Here's an example. Other ways of declaring and using parameters are possible. This uses an array declaration to receive the results.
Jesse - using ODBC will be similar performance, maybe a shade slower as the query has to be interpreted. You'd also need a connection string/details in addition to what your code might be doing elsewhere.
There's also an SQL interface in the C# library, so to use the client object functions as well as sql statements in the same connection is possible. If someone asks a separate question about that I may post an example!
using System;
using ClearScada.Client; // This requires a Reference from the project to this dll
using System.Security;
namespace InsertHistoricData
{
class Program
{
static void Main()
{
string user = "s";
string pass = "s";
ClearScada.Client.Simple.Connection connection;
var node = new ClearScada.Client.ServerNode(ClearScada.Client.ConnectionType.Standard, "127.0.0.1", 5481);
connection = new ClearScada.Client.Simple.Connection("Utility");
connection.Connect(node);
var spassword = new System.Security.SecureString();
foreach (var c in pass) spassword.AppendChar(c);
connection.LogOn(user, spassword);
ClearScada.Client.Simple.DBObject PointObj = connection.GetObject("Test General.Test His Insert and Load.New Analog Point");
DateTime now = DateTime.UtcNow;
Object[] p1 = new Object[4];
p1[0] = 1;
p1[1] = 192;
p1[2] = now;
p1[3] = 1;
PointObj.Aggregates["Historic"].InvokeMethod("LoadDataValue", p1);
Object[] p2 = new Object[5];
p2[0] = now.AddSeconds(-1);
p2[1] = now.AddSeconds(1);
p2[2] = 0;
p2[3] = true;
p2[4] = "All";
object r = PointObj.Aggregates["Historic"].InvokeMethod("RawValue", p2);
Console.WriteLine(r);
Object[] p3 = new Object[6];
p3[0] = now.AddSeconds(-1);
p3[1] = now.AddSeconds(1);
p3[2] = 0;
p3[3] = 1;
p3[4] = true;
p3[5] = "All";
object [] k = (object [])PointObj.Aggregates["Historic"].InvokeMethod("RawValues", p3);
Console.WriteLine(k[0]);
Console.ReadKey();
}
}
}
.
