Connecting from Code

The CData ADO.NET Provider for SAP ERP implements a standard DbConnection object in SAPERPConnection. You can also use the SAPERPConnectionStringBuilder 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 SAPERPConnection objects.

using (SAPERPConnection connection =   
  new SAPERPConnection("Host=sap.mydomain.com;User=EXT90033;Password=xxx;Client=800;System Number=09;ConnectionType=Classic;"))  
{  
  connection.Open();  
}

VB.NET

Using connection As New SAPERPConnection("Host=sap.mydomain.com;User=EXT90033;Password=xxx;Client=800;System Number=09;ConnectionType=Classic;")
  connection.Open
End Using

Using SAPERPConnectionStringBuilder

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

SAPERPConnectionStringBuilder builder =
  new SAPERPConnectionStringBuilder("Host=sap.mydomain.com;User=EXT90033;Password=xxx;Client=800;System Number=09;ConnectionType=Classic;");
  //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 = "Host=sap.mydomain.com;User=EXT90033;Password=xxx;Client=800;System Number=09;ConnectionType=Classic;";
  //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 SAPERPConnectionStringBuilder = New SAPERPConnectionStringBuilder("Host=sap.mydomain.com;User=EXT90033;Password=xxx;Client=800;System Number=09;ConnectionType=Classic;")
'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 = Host=sap.mydomain.com;User=EXT90033;Password=xxx;Client=800;System Number=09;ConnectionType=Classic;"
'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
