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 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 3.1.3
       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,  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:

       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
       .explain ON|OFF	      Turn output mode suitable for EXPLAIN on or off.
       .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 ?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
       .quit		      Exit this program
       .read FILENAME	      Execute SQL in FILENAME
       .schema ?TABLE?	      Show the CREATE statements
       .separator STRING      Change separator used by output mode and .import
       .show		      Show the current values for various settings
       .tables ?PATTERN?      List names of tables matching a LIKE pattern
       .timeout MS	      Try opening locked tables for MS milliseconds
       .width NUM NUM ...     Set column widths for "column" mode
       sqlite>

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.

       -bail  Stop after hitting an error.

       -interactive
	      Force interactive I/O.

       -batch Force batch I/O.

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

       -cmd command
	      Run command before reading stdin.

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

       -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).

       -stats Print memory stats before each finalize.

       -version
	      Show SQLite version.

       -vfs name
	      Use name as the default VFS.

       -help  Show help on options and exit.

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
       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.
