Upgrade from v7.2.14

[DelphiTom]

Hello everyone,

Does anyone know if there are additional steps to upgrade from Zeos v7.2.14 to Zeos 8?
I'm using Delphi Sydney.

Thanks

Hello Tom,

I am not sure if you have read the Release Notes? In a lot of cases Zeos 8.0 will work as a drop in replacement for Zeos 7.2.14.

The biggest pitfalls I remember:

• driver versioning: In Zeos 7.2.14 you could use driver names like firebird-3. This has changed, now please just use firebird (or other driver names without version numbers)
• Zeos 8.0 now supports BCD field types. So when Zeos 7.2 generated a TFloatField for a numeric(x,y) field in the database you now will get a TBCDField or TFMTBcdField. This will lead to problems when you have persistent fields or do type casts.
• If you were still using the ntwdblib.dll, Zeos will now refuse to use it. Use FreeTDS instead.
• Zeos now has its own Parameter type: TZParam. Again this might lead to probelms in code when typecasting or having variables parameter objects.

But it really makes sense to read the release notes.

Best regards,

Jan
