检查一列是否等于一个数字数组mysql

Question

如何检查此查询的 int 数组？我查询只是为了检查 inregistrari.ID_camera= 101 例如，我如何检查 inregistrari.ID_camera = 101, 501 ..

SELECT DISTINCT(ID_camera), tip_confort.nume_tip_confort,
       COALESCE(SUM(inregistrari.ID_camera = '101'),0) AS nr_pers_in_camera, 
       locatii.nume_locatie, camere.nr_persoane_max  
  FROM inregistrari 
NATURAL JOIN camere 
NATURAL JOIN tip_confort 
NATURAL JOIN locatii 
  WHERE camere.ID_tip_confort =3 AND ID_camera=101;

我的查询结果是：

想要的结果

您仍然没有提供locatii表的结构和示例数据，但我认为可以使用group by如下：

SELECT ID_camera, 
       tip_confort.nume_tip_confort,      
       Count(*) AS nr_pers_in_camera, 
       locatii.nume_locatie, 
       camere.nr_persoane_max  
  FROM inregistrari 
  NATURAL JOIN camere 
  NATURAL JOIN tip_confort 
  NATURAL JOIN locatii 
 WHERE camere.ID_tip_confort =3 
   AND ID_camera in (101,501)
 Group by ID_camera, 
          tip_confort.nume_tip_confort,
          locatii.nume_locatie,
          camere.nr_persoane_max
