Searching for the fastest possible bulk insert it does not make sense to copy the data into another table before you import it to the database.<br> What makes a difference is usage of sequences, sessionless processing and maybe using prepared statements - performance wise.<br> So this test shows and compares performance of different approaches to implement a fast bulk insert. The performance of these implementations cannot be improved without changing how hibernate itself - at least that is my conclusion. <br> The syntax I use in the named query is only there to fullfill the syntax requirements of hibernate. I am intentionally using parameters to fill in the data into the insert statement. I do not want to copy any existing table content! This is new data. I know that it is not working but it should be possible to use a named query for a bulk insert, why not?<br> I am not aware of any test like this in hibernate that compares the fastest ways to implement a bulk insert in hibernate. <br> In the meantime I learned that hibernate is not able to use the MSSQL sp_sequence_get_range stored procedure to get full performance on bulk insert.<br> So I am sorry to causing confusion. If there was an explanation why the tests fail without the patch to the hibernate code the pull request contains I would still be interested to know.<br> Anyway - thank you for your time! </p> </td>
