java - Hibernate generates error SQL like ".=." -

-

i have 3 tables in oracle db relationship @manytomany. have 2 significant tables , 1 mappings.

i create classes name (if want can show classes) named entities, keywords (i understand naming not correct not project optimizations).

i use hibernate version 4.3.4.

i write query this:

        session = hibernateutil.getsessionfactory().opensession();         string sql = "select distinct r rules r, entities e " +                 " r.entities = e.rules " +                 "  , e in :entities ";          query query = session.createquery(sql);         query.setparameterlist("entities", entitieslist);          list<rules> ruleslist = query.list();

but! hibernate generate strange sql

hibernate:  select     rules0_.rule_id rule_id1_11_,     rules0_.rule rule2_11_      rules rules0_,     entities entities1_,     rules_entities entities2_,     entities entities3_,     rules_entities rules4_,     rules rules5_      rules0_.rule_id=entities2_.rule_id      , entities2_.entity_id=entities3_.entity_id      , entities1_.entity_id=rules4_.entity_id      , rules4_.rule_id=rules5_.rule_id      , .=.     , (         entities1_.entity_id in (             ? , ? , ? , ?         )     )

when try execute query receive error: java.sql.sqlexception: ora-00936: missing expression

when copy query oracledevepoler didn`t expression "and .=.". without query executes correct.

what doing wrong ?

maybe used bad join in query? context conclude should use that:

"select distinct r rules r inner join r.entities e " +                 "  e in :entities ";

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
