我想在Oracle SQL Developer中执行此查询,以便测试并稍后在Java
中实现相同的查询。
SELECT
enti.*
FROM
Entity enti
WHERE
enti.apellidouno LIKE CONCAT('%',:apellido1,'%')
AND enti.nombreuno LIKE CONCAT('%',:nombre1,'%')
AND ( :apellido2 IS NULL OR enti.apellidodos LIKE CONCAT('%',:apellido2,'%') )
AND ( :nombre2 IS NULL OR enti.nombredos LIKE CONCAT('%',:nombre2,'%') );
我收到此消息
ORA-00909:不存在任何争议
00909. 00000-“参数数量无效”
*原因:
*行动:
错误,错误:103,列:30
此位置只是行中C
子句的字母CONCAT
:
enti.apellidouno LIKE
CONCAT
('%',:apellido1,'%')
现在,在我的界面中
public interface EntityRepository extends CrudRepository<Entity, Long>, JpaRepository<Entity, Long> {
public static final String ENTITY_POR_APELLIDOS_Y_NOMBRES
= " SELECT enti "
+ " FROM Entity enti "
+ " WHERE "
+ " enti.apellidouno LIKE CONCAT('%',:apellido1,'%') "
+ " AND enti.nombreuno LIKE CONCAT('%',:nombre1,'%') "
+ " AND (:apellido2 is null OR enti.apellidodos LIKE CONCAT('%',:apellido2,'%') "
+ " AND (:nombre2 is null OR enti.nombredos LIKE CONCAT('%',:nombre2,'%') ";
@Query(ENTITY_POR_APELLIDOS_Y_NOMBRES)
List<Entity> findEntityByApellidosAndNombres(
@Param("apellido1") String apellido1, @Param("apellido2") String apellido2,
@Param("nombre1") String nombre1, @Param("nombre2") String nombre2);
}
在Java中,我得到了:
Caused by: java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException:
unexpected token: null near line 1, column 353
[ SELECT enti FROM package.Entity enti
WHERE enti.apellidouno LIKE CONCAT('%',:apellido1,'%')
AND enti.nombreuno LIKE CONCAT('%',:nombre1,'%')
AND (:apellido2 is null OR enti.apellidodos LIKE CONCAT('%',:apellido2,'%')
AND (:nombre2 is null OR enti.nombredos LIKE CONCAT('%',:nombre2,'%') ]
答案 0 :(得分:1)
您需要嵌套CONCAT
,因为在Oracle中它仅处理2个参数:
SELECT enti.*
FROM Entity enti
WHERE enti.apellidouno LIKE CONCAT(CONCAT('%',:apellido1),'%')
-- ...
您可以选择使用||
:
SELECT enti.*
FROM Entity enti
WHERE enti.apellidouno LIKE '%' || :apellido1 || '%'
