Sql server 2008 SQL Server订单描述和显示6/6,sql-server-2008,Sql Server 2008,我在一个名为col1、col2、col3的表中有3列，其中包含整数值。有4000多行。有三个参数@first、@second、@third。我想根据此参数获取具有匹配项的行。该查询给出了结果，但没有给出3/3，或者如果没有匹配项，则不会显示，并且我希望将其降序排列。我的输出应该是这样的 table : col1 col2 col3 3 4 5 1 2 2 7 7 9 3 2 3 1 8 9 1

编辑-动态SQL解决方案：

下面是一个动态SQL解决方案，它将处理任意数量的列

但是请注意，动态SQL可能不是解决此问题的最佳解决方案，特别是当它将重复多次和/或在非常大的数据集上运行时。然而，这是我所知道的实现这一点的唯一方法，所以我想将其包括在内（并且非常高兴看到其他用户提供更好的解决方案！）

这没有帮助，请用您的预期结果和实际结果更新您的问题。请查看此链接（）以了解如何构建一个好问题。如果有6列，我将重复此查询六次。那么您有3列（根据您的问题），还是6列？你是说列数是可变的吗？如果是这样，你应该在问题中说明这一点。如果您愿意，我上面给出的解决方案可以很容易地为任意数量的静态列重写。如果您的列数是可变的，我们将不得不采取稍微复杂一点的方法。谢谢您的回复。目前calomn可能会注意到最多有3列6Ok，所以总共有3到6列之间的可变列数？如果是这样的话，你真的应该把这个添加到你的问题中，以避免得到毫无帮助的答案。谢谢你的友好回复。目前共有3列，列数最多可能变化6秒您的答案是给出结果水平形式我希望结果是垂直形式，如3/3 1 2/3 1/3 2 0/3 6

@first = 1
@second = 2
@third = 3
