.DBQ File Extension
What is a DBQ file?
Set of SQL queries saved by AutoCAD, a professional 3D CAD application; used to access records from a database table; typically created using the Query Editor, which can be accessed through the dbConnect Manager.
Individual queries can be saved by clicking Store in AutoCAD's Query Editor. DBQ files, which may contain multiple saved queries, can be exported from AutoCAD by selecting dbConnect → Queries → Export Query Set. You can import queries saved in a DBQ file by selecting dbConnect → Queries → Import Query Set.
Common DBQ files included with AutoCAD include project.dbq, repldocument.dbq, and global.dbq.
