Re: Best/Right approch for master/Detail

LGPL, our code is not open Just a quick question... I'm far away from completely understanding all conditions of licenses (or being a lawyer) but according to LGPL changes made to the original source must be made public, no? we are not modifying the library in any way and not deriving from library ...

Re: TZAbstractDataSet too slow to iterate 7668 rows

if your dataset is TZquery you can iterate over DbcResultSet, s/t like

Code: Select all

    
    with (DataSet as TZQuery).DbcResultSet do
    begin
      BeforeFirst;
      while Next do
      begin
	 GetIntByName('')
      end;
    end;

Re: Best/Right approch for master/Detail

No - what I am saying is that using transactions is better than using the cached updates feature of Zeos. what about starting with his topology and how his users are gonna use his application. Just to make that clear: Connection losses of applications have not been a concern for any of the applicat...

Re: Best/Right approch for master/Detail

@marsupilami you are kidding, right? you just telling him to use long-living transactions instead of short ones, maybe on localhost, but on a local network or over the internet it's the worst he can do. believe me, I spend last years rewriting every long transaction to a short one to prevent daily c...

Re: ZeosLib can't correctly compare Extended value when creating update query

it's definitely regression, you can't compare two floats this way, https://floating-point-gui.de/errors/comparison/ just load some decimal number to the dataset, update dataset without changes (Edit and Post) and zeos will create update query that contains your decimal field even field not changed. ...

Re: ReadOnly Field

i resolved it by manually setting ReadOnly to False

Code: Select all

        Field.ReadOnly := False;
        Field.Value := Value;
        DataSet.Post;

Re: FB random Invalid BLOB ID

i'ts not fixed by r4715 (i'm testing just 7.2-patches branch), i'll try to create small demo for you EDIT: seems i can't create simple demo, it looks like its some kind of error in Firebird... Edit2: im trying to bisect it FB 3.0.4 will return error, FB 3.0.3 returns some wrong data see attachments ...
