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 multiple for-
       mats.  sqlite3 can also be used within shell scripts and other applica-
       tions 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 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 3.8.3
       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
       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  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-
       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 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
       .bail ON|OFF           Stop after hitting an error.  Default OFF

INIT FILE

       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.
