java - JPA criteriabuilder where statement -


i achieve following statement in criteriaquery.

  (event.time >= now()       or (event.time >= '$clubhours' && (`eventselecttype`.`type`='cafe' || `eventselecttype`.`type`='dj'))       or (event.endtime >= now() && (`eventselecttype`.`type`='festival' or `eventselecttype`.`type`='dj' or `eventselecttype`.`type`='cafe'))) 

i tried following ;

eqr.where(         cb.or(             cb.or(                     cb.greaterthanorequalto(eventroot.<date>get("time"), curdate)                    ),             cb.or(                     cb.and(                     cb.greaterthanorequalto(eventroot.<date>get("time"), cal.gettime())                     ),                         cb.or(                                 cb.equal(eventtype.<string>get("type"), "cafe"),                                 cb.equal(eventtype.<string>get("type"), "dj")                                 )                 ),             cb.or(                     cb.and(                     cb.greaterthanorequalto(eventroot.<date>get("endtime"), curdate)                     ),                         cb.or(                                 cb.equal(eventtype.<string>get("type"), "festival"),                                 cb.equal(eventtype.<string>get("type"), "dj"),                                 cb.equal(eventtype.<string>get("type"), "cafe")                                 )                 )         ),         cb.equal(eventroot.<integer>get("id"), eventid),         cb.equal(eventroot.<integer>get("active"), 1)         ); 

but generates 1 big or statement

(event0_.time>=? or event0_.time>=? or eventselec13_.type=? or eventselec13_.type=? or event0_.endtime>=? or eventselec13_.type=? or eventselec13_.type=? or eventselec13_.type=?) 

how result i'm looking for?

edit

i have this

predicate eventtypeiscafeordj = cb.or(         cb.equal(eventtype.<string>get("type"), "cafe"),         cb.equal(eventtype.<string>get("type"), "dj")     ); predicate eventtypeisfestivaldjorcafe = cb.or(         cb.equal(eventtype.<string>get("type"), "cafe"),         cb.equal(eventtype.<string>get("type"), "dj"),         cb.equal(eventtype.<string>get("type"), "festival")         );      predicate timegreaterorequalto = cb.greaterthanorequalto(eventroot.<date>get("time"), cal.gettime());     predicate endtimegreaterorequalto = cb.greaterthanorequalto(eventroot.<date>get("endtime"), curdate);     predicate equaltoid = cb.equal(eventroot.<integer>get("id"), eventid);      eqr.where(timegreaterorequalto, cb.or( cb.and( timegreaterorequalto, eventtypeiscafeordj ), cb.and(endtimegreaterorequalto, eventtypeisfestivaldjorcafe )), equaltoid); 

which outputs

where event0_.time>=? , (event0_.time>=? , (eventselec13_.type=? or eventselec13_.type=?) or event0_.endtime>=? , (eventselec13_.type=? or eventselec13_.type=? or eventselec13_.type=?)) , event0_.id=633188 

but has be

where (event0_.time>=? or (event0_.time>=? , (eventselec13_.type=? or eventselec13_.type=?)) or (event0_.endtime>=? , (eventselec13_.type=? or eventselec13_.type=? or eventselec13_.type=?))) , event0_.id=633188 

it still isn't want , cant seem work way want to.

start obvious, first problem:

event.time >= '$clubhours' && (`eventselecttype`.`type`='cafe' || `eventselecttype`.`type`='dj'))  

this should constructed

cb.and(     cb.greaterthanorequalto(eventroot.<date>get("time"), cal.gettime()),      cb.or(         cb.equal(eventtype.<string>get("type"), "cafe"),         cb.equal(eventtype.<string>get("type"), "dj")     ) ), ... 

instead have:

cb.and(     cb.greaterthanorequalto(eventroot.<date>get("time"), cal.gettime()) ), cb.or(     cb.equal(eventtype.<string>get("type"), "cafe"),     cb.equal(eventtype.<string>get("type"), "dj") ) 

so, basically, need sure @ parentheses , not indenting in order understand code doing. side note, better off constructing predicate in steps code easier read , understand. e.g.:

predicate eventtypeiscafeordj = cb.or(     cb.equal(eventtype.<string>get("type"), "cafe"),     cb.equal(eventtype.<string>get("type"), "dj") ); predicate timegreaterorequalto = cb.greaterthanorequalto(eventroot.<date>get("time"), cal.gettime()); eqr.where( cb.and( timegreaterorequalto, eventtypeiscafeordj ) ); 

the database slower part of code , optimizer make same runtime out or either set of code, should make easier on , others. further, time tested way of debugging coding problem, when see parens.
