Updating Blof Field


I have the following column in an entity:

[Column('WCBullets', [TColumnProp.Lazy])]
FWCBullets: TBlob;

I need to update it based on other columns. It contains RTF which I generate.

How can I do this in theTAureliusModelEvents.OnUpdating event?

I cannot change the structure of the underlying database because it is shared with a VCL app.



You can simply change its content and then set the RecalculateState event parameter to true so that it's taken into account when saving to the database.

Thanks but I was rather hoping for an example of how to change the content of the blob :grinning:

There are severa examples in documentation:


Thanks. Wagner.
