Hello,

is there a way to influence the binding process between SnapObjects and a database (specifically Oracle) yet?

The issue we're facing is that when reading from an Column that has the type NUMBER, SnapObjects requires the property in the C# Model to be a decimal, which doesn't make a lot of sense if the property/column in question is for example an ID.

This feature has already been asked for in late 2019 (https://community.appeon.com/index.php/qna/q-a/different-binding-for-oracle-and-sql-server-number-columns), so I was wondering if this is possible yet.

If not, is there any other way to resolve this? I've tried to create a struct that allows for casting between decimal and int, but SnapObjects doesn't seem to care about whether or not the assignment would be possible, it's just looking for the decimal type and won't accept anything else. Creating an entirely different model just for Oracle would be very unwieldy and hard to maintain.

Kind regards,

Peter

Hi Peter,

There is still no way to influence the binding process between SnapObjects and a database. So you still need to maintain different models for each database.

If you want this feature, we suggest that you submit an enhancement ticket on our support portal (at https://www.appeon.com/standardsupport). This way, our product team will analyze this request when they plan to extend SnapObjects in the future. 

Regards,

Logan

Hi Peter,

For Datatype conversion unlike PowerBuilder which allows conversions between numeric data types, C# has quite strict controls over this.

For data types that are not allowed to convert to another data type implicitly in C#, the migrator may do forced conversions based on its deduction of the data type.

Please refer to the following guide for rules on datatype conversions.

or you can always open a support ticket for more support. 

 

Regards!
