内部选择
CASE WHEN VAL0 IN (SELECT * FROM tblDraw) THEN 1 ELSE 0 END
需要只返回一列。目前它正在返回所有列dbo.tblDraw。
唯一可以在子查询中使用 aSELECT * FROM的时候是子查询是EXISTS(SELECT * FROM...)查询时。
更新：
您的问题是由您的表格设计引起的。如果您有一个用于抽奖事件的表和另一个表，其中每个选择的号码包含一行，并且在客户端有类似的布局，那么您将遵循第 3 范式并且查询变得更加简单。但是，让我们假设您无法更改表架构。我还假设您使用的是 SQL 2008 或更高版本，因为我的解决方案不适用于 2005 或更早版本。
要获得您正在寻找的结果，您基本上需要取消旋转绘制值以及客户选择值。比您只需加入结果集并计算您返回的行数。假设所有值都是唯一的（通常是彩票中的情况），这将为您提供客户针对彩票抽奖所做的正确选择的数量。
我在下面发布了一个示例解决方案。不要对所有代码感到震惊。其中大部分是创建表并将一些随机值放入其中。只有查询 1标题之后的查询才是您要查找的内容。
我在创建对象时冒昧地更改了名称。我还稍微改变了一些数字，以使比赛更有可能发生。我的示例中的彩票是 15 次彩票中的 6 次。但这仅与示例数据创建有关，与最终查询无关。
该查询首先将 dbo.LottoDraws 表与 dbo.CustomerSelections 表连接起来。然后 id 交叉应用于子查询。该子查询使用VALUE运算符首先对客户选择的值进行反透视，然后对 LotteryDraws 进行反透视。然后它将这两个结果集连接在一起并计算匹配项。
