我在数据库中有一个表，表中有租户的数量，每个租户列出了他们每个日期的销售记录。在某些情况下，承租人在特定日期没有销售额，因此表中没有打破正确日期顺序的记录。请参见下面的示例表以获取说明：

我在sql中使用这个select查询来显示上面的输出

select tenant, date, sales
from tblSales
where date between '01/01/2015' and '01/05/2014'

我需要的是一个正确的输出：根据where子句上选择的日期范围显示完成日期，当租户在特定日期没有记录时，查询应该在该特定租户中添加日期记录，只需在sales列中添加null值，如下图所示：

作为我最初的解决方案，我考虑创建一个临时表，根据选择的日期范围插入一个日期序列，并使用该序列与实际表左连接。以下是我的开始：

然后，我使用left join来显示缺少的日期，但这只会导致一个租户，并且它也会使租户名称为null。像这样：

如果您有任何建议，我们将不胜感激。

您可以使用

基本上，您可以使用理货表生成从@startDate到@endDate的日期序列，并将其交叉连接到不同的项目以生成所有日期项目组合。然后，结果将与tblSales合并，以获得所需的输出

这里有一个替代方案。使用sys.columns生成理货表，而不是级联CTE：

结果

你可以用一个简单的方法来做这件事

这里有一个替代方案。使用sys.columns生成理货表，而不是级联CTE：

结果

我爱我们的答案！已投票表决，并已将其保存以备将来参考。这里还有一个建议。在Crystal的SQL命令中使用此代码。左外连接到您的销售表。它很长。这很乏味。但是，如果你不是一个SQL专家，这就更容易理解了，因为SQL专家对我的描述很好：如果你找到了他的答案，并且它是有效的，那么就忽略这个解决方案

注意：from子句不提供任何功能，只是为了满足这样的SQL语句中有from子句的要求。如果TBLASTS是一个大表，考虑从您的数据库中使用一个数据较少的数据库，并且仍然将外部连接连接到TBLASTAL。

你的1似乎是可以接受的。你的1似乎是可以接受的。问题，SELECT 1 UNION ALL part是什么意思，它重复的次数是固定的吗？我建议你阅读问题中引用的文章。此外，这可能会有所帮助：我发现这很难理解，也很难在我的代码中实现，但仍在努力。有什么方法或替代方案吗？请参阅我的更新问题以及我已经开始的代码，也许你可以改进@wewesthemenacem，我的答案基本上与你想要完成的相同。仅此而已，我的方法是基于集合的，而你的方法是基于RBAR的。这比您的实现要快得多。我建议您阅读我引用的文章。问题，SELECT 1 UNION ALL part是什么意思，它重复的次数是固定的吗？我建议您阅读问题中引用的文章。此外，这可能会有所帮助：我发现这很难理解，也很难在我的代码中实现，但仍在努力。有什么方法或替代方案吗？请参阅我的更新问题以及我已经开始的代码，也许你可以改进@wewesthemenacem，我的答案基本上与你想要完成的相同。仅此而已，我的方法是基于集合的，而你的方法是基于RBAR的。这比您的实现要快得多。我建议您阅读我引用的文章。如果您需要当前月份以外的月份，我认为这是可能的，请将GETDATE替换为参数字段。是的，我已经理解@wewe的答案。谢谢你的努力，如果有其他人遇到和我一样的问题，你的答案肯定会有帮助。谢谢你

需要一个非当前月份的月份，在我思考这个问题时，我意识到很可能用参数字段替换GETDATE。是的，我已经理解@wewe的答案。谢谢你的努力，如果有其他人遇到和我一样的问题，你的答案肯定会有帮助。谢谢
