spring-boot – 如何在SpringBoot Cassandra的where子句中使用IN运算符

2019年7月28日 194次阅读

我试图从
SpringBoot存储库运行以下查询

@Query("select * from c where id1 =?0 and id2 =?1 and id3 =?2 and c1 =?3 and year in :year and month in :month and day in :day and hour in :hour and minute in :minute"
public List<Counter> findCWithinRangeIn(
    @Param("id1") String id1,
    @Param("id2") String id2,
    @Param("id3") String id3,
    @Param("c1") String c1,
    @Param("year") List<Integer> year,
    @Param("month") List<Integer> month,
    @Param("day") List<Integer> day, 
    @Param("hour") List<Integer> hour,
    @Param("minute") List<Integer> minute);

但总是遇到错误：绑定变量的数量无效.

请建议如何进一步.

注意：我确实遵循了Spring CrudRepository findByInventoryIds(List<Long> inventoryIdList) – equivalent to IN clause,但它对我不起作用.

我想执行类似的事情：

select * from c
where id1 ="xyz" and 
      id2 ="abc" and 
      id3 ="pqr" and 
      c1 = "Sample" and
      year IN (2016,2017) and
      month IN (9,10,11) and
      day IN (19,20,24) and
      hour IN (23, 13) and
      minute IN (50, 51, 53)

最佳答案 如果您不需要指定自定义查询,这可能适合您(基于方法名称)

public List<Counter> findAllById1AndId2AndId3AndC1AndYearInAndMonthInAndDayInAndHourInAndMinuteIn(String id1, STring id2, String id3, String c1, List<Long> years, List<Long> months, List<Long> days, List<Long> hours, List<Long> minutes)

注意：在Counter实体中,字段的名称必须与方法名称中指定的属性名称相匹配.
