is ‘JOIN’ based.
