Thanks i'will try

Hi all, i'm using TZSequence for my autoincrement fields whithout problem. Anyway i'd like to set a value for the generator, looking at the code i saw that it's not possible. I know that i can use a query to update the value but i prefer to use the component. Can you add this features? thanks, DarkB...

Solved with a workaround: i've replaced with: bye,

Ok they work. It's all ok if a put a DBMemo, but if i want to do it manually it's doesn't save my strings: TZTable1.Edit; Stream := TZTable1.CreateBlobStream(TZTable.FieldByName('memo'), bmWrite); try Memo1.Lines.SaveToStream(Stream); TZTable1.Post; finally Stream.Free; end; The LoadFromStream inste...

Does Blob field works on firebird? I have a TZTable with a blob field and a memo into a form. I'm trying to save and load memo's lines into/from a Blob field, but nothing happens no exception raised. It shold be the load from stream problem?

tnx,
DarkBrain

The easyest way is to create a generator into the firebird DB (CREATE GENERATOR gen_pippo) and than use the component TZSequence plus the TZTable.

To locate your line of code, download and install something like MadExcept which will trap the exception and also show you a call stack to locate the path to the exception. Thanks for your tips, it's very usefull!!! Any here is what i found: Following is the reply I got from someone at Borland abou...

I can't find it. Ah if it can help, the exception is reised in a loop and it doesn't end. Where i should look to trace the zeoslib code?

tnx,

Hi DarkBrain, it should work as you described, but a little bit more information would be useful: What DB? What Version of DB? Firebird 1.5 for windows I suppose you are using ZeosLib 6.5.1? Yep, are there some patch? Where? What is your failing line of code? This is strange because my delphi7 does...

Hi all,
are LookupKeyFields and KeyFields capable of multiple fields to obtain a primary key to search into LookupDataSet? I'm using semicolon to separete them but a EDataBaseError is raised (Field not found)

thanks,
DarkBrain

Yes it's strange also for me, and the lack of documentation doesn't help. Anyway this article helped me: http://seegernet.koolhost.de/zeosforum/kb.php?mode=article&k=6 when i start a manual transaction it's turned off automatically. In practice Autocommit can't be false, so why is here? bye, Dar...

Very intresting feature, but how many DBMS can handle these generators? Oracle and db2 seems ok but the others?
