-sqlite is a terminal-based front-end to the SQLite library. It enables
-you to type in queries interactively, issue them to SQLite and see the
-results. Alternatively, you can specify SQL code on the command-line. In
-addition it provides a number of meta-commands.
+.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
-This manual page documents briefly the
-.B sqlite
-command.
-This manual page was written for the Debian GNU/Linux distribution
-because the original program does not have a manual page.
-.SS GETTING STARTED
-.PP
-To start the sqlite program, just type "sqlite" followed by the name
-the file that holds the SQLite database. If the file does not exist, a
-new one is created automatically. The sqlite program will then prompt
-you to enter SQL. Type in SQL statements (terminated by a semicolon),
-press "Enter" and the SQL will be executed.
-
-For example, to create a new SQLite database named "ex1" with a single
-table named "tbl1", you might do this:
+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
-.nf
-$ sqlite3 ex1
-SQLite version 3.0.8
+$
+.B sqlite3 mydata.db
+.br
+SQLite version 3.1.3
+.br
Enter ".help" for instructions
-sqlite> create table tbl1(one varchar(10), two smallint);
-sqlite> insert into tbl1 values('hello!',10);
-sqlite> insert into tbl1 values('goodbye', 20);
-sqlite> select * from tbl1;
-hello!|10
-goodbye|20
+.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
-.fi
+
+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

.SS SQLITE META-COMMANDS
.PP
-Most of the time, sqlite just reads lines of input and passes them on
-to the SQLite library for execution. But if an input line begins with
-a dot ("."), then that line is intercepted and interpreted by the
-sqlite program itself. These "dot commands" are typically used to
-change the output format of queries, or to execute certain prepackaged
-query statements.
-
-For a listing of the available dot commands, you can enter ".help" at
-any time. For example:
+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
+sqlite>
+.B .help
.nf
.cc |
-sqlite> .help
-.dump ?TABLE? ... Dump the database in an text format
+.databases List names and files of attached databases
+.dump ?TABLE? ... Dump the database in an SQL text format
.echo ON|OFF Turn command echo on or off
.exit Exit this program
.explain ON|OFF Turn output mode suitable for EXPLAIN on or off.
- "off" will revert to the output mode that was
- previously in effect
.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 Set mode to one of "line(s)", "column(s)",
- "insert", "list", or "html"
-.mode insert TABLE Generate SQL insert statements for TABLE
-.nullvalue STRING Print STRING instead of nothing for NULL data
+.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
- "sqlite > " and " ...> "
- with the strings MAIN and CONTINUE
- CONTINUE is optional.
.quit Exit this program
.read FILENAME Execute SQL in FILENAME
-.reindex ?TABLE? Rebuild indices
.schema ?TABLE? Show the CREATE statements
-.separator STRING Change separator string for "list" mode

- .echo

.SH INIT FILE

-command line arguments to set up sqlite exactly the way you want it.
