.B sqlcipher

is a terminal-based front-end to the SQLCipher library that can evaluate

queries interactively and display the results in multiple formats.

.B sqlcipher

can also be used within shell scripts and other applications to provide

batch processing features.

To start a

.B sqlcipher

interactive session, invoke the

.B sqlcipher

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:

.sp

$

.B sqlcipher mydata.db

.br

SQLite version 3.8.3

.br

Enter ".help" for instructions

.br

sqlite>

.B create table memos(text, priority INTEGER);

.br

sqlite>

.B insert into memos values('deliver project description', 10);

.br

sqlite>

.B insert into memos values('lunch with Christine', 100);

.br

sqlite>

.B select * from memos;

.br

deliver project description|10

.br

lunch with Christine|100

.br

sqlite>

.sp

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:

.sp

$

.B sqlcipher -line mydata.db 'select * from memos where priority > 20;'

.br

text = lunch with Christine

.br

priority = 100

.br

.sp

.PP

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:

.sp

sqlite>

.B .help

.nf

.cc |

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

.bail ON|OFF Stop after hitting an error. Default OFF

.databases List names and files of attached databases

.dump ?TABLE? ... Dump the database in an SQL text format

If TABLE specified, only dump tables matching

LIKE pattern TABLE.

.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.

With no args, it turns EXPLAIN on.

.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

If TABLE specified, only show indices for tables

matching LIKE pattern TABLE.

.load FILE ?ENTRY? Load an extension library

.log FILE|off Turn logging on or off. FILE can be stderr/stdout

.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 Use STRING in place of NULL values

.open ?FILENAME? Close existing database and reopen FILENAME

.output FILENAME Send output to FILENAME

.output stdout Send output to the screen

.print STRING... Print literal STRING

.prompt MAIN CONTINUE Replace the standard prompts

.quit Exit this program

.read FILENAME Execute SQL in FILENAME

.restore ?DB? FILE Restore content of DB (default "main") from FILE

.schema ?TABLE? Show the CREATE statements

If TABLE specified, only show tables matching

LIKE pattern TABLE.

.separator STRING Change separator used by output mode and .import

.show Show the current values for various settings

.stats ON|OFF Turn stats on or off

.tables ?TABLE? List names of tables

If TABLE specified, only list tables matching

LIKE pattern TABLE.

.timeout MS Try opening locked tables for MS milliseconds

.TP

Query results will be displayed in a table like form, using

whitespace characters to separate the columns and align the

output.

.TP

run

.I command

before reading stdin

.TP

Set output mode to CSV (comma separated values).

.TP

Print commands before execution.

.TP

.TP

Show help on options and exit.

.TP

Query results will be output as simple HTML tables.

.TP

Force interactive I/O.

.TP

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

.TP

Query results will be displayed with the separator (|, by default)

character between each field value. The default.

.TP

Set default mmap size to

.I N

.TP

Set string used to represent NULL values. Default is ''

(empty string).

.TP

Set output field separator. Default is '|'.

.TP

Print memory stats before each finalize.

.TP

Show SQLite version.

.TP

Use

.I name

as the default VFS.

.B sqlcipher

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:

.sp

.nf

.cc |

mode = LIST

separator = "|"

main prompt = "sqlite> "

continue prompt = " ...> "

|cc .

.sp

.fi

o If the file

.B ~/.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.
