ストアドプロシージャの呼び出し
他のSQL ストアドプロシージャと同様に、SAPBusinessObjectsBICommand を使用してストアドプロシージャを呼び出すことができます。SAPBusinessObjectsBICommand オブジェクトをインスタンス化するには、コンストラクタへの引数として、ストアドプロシージャの名前とSAPBusinessObjectsBIConnection インスタンスを渡します。CommandType プロパティをStoredProcedure に設定し、SAPBusinessObjectsBICommand インスタンスのParameters コレクションにキーと値のペアとしてパラメータを追加します。
C#
string connectionString = "User=MyUser;Password=MyPassword;Url=http://myserver:6405/biprws;"; using (SAPBusinessObjectsBIConnection connection = new SAPBusinessObjectsBIConnection(connectionString)) { SAPBusinessObjectsBICommand cmd = new SAPBusinessObjectsBICommand("SampleProcedure", connection); cmd.CommandType = CommandType.StoredProcedure; cmd.Parameters.Add(new SAPBusinessObjectsBIParameter("@Id", "7")); // Add other parameters as needed ... SAPBusinessObjectsBIDataReader rdr = cmd.ExecuteReader(); while (rdr.Read()) { for (int i = 0; i < rdr.FieldCount; i++) { Console.WriteLine(rdr.GetName(i) + " --> " + rdr[i]); } Console.WriteLine(); } }
VB.NET
Dim connectionString As String = "User=MyUser;Password=MyPassword;Url=http://myserver:6405/biprws;" Using connection As New SAPBusinessObjectsBIConnection(connectionString) Dim cmd As New SAPBusinessObjectsBICommand("SampleProcedure", connection) cmd.CommandType = CommandType.StoredProcedure cmd.Parameters.Add(New SAPBusinessObjectsBIParameter("@Id", "7")) ' Add other parameters as needed ... Dim rdr As SAPBusinessObjectsBIDataReader = cmd.ExecuteReader() While rdr.Read() For i As Integer = 0 To rdr.FieldCount - 1 Console.WriteLine(rdr.GetName(i) + " --> " + rdr(i)) Next Console.WriteLine() End While End Using
別の方法として、ストアドプロシージャのパラメータをコマンドのテキストとして設定することもできます。ストアドプロシージャのステートメントは、次の標準的な形式でサポートされます。
"EXECUTE my_proc @first = 1, @second = 2, @third = 3;" "EXEC my_proc @first = 1, @second = 2, @third = 3;"
パラメータ化されたクエリを実行するには、SAPBusinessObjectsBICommand インスタンスのParameters コレクションに、キーと値のペアとしてパラメータを追加します。
C#
string connectionString = "User=MyUser;Password=MyPassword;Url=http://myserver:6405/biprws;"; using (SAPBusinessObjectsBIConnection connection = new SAPBusinessObjectsBIConnection(connectionString)) { SAPBusinessObjectsBICommand cmd = new SAPBusinessObjectsBICommand("EXECUTE SampleProcedure Id = @Id;", connection); cmd.Parameters.Add(new SAPBusinessObjectsBIParameter("@Id", "7")); // Add other parameters as needed ... SAPBusinessObjectsBIDataReader rdr = cmd.ExecuteReader(); while (rdr.Read()) { for (int i = 0; i < rdr.FieldCount; i++) { Console.WriteLine(rdr.GetName(i) + " --> " + rdr[i]); } Console.WriteLine(); } }
VB.NET
Dim connectionString As String = "User=MyUser;Password=MyPassword;Url=http://myserver:6405/biprws;" Using connection As New SAPBusinessObjectsBIConnection(connectionString) Dim cmd As New SAPBusinessObjectsBICommand("EXECUTE SampleProcedure Id = @Id;", connection) cmd.Parameters.Add(New SAPBusinessObjectsBIParameter("@Id", "7")) ' Add other parameters as needed ... Dim rdr As SAPBusinessObjectsBIDataReader = cmd.ExecuteReader() While rdr.Read() For i As Integer = 0 To rdr.FieldCount - 1 Console.WriteLine(rdr.GetName(i) + " --> " + rdr(i)) Next Console.WriteLine() End While End Using
