It enables -you to type in queries interactively, issue them to SQLite and see the -results. Alternatively, you can specify SQL code on the command-line. In -addition it provides a number of meta-commands. +.B sqlite3 +is a terminal-based front-end to the SQLite library that can evaluate +queries interactively and display the results in multiple formats. +.B sqlite3 +can also be used within shell scripts and other applications to provide +batch processing features. .SH DESCRIPTION -This manual page documents briefly the -.B sqlite -command. -This manual page was written for the Debian GNU/Linux distribution -because the original program does not have a manual page. -.SS GETTING STARTED -.PP -To start the sqlite program, just type "sqlite" followed by the name -the file that holds the SQLite database. If the file does not exist, a -new one is created automatically. The sqlite program will then prompt -you to enter SQL. Type in SQL statements (terminated by a semicolon), -press "Enter" and the SQL will be executed. - -For example, to create a new SQLite database named "ex1" with a single -table named "tbl1", you might do this: +To start a +.B sqlite3 +interactive session, invoke the +.B 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: .sp -.nf -$ sqlite3 ex1 -SQLite version 3.0.8 +$ +.B sqlite3 mydata.db +.br +SQLite version 3.1.3 +.br Enter ".help" for instructions -sqlite> create table tbl1(one varchar(10), two smallint); -sqlite> insert into tbl1 values('hello!',10); -sqlite> insert into tbl1 values('goodbye', 20); -sqlite> select * from tbl1; -hello!|10 -goodbye|20 +.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 -.fi + +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 sqlite3 -line mydata.db 'select * from memos where priority > 20;' +.br + text = lunch with Christine +.br +priority = 100 +.br +.sp .SS SQLITE META-COMMANDS .PP -Most of the time, sqlite just reads lines of input and passes them on -to the SQLite library for execution. But if an input line begins with -a dot ("."), then that line is intercepted and interpreted by the -sqlite program itself. These "dot commands" are typically used to -change the output format of queries, or to execute certain prepackaged -query statements. - -For a listing of the available dot commands, you can enter ".help" at -any time. For example: +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.
