SQLITE3(1)               General Commands Manual               SQLITE3(1)

NAME
       sqlite3 - A command line interface for SQLite version 3

SYNOPSIS
       sqlite3 [options] [databasefile] [SQL]

SUMMARY
       sqlite3  is  a terminal-based front-end to the SQLite library that
       can evaluate queries interactively and display the results in mul‐
       tiple  formats.  sqlite3 can also be used within shell scripts and
       other applications to provide batch processing features.

DESCRIPTION
       To start a sqlite3 interactive session, invoke the sqlite3 command
       and  optionally provide the name of a database file.  If the data‐
       base 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", cre‐
       ate 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
       sqlite>

       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  sup‐
       plied  as  a single argument.  Multiple statements should be sepa‐
       rated by semi-colons.

       For example:

       $ sqlite3 -line mydata.db 'select * from memos  where  priority  >
       20;'
           text = lunch with Christine
       priority = 100

   SQLITE META-COMMANDS
       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-com‐
       mands 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:

       sqlite> .help
       .backup ?DB? FILE      Backup DB (default "main") to FILE
       .bail on|off           Stop after hitting an error.  Default OFF

              output.

       -cmd command
              run command before reading stdin

              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

       -vfs name
              Use name as the default VFS.

INIT FILE
       sqlite3  reads  an initialization file to set the configuration of
       the interactive environment.  Throughout initialization, any  pre‐
       viously specified setting can be overridden.  The sequence of ini‐
       tialization 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 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.
