I try to through this code

try
{
SqlCommand cmd = new SqlCommand("dbo.generate_loan_entry", connect);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@farmer_code", party_code.Text);
cmd.Parameters.AddWithValue("@ticket_no", ticket_no.Text);
cmd.Parameters.AddWithValue("@total_loan", adj_loan);
connect.Open();
cmd.ExecuteNonQuery();
connect.Close();
}
catch (Exception ex)
{
Response.Write("<script>alert('" + ex.Message + "')</script>");
}
finally
{ }

My procedure is

ALTER PROCEDURE [dbo].[generate_loan_entry](@farmer_cd nvarchar(6),
@ticket_no int,
@total_loan int)
-- Add the parameters for the stored procedure here
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from

WHERE ACCOUNT_CODE = @v_account_code
AND PARTY_CODE = @farmer_cd AND isnull(voc_auth_flag,'N') = 'N';
if (@vloan_deduct > 0.0 )
begin
select @vloan_amount = @vloan_amount - @vloan_deduct;
end ;
IF (@vloan_amount < isnull(@total_loan,0) - isnull(@vadj_loan,0))
begin
select @vdeducted_loan = @vloan_amount ;
end;
ELSE
begin

end;
FETCH NEXT FROM C1 INTO @v_account_code,@vloan_amount;
IF @vdeducted_loan > 0
begin
INSERT INTO CA_LOAN_DEDUCTION VALUES(
@ticket_no,@v_account_code,@farmer_cd,@vloan_amount,@vdeducted_loan,null,'N');
end;
set @vadj_loan = @vadj_loan + @vdeducted_loan;
end;
