Code からの接続
CData ADO.NET Provider for SAP HANA は、SAPHANAConnection に標準DbConnection オブジェクトを実装しています。SAPHANAConnectionStringBuilder を使用して、プログラムで接続文字列をビルド、パース、およびリビルドすることもできます。
Connection オブジェクトの作成
接続文字列の定義と認証については、接続の確立 を参照してください。SAPHANAConnection オブジェクトを作成する一般的な呼び出しは以下のとおりです。
C#
using (SAPHANAConnection connection =
new SAPHANAConnection("User=system;Password=mypassword;Server=localhost;Database=systemdb;"))
{
connection.Open();
}
VB.NET
Using connection As New SAPHANAConnection("User=system;Password=mypassword;Server=localhost;Database=systemdb;")
connection.Open
End Using
SAPHANAConnectionStringBuilder の使用
次のコード例は、ADO.NET 接続文字列ビルダーを使用して接続文字列をパースする方法を示します。
C#
SAPHANAConnectionStringBuilder builder =
new SAPHANAConnectionStringBuilder("User=system;Password=mypassword;Server=localhost;Database=systemdb;");
//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 = "User=system;Password=mypassword;Server=localhost;Database=systemdb;";
//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 SAPHANAConnectionStringBuilder = New SAPHANAConnectionStringBuilder("User=system;Password=mypassword;Server=localhost;Database=systemdb;")
'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 = User=system;Password=mypassword;Server=localhost;Database=systemdb;"
'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
