sqlite3 - A command line interface for SQLite version 3
sqlite3 [options] [databasefile] [SQL]
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.
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 .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 .trace FILE|off Output each SQL statement as it is run .vfsname ?AUX? Print the name of the VFS stack .width NUM1 NUM2 ... Set column widths for "column" mode .timer ON|OFF Turn the CPU timer measurement on or off sqlite>
sqlite3 has the following options: -bail Stop after hitting an error. -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 out- put. -cmd command run command before reading stdin -csv Set output mode to CSV (comma separated values). -echo Print commands before execution. -init file Read and execute commands from file , which can contain a mix of SQL statements and meta-commands. -[no]header Turn headers on or off. -help Show help on options and exit. -html Query results will be output as simple HTML tables. -interactive Force interactive I/O. -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. -mmap N Set default mmap size to N -nullvalue string Set string used to represent NULL values. Default is '' (empty string). -separator separator Set output field separator. Default is '|'. -stats Print memory stats before each finalize. -version Show SQLite version. -vfs name Use name as the default VFS.
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.
