SQLite shell

posted on 2014-11-23 17:43:19

While fixing a broken Proxmox install (where a sqlite file is used for housekeeping of the configuration), I came across using sqlite. Which is basically an SQL Database contained within a single file.

Clients can be either console based (i.e. apt-get install sqlite3) or graphical (see here).

While the GUI stuff is nice, for working on the server... CLI.

Here's the usually needed stuff if you need from the official documentation: (Commands for the sqlite CLI)

Often used commands:

sqlite3                               ## open cli
sqlite3 /PATH/TO/DB                   ## open cli and load db
sqlite3 -line /PATH/TO/DB "COMMMAND"  ## run COMMAND on DATABASE, 'line'-d output

# create dumps
sqlite DB '.dump' > dumpfile.sql
# replay dump
sqlite3 DB < dumpfile.sql

COMMANDs in particular:

.quit                                 ## exit cli
.help                                 ## show help
.databases                            ## show available db's
.schema [TABLE]                       ## table create statement, think `describe` in mysql
.open PATH                            ## open database at filesystem PATH

.show                                 ## show settings
.mode                                 ## show available output modes
.mode line                            ## should be mostly needed when working with the cli, default is 'list'
.mode csv                             ## guess what, excel is your friend now
.stats on                             ## useful for debugging, 'off' to turn off again
.width col1 col2 col3 ... colN        ## set column size when using `.mode column`

pragma integrity_ceck                 ## db consistency check
reindex                               ## might help when db is inconsistent
analyze                               ## update statistics for the indexes
pragma foreign_key_check              ## validate foreign key constraints
pragma encoding                       ## show encoding of db
pragma locking_mode                   ## show locking mode (normal or exclusive)
pragma DB.locking_mode=exclusive      ## set locking mode to exclusive, needed for simultaneous db accesses
pragma query_only                     ## is db readonly?
pragma query_only=BOOL                ## set db to RW or RO
pragma compile_options                ## show options with which sqlite was compiled

.mode insert                          ## show insert statements for data, useful when creating dumps
.output /PATH/TO/FILE                 ## define dumpfile
.dump                                 ## create dump
.read /PATH/TO/FILE                   ## replay dump into current db

A lot of commands can be given by dashed commands, see the man page for these.
