对于那些仍在寻找使用纯 SQL 解析 aspnet_Profile 表的方法的人。这是我使用的：
首先，您需要一个 Tally 表。如果您不知道这是什么，请阅读 Jeff Moden 的这篇文章：http ://www.sqlservercentral.com/articles/T-SQL/62867/
要生成计数表，请使用以下脚本：
SELECT TOP 11000 IDENTITY(INT,1,1) AS N INTO dbo.Tally FROM Master.dbo.SysColumns sc1, Master.dbo.SysColumns sc2
--===== Add a Primary Key to maximize performance
ALTER TABLE dbo.Tally ADD CONSTRAINT PK_Tally_N PRIMARY KEY CLUSTERED (N) WITH FILLFACTOR = 100
--===== Let the public use it
GRANT SELECT, REFERENCES ON dbo.Tally TO PUBLIC
现在开始解析 ProfileData：在对我的特定数据进行大量测试后，下面的过程是我发现的最快的方法。我已经测试过一次解析完整的表，但是运行速度比使用下面的函数和使用 CROSS APPLY 一次解析一个用户要慢。
因此，要调用该函数，请使用以下内容：
SELECT bla, bla
FROM aspnet_Users u CROSS APPY dbo.ProfileProperties(u.UserID)
您唯一需要做的就是更新 3 件事以包含您使用的配置文件属性：1) 返回表 2) PIVOT 语句，以及 3) 将数据从 PIVOT 复制到返回表的插入语句
这是功能，享受！
