		@screen_name varchar(500),
		@include_entities bit = 0,
		@Response nvarchar(MAX) OUTPUT,
		@StatusCode int OUTPUT,
		@StatusDescription nvarchar(MAX) OUTPUT)
AS

DECLARE @Text_include_entities varchar(5)

SET @Text_include_entities =

       WHEN @include_entities = 0 THEN 'false'
<span style="color: #ff0000">       ELSE 'true'
    END
 
DECLARE @URL nvarchar(MAX)
DECLARE @QueryString varchar(MAX)
DECLARE @HTTPSessionID uniqueidentifier

SET @URL = 'https://api.twitter.com/1.1/users/show.json'

EXEC SQLHTTP.net.QueryStringBuilder   @QueryString OUTPUT,
				      @Profile,
				      'user_id', @User_Id,
				      'screen_name', @screen_name,

	  	@StatusCode = @StatusCode OUTPUT, 
	 	@StatusDescription = @StatusDescription OUTPUT

IF @StatusCode >= 400
	EXEC SQLHTTP.net.RaiseHttpError @StatusCode, @StatusDescription, @Response
ELSE
	BEGIN

		DECLARE @X xml
		SET @X = SQLHTTP.net.Json_To_Xml(@Response, '0')

		--The XPath syntax below was easily generated by executing the following commands:
		--EXEC SQLHTTP.net.XQueryHelper @X
		--and then executing: 
		--EXEC SQLHTTP.net.XQueryHelper @X, 'JsonObject'

		SELECT T.C.value(N'@id', N'nvarchar(MAX)') AS [id]
		      ,T.C.value(N'@name', N'nvarchar(MAX)') AS [name]
		      ,T.C.value(N'@location', N'nvarchar(MAX)') AS [location]
		      ,T.C.value(N'@followers_count', N'nvarchar(MAX)') AS [followers_count]
		      ,T.C.value(N'@created_at', N'nvarchar(MAX)') AS [created_at]
		FROM @X.nodes(N'/JsonObject') T(C)

	END

DECLARE @Response nvarchar(MAX)

DECLARE @StatusCode int

DECLARE @StatusDescription nvarchar(MAX)

EXEC usp_Twitter_User_Fetch
