.SH NAME
|
|
.B sqlite3
|
|
\- A command line interface for SQLite version 3
|
|
|
|
.SH SYNOPSIS
|
|
.B sqlite3
|
|
.RI [ options ]
|
|
.RI [ databasefile ]
|
|
.RI [ SQL ]
|
|
|
|
.SH SUMMARY
|
|
.PP
|
|
.B sqlite3
|
|
is a terminal-based front-end to the SQLite library that can evaluate
|
|
queries interactively and display the results in multiple formats.
|
|
.B sqlite3
|
|
can also be used within shell scripts and other applications to provide
|
|
batch processing features.
|
|
|
|
.SH DESCRIPTION
|
|
To start a
|
|
.B sqlite3
|
|
interactive session, invoke the
|
|
.B 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:
|
|
.sp
|
|
$
|
|
.B sqlite3 mydata.db
|
|
.br
|
|
SQLite version 3.8.3
|
|
.br
|
|
Enter ".help" for instructions
|
|
.br
|
|
sqlite>
|
|
.B create table memos(text, priority INTEGER);
|
|
.br
|
|
sqlite>
|
|
.B insert into memos values('deliver project description', 10);
|
|
.br
|
|
sqlite>
|
|
.B insert into memos values('lunch with Christine', 100);
|
|
.br
|
|
sqlite>
|
|
.B select * from memos;
|
|
.br
|
|
deliver project description|10
|
|
.br
|
|
lunch with Christine|100
|
|
.br
|
|
sqlite>
|
|
.sp
|
|
|
|
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:
|
|
.sp
|
|
$
|
|
.B sqlite3 -line mydata.db 'select * from memos where priority > 20;'
|
|
.br
|
|
text = lunch with Christine
|
|
.br
|
|
priority = 100
|
|
.br
|
|
.sp
|
|
|
|
.SS SQLITE META-COMMANDS
|
|
.PP
|
|
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:
|
|
.sp
|
|
