[wix-users] Unable to Uninstall Patch

[Ven H]

Thank you very much, Rob. In my case, I have the MsiPatchMetadata table in
the Patch.msp, when opened using Orca and the other conditions are also
fine.

So, it looks like I am not getting how Patch works with SqlScript elements.
It will be great, if someone can please explain how to create Patch for
SqlScript for DB. I couldn't find much info on that.

Regards,
Venkatesh
