Forms - Fetch

Retrieve Gravity Forms using SQL Server

Prerequisites:

See SQLHTTP easy setup for Gravity Forms
See API Call documentation for parameter values and other information
Create the stored procedure documented below

Stored Procedure:


CREATE PROCEDURE usp_GravityForms_Forms_Fetch(
		@Profile nvarchar(100),
		@Response nvarchar(MAX) OUTPUT,
		@StatusCode int OUTPUT,
		@StatusDescription nvarchar(MAX) OUTPUT)
AS

DECLARE @URL nvarchar(MAX) 
DECLARE @QueryString nvarchar(MAX)
DECLARE @HTTPSessionID uniqueidentifier

DECLARE @Path nvarchar(MAX) 
DECLARE @PublicKey nvarchar(100)
DECLARE @UNIXTime bigint
DECLARE @Signature varchar(100)

SET @URL = SQLHTTP.net.AuthParam(@Profile, 'RootURL')

SET @Path = N'forms' COLLATE SQL_Latin1_General_CP1_CI_AS

EXEC usp_GravityForms_AuthParameters	@Profile = @Profile,
					@Method = 'GET',
					@Path = @Path,
					@PublicKey = @PublicKey OUTPUT,
					@UNIXTime = @UNIXTime OUTPUT,
					@Signature = @Signature OUTPUT

SET @URL = @URL 
	+ N'/gravityformsapi/' COLLATE SQL_Latin1_General_CP1_CI_AS
	+ @Path

EXEC SQLHTTP.net.QueryStringBuilder @QueryString OUTPUT,
				    @Profile, 
				    'api_key', @PublicKey,
				    'expires', @UNIXTime

SET @URL = @URL + @QueryString 
		+ '&signature=' COLLATE SQL_Latin1_General_CP1_CI_AS
		+ @Signature

EXEC SQLHTTP.net.HttpSession @HttpSessionID OUTPUT

EXEC SQLHTTP.net.HttpRequest    @HttpSessionID,
				@URL = @URL,
				@AllowAutoRedirect = 1,
				@Response = @Response OUTPUT,
				@StatusCode = @StatusCode OUTPUT,
				@StatusDescription = @StatusDescription OUTPUT
GO

CREATE PROCEDURE usp_GravityForms_Forms_Fetch(

@Profile nvarchar(100),

@Response nvarchar(MAX) OUTPUT,

@StatusCode int OUTPUT,

@StatusDescription nvarchar(MAX) OUTPUT)

DECLARE @URL nvarchar(MAX)

DECLARE @QueryString nvarchar(MAX)

DECLARE @HTTPSessionID uniqueidentifier

DECLARE @Path nvarchar(MAX)

DECLARE @PublicKey nvarchar(100)

DECLARE @UNIXTime bigint

DECLARE @Signature varchar(100)

SET @URL = SQLHTTP.net.AuthParam(@Profile, 'RootURL')

SET @Path = N'forms' COLLATE SQL_Latin1_General_CP1_CI_AS

EXEC SQLHTTP.net.HttpSession @HttpSessionID OUTPUT

EXEC SQLHTTP.net.HttpRequest @HttpSessionID,

@URL = @URL,

@AllowAutoRedirect = 1,

@Response = @Response OUTPUT,

@StatusCode = @StatusCode OUTPUT,

Sample Usage:


DECLARE @Response nvarchar(MAX)
DECLARE @StatusCode int
DECLARE @StatusDescription nvarchar(MAX)

EXEC usp_GravityForms_Forms_Fetch 
		@Profile = 'My GravityForms',
		@Response = @Response OUTPUT, 
		@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')

		WHILE EXISTS(	SELECT *
				FROM SQLHTTP.net.MidTexts(CONVERT(nvarchar(MAX), @X), '_x', '_'))
		BEGIN
			SET @X = CONVERT(xml,
			REPLACE(CONVERT(nvarchar(MAX), @X),
			'_x' 
			+ SQLHTTP.net.MidText(CONVERT(nvarchar(MAX), @X), '_x', '_', 1)
			+ '_',
			'Form'))
		END

		----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/response/Form' --

		SELECT T.C.value(N'@id', N'nvarchar(MAX)') AS id
		      ,T.C.value(N'@entries', N'nvarchar(MAX)') AS entries
		      ,T.C.value(N'@title', N'nvarchar(MAX)') AS title
		FROM @X.nodes(N'/JsonObject/response/Form') T(C)

	END

DECLARE @Response nvarchar(MAX)

DECLARE @StatusCode int

DECLARE @StatusDescription nvarchar(MAX)

EXEC usp_GravityForms_Forms_Fetch

@Profile = 'My GravityForms',

@Response = @Response OUTPUT,

@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')

WHILE EXISTS( SELECT *

BEGIN

SET @X = CONVERT(xml,

REPLACE(CONVERT(nvarchar(MAX), @X),

'_x'

+ SQLHTTP.net.MidText(CONVERT(nvarchar(MAX), @X), '_x', '_', 1)

+ '_',
