Hi, I apologize for not located and for not knowing the SET BIND statement or DataTypeCompatibility configuration. However, I've read the Firebird 4.0 Beta2 Release Notes focusing specifically on my problem. I suggest to include mentions to the SET BIND and DataTypeCompatibility at these segments of the documentation: - https://snipboard.io/k7rBA1.jpg - https://snipboard.io/sVgdXp.jpg That's only a suggestion.
Thanks a lot! The DataTypeCompatibility configuration is very convenient. I'll start a new thread to report a supposed related bug. -- Eliezer Riani Em dom., 30 de ago. de 2020 às 19:09, Eliezer Riani <eliezerri...@gmail.com> escreveu: > Hi, > > I have some systems developed in Delphi, PHP, and Java. > I used Firebird 2.5.9 until I've updated to the Firebird 3.0.6 without any > change in my SQL's. > > I am now testing Firebird 4.0 from your daily builds and have a problem. > The feature implemented in the issue > http://tracker.firebirdsql.org/browse/CORE-694 introduced a change in the > CURRENT_TIME and CURRENT_TIMESTAMP functions that returns a new SQL data > type. > This new data type is necessary to use the new improvement, but the > enforced change of the return type in these two functions causes a rupture > in existing compiled and legacy systems that became impossible to update > them to FB 4.0. > > I've listed some samples, like old Jaybird drivers, the current Delphi > Community Edition data access components (FireDAC), the current > implementation of IBObjects, and the PHP driver that I've looked at the > GitHub repository but don't found the new data types implementation. > > I'm changing the calls to CURRENT_TIMESTAMP to CAST(CURRENT_TIMESTAMP AS > TIMESTAMP) in the case of my systems and all is running fine for now. > > My question, in this case, is not about my problem but about the > compatibility questions that can cause slow adoption of the new version on > behalf of a new feature that will not be used by all users. > I propose to add a configuration or a way to check that the client > implementation does not support the new data type and then return a legacy > TIMESTAMP data. > At this link are possible to see some tests screenshots: > https://drive.google.com/drive/folders/1U1Y0zcUwZjiY3HNBnABwN6XtMAyR8WYz > > -- > Eliezer Riani >
