Hi I have the following code to insert data into a db
int svcTypeID = Convert.ToInt32(comboBox1.SelectedValue);
String svcGuid = label2.Text;
int heartbeat = Convert.ToInt32(textBox1.Text);
String hostname = System.Net.Dns.GetHostName();
Guid gu = new Guid(svcGuid);
SqlConnection conn = new SqlConnection(@"Data Source=x\x;Initial Catalog=task_system;Integrated Security=True");
SqlCommand cmd = new SqlCommand("storedProc");
cmd.Connection = conn;
cmd.Parameters.AddWithValue("@guid", gu);
cmd.Parameters.AddWithValue("@id", svcTypeID);
cmd.Parameters.AddWithValue("@heartbeat", heartbeat);
cmd.Parameters.AddWithValue("@hostname", "'" + hostname + "'");
cmd.Parameters.Add(new SqlParameter()
{
ParameterName = "RETURN_VALUE",
Direction = ParameterDirection.ReturnValue
});
conn.Open();
cmd.ExecuteNonQuery();
However the data will not insert, the stored procedure that I am using works in SQL when I execute it, so not sure what the issue is. The parts of the stored procedure relevant are:
@guid uniqueidentifier,
@id int,
@heartbeat int,
@hostname nvarchar(MAX)
IF @@ROWCOUNT < 1
BEGIN
INSERT INTO [services]
(guid,
id,
started_ts,
last_contact_ts,
heartbeat,
hostname)
VALUES (@guid,
@id,
GETDATE(),
GETDATE(),
@heartbeat,
@hostname)
END
When I run my code in visual studio it tells me the procedure or function expects parameter @guid which was not supplied, any ideas why it isnt getting the values i'm passing?
