Telerik Reporting でユーザー パラメータとして使用したいので、SQL を使用して UserID に基づいて aspnet_profile テーブルからユーザーの FirstName と LastName を取得する方法を教えてください。

サンプル行 (FirstName は George、LastName は 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:‌​

SQLの使用を主張する場合は、多数のSUBSTRINGとPATINDEXがそこに到達すると確信していますが、クリーンなソリューションにはなりません。

更新： user373721は素晴らしいリソースを見つけてコメントを投稿しましたが、見逃しやすいので、それも回答に追加することにしました-T-SQLを使用してMS SQLデータベースからasp.netプロファイル値を取得するにはどうすればよいですか？

組み込みのdbo.aspnet_Profile_GetPropertiesストアドプロシージャPropertyValuesStringは、後で関数で解析される値を返しますParseDataFromDB 。

private void GetPropertyValuesFromDatabase(string userName, SettingsPropertyValueCollection svc)
{
    if (HostingEnvironment.IsHosted && EtwTrace.IsTraceEnabled(4, 8))
    {
        EtwTrace.Trace(EtwTraceType.ETW_TYPE_PROFILE_BEGIN, HttpContext.Current.WorkerRequest);
    }
    HttpContext current = HttpContext.Current;
    string[] names = null;
    string values = null;
    byte[] buffer = null;
    if (current != null)
    {
        if (!current.Request.IsAuthenticated)
        {
            string anonymousID = current.Request.AnonymousID;
        }
        else
        {
            string name = current.User.Identity.Name;
        }
    }
    try
    {
        SqlConnectionHolder connection = null;
        SqlDataReader reader = null;
        try
        {
            connection = SqlConnectionHelper.GetConnection(this._sqlConnectionString, true);
            this.CheckSchemaVersion(connection.Connection);
            SqlCommand command = new SqlCommand("dbo.aspnet_Profile_GetProperties", connection.Connection) {
                CommandTimeout = this.CommandTimeout,
                CommandType = CommandType.StoredProcedure
            };
            command.Parameters.Add(this.CreateInputParam("@ApplicationName", SqlDbType.NVarChar, this.ApplicationName));
            command.Parameters.Add(this.CreateInputParam("@UserName", SqlDbType.NVarChar, userName));
            command.Parameters.Add(this.CreateInputParam("@CurrentTimeUtc", SqlDbType.DateTime, DateTime.UtcNow));
            reader = command.ExecuteReader(CommandBehavior.SingleRow);
            if (reader.Read())
            {
                names = reader.GetString(0).Split(new char[] { ':' });
                values = reader.GetString(1);
                int length = (int) reader.GetBytes(2, 0L, null, 0, 0);
                buffer = new byte[length];
                reader.GetBytes(2, 0L, buffer, 0, length);
            }
        }
        finally
        {
            if (connection != null)
            {
                connection.Close();
                connection = null;
            }
            if (reader != null)
            {
                reader.Close();
            }
        }
        ProfileModule.ParseDataFromDB(names, values, buffer, svc);
        if (HostingEnvironment.IsHosted && EtwTrace.IsTraceEnabled(4, 8))
        {
            EtwTrace.Trace(EtwTraceType.ETW_TYPE_PROFILE_END, HttpContext.Current.WorkerRequest, userName);
        }
    }
    catch
    {
        throw;
    }
}

  

internal static void ParseDataFromDB(string[] names, string values, byte[] buf, SettingsPropertyValueCollection properties)
{
    if (((names != null) && (values != null)) && ((buf != null) && (properties != null)))
    {
        try

            for (int i = 0; i < (names.Length / 4); i++)
            {

                SettingsPropertyValue value2 = properties[str];

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

これは私を大いに助けました！

そのリンクの手順に従うと、aspnet_profile テーブルから PropertyValueString の特定のデータを取得できました。

コピーと貼り付け - 最初の機能:

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

2 番目の機能:

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

SQL クエリはニーズに合わせて変更できます

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