The content for these slides will come from the database_field_references.odt chapter of the P2J Conversion Reference.

The slides filename in Bazaar (in the p2j_training/developer1/ project) should be database_field_references.odp.

Please note that I have not yet had a chance to review this chapter, other than a cursory skim, so if you see something that looks questionable, please ask about it. This also means we might need to tweak the slides later, if I find we need to make changes to the chapter, once I have a chance to review.

Question:
...
Progress 4GL also provides the ASSIGN statement, which allows multiple fields to be assigned in batch, postponing the field and index validation until after the last assignment was executed. In the converted code, the generated DMO property assignment will follow the same rules as when the ASSIGN statement was not used (i.e. the property setter will be invoked to set its value).
...

Does it mean the converted code will support and implement assigning in a batch with postponing field and index validation?

Answer:
Yes, it must. Not doing so would break application code which depends upon this deferred validation.

Question:

Can we say the P2J works the same as 4GL here or P2J simulates this behavior by different approaches?

Answer:
It is enough to say it works the same way. It is not necessary to discuss the internal details of the runtime implementation.
