Re: Zoes7.2 upgrade

Daniel,

could you debug function ZDbcInterbaseUtils.pas function procedure TZParamsSQLDA.UpdatePAnsiChar(const Index: Integer; const Value: PAnsiChar; const Len: Cardinal);

which field type is determined by ISC and are my conversion function correctly (you'll see this in if function UpdateDateTime(Index, TempTimeStamp); is called).

What i see is a minor bug with my last commit, ReadFormatSettings should be replaced by WriteFormatSettings. But AFAIK should they be binary equal for mORMot.

Re: Zoes7.2 upgrade

Now I have it:

My request calls

(2328) TempTimeStamp := RawSQLTimeToDateTime(Value, Len, ConSettings^.ReadFormatSettings, Failed);
After that TempTimeStamp is '30.12.1899' and thats the problem.

He looks for a time, but there is only a Date (the Type he found is SQL_TIMESTAMP).

If I do a my request so:

http://localhost:8180/root/?sql=select+RowID,*+from+kontoauszug+where+BTAG>'2014-01-01 00:00:00'+limit+10

then it works.

If you need futher information please let me know.

Re: Zoes7.2 upgrade

Thanx Daniel.

Arnaud today i commit my own idea about Batch insertiation with FireBird. see http://sourceforge.net/p/zeoslib/code-0/commit_browser R3275 \testing-7.2.

I added two size checks (correct me if i'm wrong): command should fit in 32KB range and whole allocated mem must fit in 64KB limit per execution.
Enabled SupportsArrayBindings indicator for Firebird in R3276.

Nice NO changes required in you framework!

I don't use fb-embedded(should perform much better) here, tested with FBCLIENT.DLL:

{
  "Engine": "ZEOS Firebird",
  "CreateTableTime": "137.45ms",
  "NumberOfElements": 5000,
  "InsertTime": "3.72s",
  "InsertRate": 1342,
  "InsertBatchTime": "122.62ms",
  "InsertBatchRate": 40776,
  "InsertTransactionTime": "354.58ms",
  "InsertTransactionRate": 14101,
  "InsertBatchTransactionTime": "123.99ms",
  "InsertBatchTransactionRate": 40323,
  "ReadOneByOneTime": "548.43ms",
  "ReadOneByOneRate": 9116,
  "ReadAllVirtualTime": "43.60ms",
  "ReadAllVirtualRate": 114676,
  "ReadAllDirectTime": "33.96ms",
  "ReadAllDirectRate": 147210,
  "ClientCloseTime": "4.82ms"
}

As i wrote: have no other component to compare the performance. Feel free to test the results smile I would be interested to know how we pereform agains Uni/FireDac now.

OpenSource rocks! Yes it does!

I wonder why my implementation is more than 20% faster than your initial version.
Sounds just like a small refactoring from your initial patch.

No idea the changes are not related to the results. It looks to me if my system falls into standby mode and wakes up then... OCI is still tired than wink

Re: Zoes7.2 upgrade

Great addition!

Resulting performance  boost is impressive.
Now FireDAC has no advantage over ZDBC when inserting such statements.
And all DB.pas / TDataSet based libraries (like FireDAC or UniDAC) are actually slower than ZDBC direct access, since TDataSet is a true bottleneck!

Thanks a lot for sharing!

@Arnaud

Could you add to the "30 - MVC Server" connection for ZEOS?.

Re: Zoes7.2 upgrade

@EgonHugeist

Now direct Zeos/ZDBC access is clearly the fastest way of using external SQL databases with mORMot.
For both writing and reading - and especially at reading, where by-passing DB.pas and its TDataSet bottleneck makes ZDBC 2.5 times faster than the expensive FireDAC!

Re: Zoes7.2 upgrade

Thanks Arnaud!

i was thinking about updating this link: http://blog.synopse.info/post/2013/11/0 … ing-MS-SQL
IFAIU is Oracle/FB not changed in the diagramm, or am i wrong?

Note: I'm one with red/green colors (eyes)issues. So reading/comparing the diagramms is ... hard/impossible for me, sorry. Is there a way you change the colors for the Access-layers?
Something like Blue = mMORot, Green = Zeos, Gray = x etc? That would help me very much.

I would like to use the link as reference, Arnaud.

Cheers, Michael

Re: Zoes7.2 upgrade

This blog post was run on another computer.
And I do not have access to this Oracle DB instance anymore...

The reference are the numbers in the SAD 1.18 pdf documentation, not those blog posts, which are pretty transient.
