Does any of the VirtualDAC products offer cloned cursors? (like in clientdatasets).

To load data from another dataset, there is the Assign method in VirtualDAC. For example, you can find the description of this method for VirtualTable component by the link : https://www.devart.com/virtualdac/docs/ ... bject).htm

That wont do, then i have duplicated the data (doubled the amount of used ram) and how do i sync it? I need the same data but available through multiple cursors.

Currently, VirtualDAC has no cloned cursor functionality. You can leave your suggestion at our UserVoice ( https://devart.uservoice.com/forums/104 ... ed-cursors ) and if many users vote for your suggestion, we will implement it.

Does Uniquery have it? I see that Firedac's query have cloned cursor and also load from file.

Now VirtualDAC and UniDAC don't support CloneCursor functionality like TClientDataSet. We plan to add this functionality in one of the next VirtualDAC and UniDAC versions. You can vote for this feature at UserVoice to speed up the implementation.
