SQLITE3(1)                                                          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 multiple formats.  sqlite3 can also be used within shell scripts and other applications to  pro-
       vide 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 3.1.3
       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 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:

       $ 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, exam-
       ine 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:

       sqlite> .help
       .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

                                column   Left-aligned columns.  (See .width)

OPTIONS
       sqlite3 has the following options:

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

       -echo  Print commands before execution.

       -[no]header
              Turn headers on or off.

       -column
              Query  results  will  be  displayed  in  a  table like form, using whitespace characters to separate the
              columns and align the output.

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

       -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.

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

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

       -version
              Show SQLite version.

       -help  Show help on options and exit.



INIT FILE
       sqlite3 reads an initialization file to set the configuration of the interactive environment.  Throughout  ini-
       tialization, 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 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.
