sqlite3 - Unix, Linux Command
sqlite3 - A command line interface for SQLite version 3
sqlite3 [options] [databasefile] [SQL]
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.
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:
SQLite version 3.1.3
Enter ".help" for instructions
create table memos(text, priority INTEGER);
insert into memos values(deliver project description, 10);
insert into memos values(lunch with Christine, 100);
select * from memos;
deliver project description|10
lunch with Christine|100
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
sqlite3 -line mydata.db select * from memos where priority > 20;
text = lunch with Christine
priority = 100
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:
csv Comma-separated values
column Left-aligned columns. (See .width)
html HTML <table> code
insert SQL insert statements for TABLE
line One value per line
list Values delimited by .separator string
tabs Tab-separated values
tcl TCL list elements
sqlite3 has the following options:
-init file ||
Read and execute commands from
file , which can contain a mix of SQL statements and meta-commands.
Print commands before execution.
Turn headers on or off.
Query results will be displayed in a table like form, using
whitespace characters to separate the columns and align the
Query results will be output as simple HTML tables.
Query results will be displayed with one value per line, rows
separated by a blank line. Designed to be easily parsed by
scripts or other programs
Query results will be displayed with the separator (|, by default)
character between each field value. The default.
-separator separator |
Set output field separator. Default is |.
-nullvalue string |
Set string used to represent NULL values. Default is
Show SQLite version.
Show help on options and exit.
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
o The default configuration is established as follows:
mode = LIST
separator = "|"
main prompt = "sqlite> "
continue prompt = " ...> "
o If the file
~/.sqliterc exists, it is processed first.
can be found in the users home directory, it is
read and processed. 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.
