Error when calling SQL SP via LINQ
- by PaulC
Newbie problem: I have a SQL SP with ten parameters (eight input, two output) but when I attempt to call it via LINQ from code I get the following error message:
"The best overloaded method match for 'DataClassesDataContext.ST_CR_CREATE_CASE_BASIS(string, string, string, string, System.DateTime?, string, string, string, ref int?, ref int?)' has some invalid arguments".
The params with ? appear to be unrecognized, but I'm baffled: the data types match the SQL types, the number of parameters match, the other parmeters don't exhibit the same behaviour. Can anyone tell me what's going on? Thanks in advance.
-- SQL SP:
create procedure ST_CR_CREATE_CASE_BASIS
@p_Pers_No nvarchar (50),
@p_Subject nvarchar (255),
@p_RQ_XML nvarchar(max),
@p_RQ_XSL nvarchar(max),
@p_Date_Submit smalldatetime,
@p_User_ID_Submit nvarchar (255),
@p_RQ_Status nvarchar (50),
@p_User_ID_OnBehalf nvarchar (255),
@p_Case_Number int output,
@p_RQ_ID int output
as
begin
-- ... etc.; the SP works fine when called from SSMS
The code-behind proc from the aspx page looks like this:
protected void cmdSubmit_Click(object sender, EventArgs e)
{
using (DataClassesDataContext vDataCont = new DataClassesDataContext())
{
Int32 vNewCaseNr;
Int32 vNewReqNr;
DateTime vNow = System.DateTime.Now;
vDataCont.ST_CR_CREATE_CASE_BASIS("101", "Test Subject Late Wed", null, null, vNow , "101", "1", "101", ref vNewCaseNr, vNewReqNr);
}
}
