Je l'ai résolu...
La requête doit ressembler à ceci :
@Query(
value = "SELECT * FROM \n" +
"(institution INNER JOIN user ON institution.user_id = user.id) \n" +
"LEFT JOIN \n" +
"(SELECT * FROM \n" +
"building_institutions \n" +
"WHERE building_id = :userId)\n" +
" AS reserved_institutions \n" +
"ON reserved_institutions.institutions_user_id = kits_nwt.institution.user_id \n" +
" where reserved_institutions.institutions_user_id IS null \n"
+ "ORDER BY ?#{#pageable}"
,
countQuery = "SELECT count(*) FROM \n" +
"(institution INNER JOIN user ON institution.user_id = user.id) \n" +
"LEFT JOIN \n" +
"(SELECT * FROM \n" +
"building_institutions \n" +
"WHERE building_id =:userId)\n" +
" AS reserved_institutions \n" +
"ON reserved_institutions.institutions_user_id = kits_nwt.institution.user_id \n" +
"where reserved_institutions.institutions_user_id IS null \n" +
"ORDER BY ?#{#pageable}",
nativeQuery = true)
Page<Institution> findPotentialInstitutionsByBuildingId(@Param("userId") Long userId, Pageable pageable);
J'obtenais l'erreur à la ligne 4 près de WHERE, lorsque ma requête ressemblait à ceci :
@Query(
value = "SELECT username, password, description, location, title, user_id FROM (institution INNER JOIN user ON institution.user_id = user.id) LEFT JOIN\n" +
"(SELECT * FROM building_institutions WHERE building_institutions.building_id = 1) AS reserved_institutions\n" +
"ON reserved_institutions.institutions_user_id = kits_nwt.institution.user_id\n" +
"WHERE reserved_institutions.institutions_user_id IS null ORDER BY ?#{#pageable}",
nativeQuery = true)
Page<Institution> findPotentialInstitutionsByBuildingId(Long userId, Pageable pageable);
et c'est parce que je n'ai pas ajouté le countQuery paramètre au @Query annotation.
Un grand merci à tous ceux qui ont essayé d'aider.
J'espère que j'épargnerai à quelqu'un d'autre de nombreuses heures de misère.
Acclamations! :)
