sqlite3: I won’t begin to try and explain

I have sqlite3 on my list of applications, and I know you can access sqlite database files with it, in console mode.


But I’ll be dead honest: I haven’t a clue what to do next. The .help command ticks off a huge list of commands, and I am hopelessly lost as to what any one of them — except perhaps for .exit — does. 😯

So I mention this only out of a sense of obligation, but I’m just crossing it off my list with this post.

And because I know if I don’t mention it, somewhere down the line, I’ll get that e-mail that starts off with, “Hey, what about sqlite3? Why didn’t you didn’t mention that one?! I use that every day in my job as. …” πŸ™„

So there it is, for that unnamed person in the future. Enjoy. πŸ˜€

    you can create and examine sqlite3-based databases. If you use firefox you have several sqlite databases on your filesystem. try “find ~/.mozilla -iname “#.sqlite”.

    Example open the formhistory.sqlite of my firefox: “sqlite3 .mozilla/firefox/y1zixjcr.default/formhistory.sqlite”
    and show the tables with “.tables”
    moz_deleted_formhistory moz_formhistory

    Now you can examine the tables with the “.show” command

    sqlite> .schema moz_formhistory
    CREATE TABLE moz_formhistory (id INTEGER PRIMARY KEY, fieldname TEXT NOT NULL, value TEXT NOT NULL, timesUsed INTEGER, firstUsed INTEGER, lastUsed INTEGER, guid TEXT);
    CREATE INDEX moz_formhistory_index ON moz_formhistory(fieldname);
    CREATE INDEX moz_formhistory_lastused_index ON moz_formhistory(lastUsed);
    CREATE INDEX moz_formhistory_guid_index ON moz_formhistory(guid);

    With this you can sql-select statements to view the content… (you need the “;” at end of the line)

    select * from moz_formhistory;
    3580|q|com manager|1|1399461996446000|1399461996446000|WHIEPMjvTdeXXXX

    If you have an sqlite file produced by some other program, you can start sqlite:

    sqlite3 programsdatabase.sqlite3

    View the tables in that file:


    Show data from the table:

    SELECT * FROM tablename;

    It’s useful if you want to tweak some settings, if you use a program which uses SQLite database at the backend.

    I used a lot of the word “use” πŸ™‚
