Hi All,
I switched to PostgreSQL some time back and in truth don't ever go near it. I have a need to find a particular device history for a period of about 6 hrs back in August. Just to add some background to the request, the local police decided to inform me today that they arrested a drunk driver on my property back then and NOW want me to give them written permission for being on my property. Strange, very strange. I still haven't invested in cameras, which will be rectified very soon. However I have a beam sensor on my driveway entrance, I now want to query that device for a set period. I have next to no knowledge of SQL but would love some help.
TIA - Colly
