miab3,

i got the little bug! Patch done R2270.
IMHO was it an all time issue. I made a SVN compare and the reported issue was never handled before. Can you confirm my patch?

I didn't touch the array types. Still fighting with the updates for minior String-convertations...

@EgonHugeist,

After R2270 it's fine.

Michal

@EgonHugeist,

Could you change in ZDbcDbLibMetadata.pas:
on
I will not have to constantly fix it.
This is an explanation:

miab3,

Patch done R2289 \testing7.1 (SVN)

Thank you Michal.

May i ask you if you have some benchmark tests to check a internal speed increase?

@EgonHugeist,

I did not notice a significant difference in the speed of the R2290.

[s]However, recently I noticed a drop in performance ORACLE particular read/update master-detail-subdetail (and i not are able to determine which patch caused it).
(A similar test at Firebird is three times faster than ORACLE).[/s]
I think it the fault of my ORACLE (I'll have to put it all over again).

miab3,

that's not what i mean. I'm currently working on the RawUpgrade and do optimize the String convertion routines. Tody i've killed my local working copy of the dbc-layer. Inbetween i'm a little bit frustrated. Well i'll try to merge "save" changes to SVN as good as possible (since i've again over 3000 changes lines and fixing the current code becames a merging hell).

But i could also send you a copy before commit the changes to verify if it works and even if it's faster. Currently i can't say when i'm ready. Mainproblems i have are CodePage inconsistend CodePages like FireBird CharacterSet "NONE". Where each column can have a different CodePage. Currently i've no idea how to tell the RowAccessor which col uses which CP. (not a problem on DBC-Layer but a huge problem on the Component layer).

So i think it could take a while (one or two weeks). And even more would it be interesing if this patch speeds up something. ??

It might be worthwhile to publish the current version 7.10 as stable before you start a revolution.
(It looks me the stable, more stable than 7.03).

I found and fixed a loads of remaining issues on 7.0/7.1. But you're right. We should relase 7.0.4-stable and go beta with 7.1. Mark and me already wrote about..

This fix(R2374) improves in the D2006/D2007 and in XE2 too.

miab3,

thanks, Michal. Yes this was a nasty bug. Equal to R2375 (;

Now we could also assume ftCurrency for fields with equal or less decimal digits of 4. What do you think?

Btw. http://zeosdownload.firmos.at/downloads/snapshots/ its just a snapshot. Mark will merge the latest fixes and 7.0.4 (a bugfix release) will be released the next days...

7.1 goes beta next days too (:
