jpa - How to count all rows returned from a JPASubQuery query via QueryDSL? -

-

my subquery returns list of servicetypeids , respective counts in table called 'billingdata'.

i perform count(*) operation on subqueryresult

jpasubquery subquery = new jpasubquery(); subquery.from(billingdata); subquery.where(         billingdata.servicetypeid.in(servicetype.type_one.getid(), servicetype.type_one_two.getid())                 .and(billingdata.accountid.isnull())                 .and(billingdata.price.isnotnull())                 .and(billingdata.numberid.eq(numbers.id)));//join condition subquery.groupby(billingdata.servicetypeid); subquery.having(billingdata.count().goe(1));

my count attempt 

            subquery             .list(billingdata.servicetypeid, billingdata.servicetypeid.count())             .count().eq(2l);

fails error

java.lang.illegalargumentexception: org.hibernate.hql.internal.ast.querysyntaxexception: expecting close, found ','

the error occurs when don't specify count.

i perform simple count(*), failing find way how extract column name subquery count parameter.

really stuck here :/

the following count expressions work

subquery.list(billingdata.servicetypeid).count().eq(2l);  subquery.count().eq(2l);  subquery.unique(billingdata.servicetypeid.count()).eq(2l);

count multiple columns not supported jpql
