Probably not but it would be better to assume yes.
No such database exists. Many states don't even record gun sales. Best bet is just to adhere to laws of the state you are in using the resources suggested here.
There was a PA woman (IIRC employed in PA as a prison guard) who was initially jailed in NJ after a traffic stop as a result of a data base search revealing she had a CCW. The cop asked if she gad her firearm with her and she answered truthfully, yes. Gov. Christie had to step in to get her released. There have been several other cases reported on firearm related websites of the NJ cops asking out of state CCW holders if they had their firearm with them. So CCW permit data bases are readily accessible to cops.
