Hi,

what about generic DAO pattern? (IBM generic DAO pattern)

Best regards,

Hi,

i have the following HQL and want to create an equivalent Criteria:



Person2.java:


The generated SQL loooks like this and works as expected:


With Hibernate Criteria i tried this:


But Hibernate generates the follwogin SQL:


As you can see, the generated SQL for the "anrede1" association is not correct. My question is, how can i set a projection for an association inside my criteria? ((Projections.property("anrede1"),anrede1) doesn't work...)?

Thanks in advance.

Best regards,

peter
Hi,

i am using Hibernate Criteria with "Query by Example" and have some problems when i set "nullable=false" for OneToMany mapping inside my entities.
The problem is, that the generated SQL query is not the one i expected.

Here is my example code:

Person.java:


PersonenStichwort.java:


PersonenDao.java:


SQL Query generated by Hibernate:


As you can see, Hibernate inserts "personenst1_.bp_personenid=?" inside the sql-where-clause, cause personenStichworte in Person.java is mapped with "nullable=false". How can i force Hibernate to exclude this property without
changing nullable to true? (I have already tested Example.create(personenStichwort).excludeProperty("bp_personenid"), but doesn't work as well)

Best regards

Peter
