Rafael Santini commented on HHH-1615:
-------------------------------------
I also ran into this problem with SQL Server. With MySQL the same query works.
HQL:
select count(emprestimo.exemplar.obra), emprestimo.exemplar.obra from Emprestimo
emprestimo where emprestimo.data between ? and ? group by emprestimo.exemplar.obra order
by count(emprestimo.exemplar.obra) desc
SQL generated:
select count(exemplar1_.id_obra) as col_0_0_, exemplar1_.id_obra as col_1_0_, obra2_.id as
id157_, obra2_.mfn as mfn157_, obra2_.titulo as titulo157_, obra2_.localizacao as
localiza4_157_, obra2_.id_idioma as id5_157_, obra2_.id_tipo_obra as id6_157_,
obra2_.id_categoria_obra as id7_157_, obra2_.id_area_obra as id8_157_, obra2_.id_base as
id9_157_ from bs_emp_mov_emprestimo emprestimo0_, bs_emp_ace_exemplar exemplar1_,
bs_emp_ace_obra obra2_ where emprestimo0_.id_exemplar=exemplar1_.id and
exemplar1_.id_obra=obra2_.id and (emprestimo0_.data between ? and ?) group by
exemplar1_.id_obra order by count(exemplar1_.id_obra) desc
Error:
A coluna 'bs_emp_ace_obra.ID' é inválida na lista de seleção porque não está
contida em uma função agregada nem na cláusula GROUP BY.
GROUP BY entity does not work
