Opening database file from within SQLite command-line shell

Question

I'm using the SQLite Command Line Shell. As documented, I can open a database by supplying it as an argument to the executable:

sqlite3 data.db

I cannot figure out how to open a database file from within the tool after having invoked it without supplying the file as a command-line argument (if I, say, double-click sqlite3.exe in Windows). What is the command within the SQLite shell tool to specify a database file?

Answer 1

You can attach one and even more databases and work with it in the same way like using sqlite dbname.db

sqlite3
:
sqlite> attach "mydb.sqlite" as db1;

and u can see all attached databases with .databases

where in normal way the main is used for the command-line db

.databases
seq  name             file                                                      
---  ---------------  ----------------------------------------------------------
0    main                                                                       
1    temp
