Re: Postgresql - cwstring

Jan,

Thank You for Your support. At least we remove cwstring require from our new library.
So problem is not resolved but not exists at this moment. I hope we will have spare time for this problem return.

Best regards.

Re: Postgresql - cwstring

Hello Jan,

I use plain fpc 2.6.4. Tomorrow I try 3.0.2 and I try to make testcase. What kind of test console app will be best ?
This is utf/ansi conversion problem so console entered data depends of console settings. National data at source code ?
I can’t make gui app.

Postgresql - cwstring

Hello, My new library request to add cwstring unit to uses statement. It is unix os - freebsd. After cwstring uses add my zeos connection writes wrong national data. Reading is correct but writing is corrupted. I tried latest 7.2.4. Without cwstring add everything works fine. Any suggestion please ?...

Re: ZeosLib + PostgreSQL performance - 7.0 vs 7.1 vs 7.2

Ok
I'll try this but this is old stuff and perhaps there can be problems with Metadata turned off.

But my performance tests was with metadata turned on in both cases.
Do You mean that Metadata feature is slower in newer ZEOS versions ?

Re: ZeosLib + PostgreSQL performance - 7.0 vs 7.1 vs 7.2

Hi,

Tested in sample app:
Turning UseMetadata to False reduce loading time but version difference is still present:

ZEOS 7.0.6 - Load data - was 47,674 s - is 40,453 s
ZEOS 7.1.4 - Load data - was 59,327 s - is 53,265 s

ZeosLib + PostgreSQL performance - 7.0 vs 7.1 vs 7.2

Hi, Several days ago we switch to 7.1 Zeos Lib at Delphi XE7 (before it was 7.0.3 at Delphi 2010). After upgrade our customers asked us about poor application performace. After some test we found Zeos Lib speed malfunction. We made simple tests (XE7) at 7.0.6, 7.1 and last SVN 7.2. It was very simpl...

Re: Postgresql tableoid column problem

Jan !!
Thank You very much !

It looks like everything is ok. This patch is probably not for 7.1 but i did changes manually and my code passed few tests.
I'l be testing next few days - if something will be wrong i'll make a call :)

Thanks Jan again.

It seems that solution is like above: DBConnection.Properties.Clear; DBConnection.Properties.Add('codepage=UTF8'); DBConnection.Properties.Add('client_encoding=UTF8'); Even if you have DB encoded for example in WIN1250 (as me). I think that with above properties there is online reencoding from WIN12...

Hi mdaems,

It was my mistake. That was FPC 2.2.0 version not 2.2.2. After upgrade to 2.2.2 compile was succesful.

Another my question is:

In windows You need a library: libpq74.dll. Is in FreeBSD system instaled another postgres client so aditionaly library isn't needed ??
