I'm new to ZeosLib. Some weeks ago I decided using PostgreSQL 'cause we had very bad support experience using Oracle XE versions. Zeos was the only freeware supporting our old project written in Delphi 7(...don't ask...) First of all, to preserve backward compatibility I have replaced NOCI with Zeos and I have configured it to use Oracle. It works well, nothing else had to be modified in my project. As next step, I have implemented SQLite support as many users aren't using client-server architectures - also having no problems at all... Just a few SQL script related cosmetics... Now I want to implement the PostgreSQL support but I get a lot of trouble.
Using Zeos v7.0.4 stable I was unable to edit my data fields. We are using the good old TQuery - TDataSource - TDBEdit (and TDB* components) structure. TZQuery.Edit and TZQuery.Append (Insert) aren't setting field's ReadOnly=False... or whatever. Fact is that I can not edit them. If I create a for cycle to set TZQuery.Fields.ReadOnly=False, then everything is OK. But this is not required for Oracle and SQLite, so I think #1. I make something wrong, or #2. there is a bug in Zeos.
I have then downloaded version 7.1 beta. Now it enables all fields (this predicts assumption #2), but when I try ZQuery.ApplyUpdates then it runs on error "Could not determine data type of parameter $2". I googled for this and I have found this: http://zeoslib.sourceforge.net/viewtopi ... =38&t=3817 (this confirms assumption #2.)
I have added ZEOS_TESTING_ONLY to Zeos.inc. Now it works, but I think that this is not the best solution to release my software for my customers. So what should I do? As I see, this is a known issue, but I am not an expert, I just want to use the known components and to focus to the main part of my job and not worrying about database issues...
Thanks for attention!
Kind Regards,
Ákos
