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 for-
mats. sqlite3 can also be used within shell scripts and other applica-
tions 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:
$ sqlite3 mydata.db
SQLite version 3.1.3
Enter ".help" for instructions
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
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 ses-
sion. 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-
$ 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
.exit Exit this program
.explain ON|OFF Turn output mode suitable for EXPLAIN on or off.
.header(s) ON|OFF Turn display of headers on or off
.help Show this message
.import FILE TABLE Import data from FILE into TABLE
.indices TABLE Show names of all indices on TABLE
.mode MODE ?TABLE? Set output mode where MODE is one of:
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
.nullvalue STRING Print STRING in place of NULL values
.output FILENAME Send output to FILENAME
.output stdout Send output to the screen
.prompt MAIN CONTINUE Replace the standard prompts
.quit Exit this program
.read FILENAME Execute SQL in FILENAME
.schema ?TABLE? Show the CREATE statements
.separator STRING Change separator used by output mode and .import
.show Show the current values for various settings
.tables ?PATTERN? List names of tables matching a LIKE pattern
.timeout MS Try opening locked tables for MS milliseconds
.width NUM NUM ... Set column widths for "column" mode
sqlite3 has the following options:
Read and execute commands from file , which can contain a mix of
SQL statements and meta-commands.
-echo 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 out-
-html Query results will be output as simple HTML tables.
-line 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
-help 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 user's home directory, it is read and processed. It should gen-
erally only contain meta-commands.
o If the -init option is present, the specified file is processed.
o All other command line options are processed.
