Checking the hibernate generated SQL in 6.1.5, reveals they are different:
2023-06-12 13:47:14,545 DEBUG Thread-163 [org.hibernate.engine.jdbc.spi.SqlStatementLogger] [logStatement] delete from TRUTH.FOLDER_FOLDER_LINK where FOLDER_ID=? and PARENT_FOLDER_ID=? and FOLDER_ID = ? and PARENT_FOLDER_ID = ? and LINK_TYPE_NAME = ?
I tried to debug the issue, and from my understanding hibernate generates a delete SQL statement, but when it comes to binding the input parameters, hibernate doesn’t bind all of them, resulting in the above error.
I’ve noticed some extensive work in hibernate 6.2 related to how the SQL is generated: HHH-15393 - Improve write-paths to use mapping model by sebersole · Pull Request #5620 · hibernate/hibernate-orm · GitHub ( https://github.com/hibernate/hibernate-orm/pull/5620 ). Maybe there is a regression in this area?
