SQL aspnet_profile

Question

任何想法如何使用SQL基于UserID从aspnet_profile表中获取用户FirstName和LastName因为我想在Telerik Reporting中用作用户参数。

示例行（FirstName是George，LastName是Test）：

UserID: 06b24b5c-9aa1-426e-b7e4-0771c5f85e85

PropertyName: MobilePhone:S:0:0:Initials:S:0:1:City:S:1:14:FirstName:S:15:6:PostalCode:S:21:7:‌​WorkPhone:S:28:12:LastName:S:40:5:Address1:S:45:17:Address2:S:62:0:Province:S:62:‌​2:Organization:S:64:4:ClinicId:S:68:1:Country:S:69:6:Fax:S:75:0:MSPNumber:S:75:0:‌​ 

PropertyValuesString: HEast HustonEASGeorgeT7D 1N8604-111-2222Test5555 Beddtvue AveDCHCNL2Canada

PropertyValuesBinary: <Binary data>

Answer 1

如果你坚持使用SQL，我相信很多SUBSTRING和PATINDEX会让你到那里，但它不是一个干净的解决方案。

Answer 2

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：

首先你需要一个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

现在解析ProfileData： 下面的过程是我在对特定数据进行大量测试后发现的最快的方法。我已经测试了一次解析完整的表，但是运行速度比使用下面的函数慢，并且使用CROSS APPLY一次解析一个用户。

所以要调用该函数，请使用类似：

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声明，和 3）insert语句将数据从PIVOT复制到返回表

这是功能，享受！

http://www.karpach.com/Get-asp-net-profile-value-MS-SQL-database-using-T-SQL.htm

这对我帮助很大！

按照该链接中的步骤，我可以从aspnet_profile表中获取PropertyValueString中的任何特定数据。

复制和粘贴 - 第一个功能：

CREATE FUNCTION dbo.fn_GetElement
(
@ord AS INT,
@str AS VARCHAR(8000),
@delim AS VARCHAR(1) )

RETURNS INT
AS
BEGIN
  -- If input is invalid, return null.
  IF @str IS NULL
      OR LEN(@str) = 0
      OR @ord IS NULL
      OR @ord < 1
      -- @ord > [is the] expression that calculates the number of elements.
      OR @ord > LEN(@str) - LEN(REPLACE(@str, @delim, '')) + 1
    RETURN NULL
  DECLARE @pos AS INT, @curord AS INT
  SELECT @pos = 1, @curord = 1
  -- Find next element's start position and increment index.
  WHILE @curord < @ord
    SELECT
      @pos    = CHARINDEX(@delim, @str, @pos) + 1,
      @curord = @curord + 1
  RETURN
  CAST(SUBSTRING(@str, @pos, CHARINDEX(@delim, @str + @delim, @pos) - @pos) AS INT)
END

第二功能：

CREATE FUNCTION dbo.fn_GetProfileElement
(
@fieldName AS NVARCHAR(100),
@fields AS NVARCHAR(4000),
@values AS NVARCHAR(4000))

RETURNS NVARCHAR(4000)
AS
BEGIN
  -- If input is invalid, return null.
  IF @fieldName IS NULL
      OR LEN(@fieldName) = 0
      OR @fields IS NULL
      OR LEN(@fields) = 0
      OR @values IS NULL
      OR LEN(@values) = 0

    RETURN NULL

-- locate FieldName in Fields
DECLARE @fieldNameToken AS NVARCHAR(20)
DECLARE @fieldNameStart AS INTEGER,
@valueStart AS INTEGER,
@valueLength AS INTEGER

-- Only handle string type fields (:S:)
SET @fieldNameStart = CHARINDEX(@fieldName + ':S',@Fields,0)

-- If field is not found, return null
IF @fieldNameStart = 0 RETURN NULL
SET @fieldNameStart = @fieldNameStart + LEN(@fieldName) + 3

-- Get the field token which I've defined as the start of the
-- field offset to the end of the length
SET @fieldNameToken = SUBSTRING(@Fields,@fieldNameStart,LEN(@Fields)-@fieldNameStart)

-- Get the values for the offset and length
SET @valueStart = dbo.fn_getelement(1,@fieldNameToken,':')
SET @valueLength = dbo.fn_getelement(2,@fieldNameToken,':')

-- Check for sane values, 0 length means the profile item was
-- stored, just no data
IF @valueLength = 0 RETURN ''

-- Return the string
RETURN SUBSTRING(@values, @valueStart+1, @valueLength)

END

可以根据需要修改SQL查询

SELECT dbo.fn_GetProfileElement('FirstName',PropertyNames,PropertyValuesString)
     , dbo.fn_GetProfileElement('LastName',PropertyNames,PropertyValuesString)
FROM aspnet_Profile
