Hi All,
Wrote in august to the support list but no answer:
https://groups.yahoo.com/neo/groups/firebird-support/conversations/topics/129585
So, I want to try the new API (looks more easier to use than the old)
but got an exception with the TPB:
invalid format for transaction parameter block
-wrong version of transaction parameter block
See the attached example. No exception if build and pass the TPB in an
"array of Byte" (see in the commented out code).
What I am doing wrong with IXpbBuilder?
Gabor
program FB3_OOAPI_TPB;
{$IFDEF FPC}
{$MODE DELPHI}
{$ENDIF}
uses Firebird;
var
master:IMaster;
dispatcher:IProvider;
attachment:IAttachment;
status:IStatus;
transaction_rw:ITransaction;
util:Firebird.IUtil;
s:ansistring;
tpb:IXpbBuilder;
// TPB:array of Byte;
DPB:IXpbBuilder;
begin
try
master:=fb_get_master_interface;
dispatcher:=master.getDispatcher;
status:=master.getStatus;
util:=master.getUtilInterface;
DPB:=util.getXpbBuilder(status,IXpbBuilder.DPB,nil,0);
DPB.insertString(status,isc_dpb_user_name,'SYSDBA');
DPB.insertString(status,isc_dpb_password,'masterkey');
attachment:=dispatcher.attachDatabase(status,'employee',DPB.getBufferLength(status),DPB.getBuffer(status));
tpb:=util.getXpbBuilder(status,IXpbBuilder.TPB,nil,0);
tpb.insertTag(status,isc_tpb_version3);
tpb.insertTag(status,isc_tpb_read_committed);
tpb.insertTag(status,isc_tpb_no_rec_version);
tpb.insertTag(status,isc_tpb_wait);
tpb.insertTag(status,isc_tpb_write);
transaction_rw:=attachment.startTransaction(status,tpb.getBufferLength(status),tpb.getBuffer(status));
(*
SetLength(TPB, 5);
TPB[0]:=isc_tpb_version3;
TPB[1]:=isc_tpb_read_committed;
TPB[2]:=isc_tpb_no_rec_version;
TPB[3]:=isc_tpb_wait;
TPB[4]:=isc_tpb_write;
transaction_rw:=attachment.startTransaction(status,Length(TPB),@TPB[0]);
*)
except
on e:FbException do
begin
SetLength(s,2000);
SetLength(s,util.formatStatus(PAnsiChar(s),2000,e.getStatus));
WriteLn('Exception: ',AnsiString(s));
end;
end;
