Niet omdat het een goed idee is, maar zodat niemand anders hoeft uit te zoeken hoe de vreselijke sp_OAxxx opgeslagen procedures moeten worden gebruikt...
Hier is een update van mijn oude HTTP-opgeslagen procedure om zowel WinHttp te gebruiken als die optie in te stellen. De eigenschap Option is een "geïndexeerde eigenschap", dus het is raar om deze aan te roepen met sp_OASetProperty.
create or alter procedure get_http @url varchar(2000)
as
begin
/*
exec get_http 'https://www.bing.com'
*/
declare @hr int;
declare @win int;
declare @errorMessage varchar(2000);
begin try
EXEC @hr=sp_OACreate 'WinHttp.WinHttpRequest.5.1',@win OUT
IF @hr <> 0
begin;
set @errorMessage = concat('sp_OACreate failed ', convert(varchar(20),cast(@hr as varbinary(4)),1));
throw 60000, @errorMessage, 1;
end;
EXEC @hr=sp_OAMethod @win, 'Open',NULL,'GET',@url,'false'
IF @hr <> 0
begin;
set @errorMessage = concat('Open failed ', convert(varchar(20),cast(@hr as varbinary(4)),1));
throw 60000, @errorMessage, 1;
end;
--Option is an indexed property, so newvalue = 2048 and index = 9
--sp_OASetProperty objecttoken , propertyname , newvalue [ , index... ]
EXEC @hr=sp_OASetProperty @win, 'Option', 2048, 9
IF @hr <> 0
begin;
set @errorMessage = concat('set Option failed ', convert(varchar(20),cast(@hr as varbinary(4)),1) );
throw 60000, @errorMessage, 1;
end;
EXEC @hr=sp_OAMethod @win,'Send'
IF @hr <> 0
begin;
set @errorMessage = concat('Send failed ', convert(varchar(20),cast(@hr as varbinary(4)),1));
throw 60000, @errorMessage, 1;
end;
declare @status int
EXEC @hr=sp_OAGetProperty @win,'Status', @status out
IF @hr <> 0
begin;
set @errorMessage = concat('get Status failed ', convert(varchar(20),cast(@hr as varbinary(4)),1));
throw 60000, @errorMessage, 1;
end;
if @status <> 200
begin;
set @errorMessage = concat('web request failed ', @status);
throw 60000, @errorMessage, 1;
end;
declare @response table(text nvarchar(max));
insert into @response(text)
EXEC @hr=sp_OAGetProperty @win,'ResponseText';
IF @hr <> 0
begin;
set @errorMessage = concat('get ResponseText failed ', convert(varchar(20),cast(@hr as varbinary(4)),1));
throw 60000, @errorMessage, 1;
end;
select *

EXEC @hr=sp_OADestroy @win
IF @hr <> 0 EXEC sp_OAGetErrorInfo @win;
end try
begin catch
declare @error varchar(200) = error_message()
declare @source varchar(200);
declare @description varchar(200);
declare @helpfile varchar(200);
declare @helpid int;
exec sp_OAGetErrorInfo @win, @source out, @description out, @helpfile out, @helpid out;
