Songkong feature comparison2/19/2023 Public static List getSongDiffs(StatelessSession session, List ids) SQLQuery q = session.createSQLQuery("select * from SongDiff where recNo = ANY(:recNos)") Public static List getSongDiffs3(StatelessSession session, List ids) SQLQuery q = session.createSQLQuery("select * from SongDiff where recNo in :recNos") Public static List getSongDiffs2(StatelessSession session, List ids) (Level.SEVERE, "Failed to get SongDiffsFromDb:" + e.getMessage(), e) GetSongDiffs1() is my initial Hibernate based Criteria query, getSongDiffs2() is query rewritten to use native sql works but has no performance advantage, I then tried using ANY for getSongDiffs2() and ARRAYS with getSongDiffs() but these gave errors when preparing statementsĪlthough I am trying to use native SQL because generated from Hibernate session I am working with rather than Connection so couldnt fully follow solution labelled Postgres solution at given PreparedStatement IN clause alternatives? public static List getSongDiffs1(StatelessSession session, List ids) But I have not yet been able to get this working However I cannot move to Hibernate 5, and it seems this solution has been superceded by use of ANY clause or ARRAYS anyway. This is a solution in Hibernate 5 called _clause_parameter_padding as described at So I am trying to reduce the need for so many different prepared statements. If the number of values in the IN clause vary then a different prepared query needs to be prepared, existing ones cannot be reused. I create an html report made up of many pages and I have to make a larger number of queries simply with the where clause based on an IN call based on the primary key.
