NAME

sqlite3 - A command line interface for SQLite version 3

SYNOPSIS

sqlite3 [options] [databasefile] [SQL]

SUMMARY

sqlite3 is a terminal-based front-end to the SQLite library that can
evaluate queries interactively and display the results in multiple
formats. sqlite3 can also be used within shell scripts and other
applications to provide batch processing features.

DESCRIPTION

To start a sqlite3 interactive session, invoke the sqlite3 command
and optionally provide the name of a database file. If the database
file does not exist, it will be created. If the database file does
exist, it will be opened.

For example, to create a new database file named "mydata.db", create
a table named "memos" and insert a couple of records into that table:

$ sqlite3 mydata.db
SQLite version 3.43.0 2023-08-11 17:45:23
Enter ".help" for usage hints.
sqlite> create table memos(text, priority INTEGER);
sqlite> insert into memos values('deliver project description', 10);
sqlite> insert into memos values('lunch with Christine', 100);
sqlite> select * from memos;
deliver project description|10
lunch with Christine|100
sqlite>

If no database name is supplied, the ATTACH sql command can be used
to attach to existing or create new database files. ATTACH can also
be used to attach to multiple databases within the same interactive
session. This is useful for migrating data between databases,
possibly changing the schema along the way.

Optionally, a SQL statement or set of SQL statements can be supplied
as a single argument. Multiple statements should be separated by
semi-colons.

For example:

$ sqlite3 -line mydata.db 'select * from memos where priority > 20;'
text = lunch with Christine
priority = 100

SQLITE META-COMMANDS
The interactive interpreter offers a set of meta-commands that can be
used to control the output format, examine the currently attached
database files, or perform administrative operations upon the
attached databases (such as rebuilding indices). Meta-commands are
always prefixed with a dot (.).

A list of available meta-commands can be viewed at any time by
issuing the '.help' command. For example:

sqlite> .help

The available commands differ by version and build options, so they
are not listed here. Please refer to your local copy for all
available options.

INIT FILE

sqlite3 reads an initialization file to set the configuration of the
interactive environment. Throughout initialization, any previously
specified setting can be overridden. The sequence of initialization
is as follows:

o The default configuration is established as follows:

mode = LIST
separator = "|"
main prompt = "sqlite> "
continue prompt = " ...> "

o If the file ${XDG_CONFIG_HOME}/sqlite3/sqliterc or ~/.sqliterc
exists, the first of those to be found is processed during startup.
It should generally only contain meta-commands.

o If the -init option is present, the specified file is processed.

o All other command line options are processed.
