SQL Server 的自定义排序函数

2021-09-15 00:00:00 sorting user-defined-functions sql-server

我在 SQL Server 2005 中有一个列，它将版本号存储为我想要排序的字符串.我一直无法找到如何对此列进行排序，尽管我猜它是某种自定义函数或比较算法.

I have a column in SQL Server 2005 that stores a version number as a string that i would like to sort by. I have been unable to find out how to sort this column, although i am guessing it would be some kind of custom function or compare algorithm.

任何人都可以指出我从哪里开始的正确方向吗?我可能在谷歌上搜索错误的东西.

Can anyone point me in the right direction of where to start? I may be googling the wrong stuff.

干杯

推荐答案

我会使用单独的 int 列(例如，如果您正在跟踪主要 + 次要版本，则使用 MajorCol + MinorCol)并运行类似

I'd use separate int columns (e.g. MajorCol + MinorCol if you are tracking major + minor versions) and run something like

order by MajorCol, MinorCol

在我的查询中.
