ENTERA DEVELOPER SUPPORT
Frequently Asked Questions Invoking non-published RPCs using TEnteraProvider Question: I'm using Delphi Enterprise to connect to an Entera data server. The RPC's ConflictRPC, DeleteRPC, InsertRPC, SelectRPC and UpdateRPC can be invoked by using 'Invoke.<RPC Function>' (ie Invoke.SelectRPC()), but how do I invoke a RPC that is not published - for example sql_set_max_rows_<ServerName>? Answer: Currently there is no way to invoke such RPCs using TEnteraProvider's published properties/methods. However, there is a workaround that involves a bit of coding. The folowing example calls sql_set_max_rows_test where test = ServerName and EnteraConnection1 = name of my TEnteraConnection object. with TRPCFunction.Create(Self) do try Name := 'sql_set_max_rows_test'; //test is ServerName with Params.Add do begin DataType := dtInteger; ParamName := 'maxrows'; ParamType := ptInput; Value := 10; //number of rows to retrive at one time end; Invoke(EnteraConnection1,True); finally Free; end;
