多个SQL查询条件

Question

是否有采用下列标准在Access查询的方法吗？

联合查询不提供所有三个标准

LName, FName 
Where (TourID=14XXX and Status=0) AND 
      (TourID=16XXX and Status=1) AND 
      (TourID=20XXX and Status=1)

只有返回结果，所有三个条件都为真

Answer 1

使用或代替AND

select LName, FName from tablename
Where (TourID=14XXX and Status=0) OR
      (TourID=16XXX and Status=1) OR
      (TourID=20XXX and Status=1)

Answer 2

我想你想的聚集：

SELECT LName, FName 
FROM t
WHERE (TourID=14XXX and Status=0) OR 
      (TourID=16XXX and Status=1) OR 
      (TourID=20XXX and Status=1)
GROUP BY LName, FName 
HAVING COUNT(*) = 3;

该COUNT(*)假设旅行团没有在原始表复制。

SELECT LName, FName 
FROM t
WHERE (TourID=14XXX and Status=0) OR 
      (TourID=16XXX and Status=1) OR 
      (TourID=20XXX and Status=1)
GROUP BY LName, FName 
HAVING SUM(IIF(TourID=14XXX AND Status=0, 1, 0)) > 0 AND
       SUM(IIF(TourID=16XXX and Status=1, 1, 0)) > 0 AND
       SUM(IIF(TourID=20XXX and Status=1, 1, 0)) > 0;
