SQLITE3(1)                  General Commands Manual                 SQLITE3(1)

       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 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 3.8.8
       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-

       For example:

       $ 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 data‐
       base files, or perform  administrative  operations  upon  the  attached
       databases (such as rebuilding indices).   Meta-commands are always pre‐
       fixed with a dot (.).

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

       sqlite> .help
       .backup ?DB? FILE      Backup DB (default "main") to FILE

       sqlite3 has the following options:

       -bail  Stop after hitting an error.

       -batch Force batch I/O.

              Query  results  will  be  displayed  in a table like form, using
              whitespace characters to separate the columns and align the out‐

       -cmd command
              run command before reading stdin

       -csv   Set output mode to CSV (comma separated values).

       -echo  Print commands before execution.

       -init file
              Read and execute commands from file , which can contain a mix of
              SQL statements and meta-commands.

              Turn headers on or off.

       -help  Show help on options and exit.

       -html  Query results will be output as simple HTML tables.

              Force interactive I/O.

       -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

       -list  Query results will  be  displayed  with  the  separator  (|,  by
              default) character between each field value.  The default.

       -mmap N
              Set default mmap size to N

       -nullvalue string
              Set  string used to represent NULL values.  Default is '' (empty

       -separator separator
              Set output field separator.  Default is '|'.

       -stats Print memory stats before each finalize.

              Show SQLite version.

       -vfs name
              Use name as the default VFS.

       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 ~/.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.
