hibernate - JPA CriteriaBuilder - Expression - -



hibernate - JPA CriteriaBuilder - Expression <List> -

i have simple criteriaquery pattern match simple search string against field entires in person entity... e.g searchstring decorated %searchstring%

//using metamodel expression<list<records>> records = root.get(person_.records); expression<string> param = builder.parameter(string.class); //pseudo code(i think need here) predicate mypred = records (any record.field searchstring) path<integer> status = root.get("status"); criteriaquery.where( builder.or( builder.like( root.<string>get("name"), searchstring ), builder.like( root.<string>get("second_name"), searchstring ) //pseuso code (i lean need check predicate here?) builder.like(mypredicate) ), builder.equal(status,value) );

the person object can contain many record objects. update query above include similar 'like' pattern match each applicable field (string) of each element of list of records. obtain records below:

//using metamodel expression<list<records>> records = root.get(person_.records); expression<string> param = builder.parameter(string.class);

i have updated code pseudocode of 'think' want.any help much appreciated.

as far can tell not possible using criteriaquery. need utilize sql query... here's how did it...
