Using SQL Inner Join

I have an SQLite database stored on my MacBook Pro laptop that I use to track work requests. The database file is named CRQ.db, since it tracks work done under a Change Request (CRQ). Within that database are several tables two of which are "Equipment" and "Device". For every CRQ that I need to deal with, I store information on equipment that is affected by the CRQ. The equipment table has the following structure:

NameType
CRQText
DeviceText
ProjectText
NotesText

The device field holds a unique name assigned to the particular device. A device may be affected by more than one CRQ, so it can, potentially, occur multiple times in the table. A CRQ can affect multiple pieces of equipment.

The device table has the following structure:

NameType
DescriptionText Unique
ManufacturerText
ModelText
SiteText
BuildingText
RoomText
NotesText
