Answer 1

Try using this:

sql_cmd.Parameters.AddWithValue
("@Company_ID",**Guid.Parse**("00000000-0000-0000-0000-000000000000");

That will take a simple string rep. and turn it into a GUID obj.

Answer 2

Just cast it from a varchar.

DECLARE @return_value int

EXEC    @return_value = [dbo].[usp_ReserveBook]
        @userID = CONVERT(uniqueidentifier, 'AE019609-99E0-4EF5-85BB-AD90DC302E70'),
        @bookID = 7,
        @dateReserved = N'09/03/2009',
        @status = 1

SELECT  'Return Value' = @return_value

Answer 3

You simply need to QUOTE your GUID:

DECLARE @return_value int

EXEC    @return_value = [dbo].[usp_ReserveBook]
        @userID = 'AE019609-99E0-4EF5-85BB-AD90DC302E70',  
        @bookID = 7,
        @dateReserved = N'09/03/2009',
        @status = 1

SELECT  'Return Value' = @return_value

Answer 4

You need single quotes around your GUID....it's just a string to sql server.

You could try letting the sp generate the GUID with the sql function newid() ...sql server only i think.

And if you're pulling the GUID from another table, let the SP go get that GUID from that table.
