Connecting from Code

The CData ADO.NET Provider for SAP Ariba Procurement implements a standard DbConnection object in SAPAribaProcurementConnection. You can also use the SAPAribaProcurementConnectionStringBuilder to programmatically build, parse, and rebuild connection strings.

Creating Connection Objects

See Establishing a Connection for guides to defining the connection string and authenticating. Below is a typical invocation to create SAPAribaProcurementConnection objects.

using (SAPAribaProcurementConnection connection =   
  new SAPAribaProcurementConnection("ANID=AN02000000280;API=PurchaseOrdersBuyerAPI-V1;APIKey=wWVLn7WTAXrIRMAzZ6VnuEj7Ekot5jnU;AuthScheme=OAuthClient;InitiateOAuth=GETANDREFRESH;OAuthClientId=testClient;OAuthClientSecret=testClientSecret;UseSandbox=false;"))  
{  
  connection.Open();  
}

VB.NET

Using connection As New SAPAribaProcurementConnection("ANID=AN02000000280;API=PurchaseOrdersBuyerAPI-V1;APIKey=wWVLn7WTAXrIRMAzZ6VnuEj7Ekot5jnU;AuthScheme=OAuthClient;InitiateOAuth=GETANDREFRESH;OAuthClientId=testClient;OAuthClientSecret=testClientSecret;UseSandbox=false;")
  connection.Open
End Using

Using SAPAribaProcurementConnectionStringBuilder

The following code example shows how to use an ADO.NET connection string builder to parse a connection string.

SAPAribaProcurementConnectionStringBuilder builder =
  new SAPAribaProcurementConnectionStringBuilder("ANID=AN02000000280;API=PurchaseOrdersBuyerAPI-V1;APIKey=wWVLn7WTAXrIRMAzZ6VnuEj7Ekot5jnU;AuthScheme=OAuthClient;InitiateOAuth=GETANDREFRESH;OAuthClientId=testClient;OAuthClientSecret=testClientSecret;UseSandbox=false;");
  //Pass the connection string builder an existing connection string, and you can get and set any of the elements as strongly typed properties.
  builder.ConnectionString = "ANID=AN02000000280;API=PurchaseOrdersBuyerAPI-V1;APIKey=wWVLn7WTAXrIRMAzZ6VnuEj7Ekot5jnU;AuthScheme=OAuthClient;InitiateOAuth=GETANDREFRESH;OAuthClientId=testClient;OAuthClientSecret=testClientSecret;UseSandbox=false;";
  //Now that the connection string has been parsed,
  // you can work with individual items:
  builder.MyString = "new property";
  builder.MyBoolean = true;

  // You can refer to connection keys using strings, 
  // as well. 
  builder["Logfile"] = "test.log";
  builder["Verbosity"] = 5;

VB.NET

Dim builder As SAPAribaProcurementConnectionStringBuilder = New SAPAribaProcurementConnectionStringBuilder("ANID=AN02000000280;API=PurchaseOrdersBuyerAPI-V1;APIKey=wWVLn7WTAXrIRMAzZ6VnuEj7Ekot5jnU;AuthScheme=OAuthClient;InitiateOAuth=GETANDREFRESH;OAuthClientId=testClient;OAuthClientSecret=testClientSecret;UseSandbox=false;")
'Pass the connection string builder an existing connection string, and you can get and set any of the elements using strongly typed properties.
builder.ConnectionString = ANID=AN02000000280;API=PurchaseOrdersBuyerAPI-V1;APIKey=wWVLn7WTAXrIRMAzZ6VnuEj7Ekot5jnU;AuthScheme=OAuthClient;InitiateOAuth=GETANDREFRESH;OAuthClientId=testClient;OAuthClientSecret=testClientSecret;UseSandbox=false;"
'Now that the connection string has been parsed,
' you can work with individual items:
builder.MyString = "new property"
builder.MyBoolean = True
  
' You can refer to connection keys using strings, 
' as well. 
builder("Logfile") = "test.log"
builder("Verbosity") = 5
