You can invoke a stored procedure using ZuoraCommand in the same way as any other SQL stored procedure. To instantiate a ZuoraCommand object, provide the name of the stored procedure and a ZuoraConnection instance as arguments to the constructor. Set the value of the CommandType property to "StoredProcedure" and add the parameters as key-value pairs to the Parameters collection of the ZuoraCommand instance.

C#

string connectionString = "InitiateOAuth=GETANDREFRESH;OAuthClientID=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;Tenant=USProduction;ZuoraService=DataQuery;";

using (ZuoraConnection connection = new ZuoraConnection(connectionString)) {
  ZuoraCommand cmd = new ZuoraCommand("SampleProcedure", connection);
  cmd.CommandType = CommandType.StoredProcedure; 
  cmd.Parameters.Add(new ZuoraParameter("@Id", "7"));
  // Add other parameters as needed ...

  ZuoraDataReader 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 = "InitiateOAuth=GETANDREFRESH;OAuthClientID=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;Tenant=USProduction;ZuoraService=DataQuery;"

Using connection As New ZuoraConnection(connectionString)
  Dim cmd As New ZuoraCommand("SampleProcedure", connection)
  cmd.CommandType = CommandType.StoredProcedure
  cmd.Parameters.Add(New ZuoraParameter("@Id", "7"))
  ' Add other parameters as needed ...

  Dim rdr As ZuoraDataReader = 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

Alternatively, you can set the parameters of a stored procedure in the text of the command. The support for stored procedure statements follows the standard form shown below:

"EXECUTE my_proc @first = 1, @second = 2, @third = 3;"

"EXEC my_proc @first = 1, @second = 2, @third = 3;"

To execute a parameterized query, add parameters as key-value pairs to the Parameters collection of the ZuoraCommand instance.

C#

string connectionString = "InitiateOAuth=GETANDREFRESH;OAuthClientID=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;Tenant=USProduction;ZuoraService=DataQuery;";

using (ZuoraConnection connection = new ZuoraConnection(connectionString)) {
  ZuoraCommand cmd = new ZuoraCommand("EXECUTE SampleProcedure Id = @Id;", connection); 
  cmd.Parameters.Add(new ZuoraParameter("@Id", "7"));
  // Add other parameters as needed ...

  ZuoraDataReader 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 = "InitiateOAuth=GETANDREFRESH;OAuthClientID=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;Tenant=USProduction;ZuoraService=DataQuery;"

Using connection As New ZuoraConnection(connectionString)
  Dim cmd As New ZuoraCommand("EXECUTE SampleProcedure Id = @Id;", connection)
  cmd.Parameters.Add(New ZuoraParameter("@Id", "7"))
  ' Add other parameters as needed ...

  Dim rdr As ZuoraDataReader = 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
