VirtualDac Several Erros.

Post by wesleybobato » Mon 05 Dec 2016 16:26

Hi Support

I'm wondering why I should buy VirtualDac.

I Developed a Test Application with VirtualDac.
Comparing with TClientDataset, TFDMemTable and TkbmMemTable.

Unfortunately VirtualDac Was No Better Than None.
TVirtualTable Not Working with TBytesField

Byte Array, Cause Errors.
It was much slower in several tests.

TVirtualQuery Does Not Support TBytesField with Select.

Select sum (bytesfield) from table?

Select count (bytesfield [1]) from table?

I'm Sharing a Video and a Small Project.

Do You Want to Fix Those Mistakes?

Thanks for your attention.
