It's just the default extension for a text file containing T-SQL code. A .sql file isn't a database.

.sql is the extension of a script file not a database, its not an mdf/ndf/ldf file and thus cannot be attached or detached from SQL.

The caveat to this is that if someone created the DB and specified upon creation that the file extensions should be .sql instead of mdf/ndf/ldf

Shudder.

I once created a database with both the data and log files being NTFS alternate streams of a readme.txt. Just to see if I could.

I created a database with an extension of .DOC in a demo. Silly stuff is possible. Don't do that.

Indeed, just because you can, doesn't mean you should.
