Worth noting that the code you see is sent to the database as is  the queries are sent separately to prevent SQL injection  AFAIK The   marks are placeholders that are replaced by the number params by the database  not by hibernate

Can I see       the real SQL   If you want to see the SQL sent directly to the database  that is formatted similar to your example   you ll have to use some kind of jdbc driver proxy like P6Spy  or log4jdbc    Alternatively you can enable logging of the following categories  using a log4j properties file here    log4j logger org hibernate SQL DEBUG log4j logger org hibernate type TRACE   The first is equivalent to hibernate show sql true  the second prints the bound parameters among other things   Reference   Hibernate 3 5 Core Documentation    3 5  Logging   Hibernate 4 1 Core Documentation    4 1  Logging

If you can already see the SQL being printed  that means you have the code below in your hibernate cfg xml    lt property name  show sql  gt true lt  property gt    To print the bind parameters as well  add the following to your log4j properties file   log4j logger net sf hibernate type debug
