If thedatabase file does not exist, it will be created.  If the database filedoes exist, it will be opened.For example, to create a new database file named "mydata.db", createa table named "memos" and insert a couple of records into that table:.sp$ .B sqlite3 mydata.db.brSQLite version 3.1.3.brEnter ".help" for instructions.brsqlite>.B create table memos(text, priority INTEGER);.brsqlite>.B insert into memos values('deliver project description', 10);.brsqlite>.B insert into memos values('lunch with Christine', 100);.brsqlite>.B select * from memos;.brdeliver project description|10.brlunch with Christine|100.brsqlite>.spIf no database name is supplied, the ATTACH sql command can be usedto attach to existing or create new database files.  ATTACH can alsobe used to attach to multiple databases within the same interactivesession.  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 asa single argument.  Multiple statements should be separated bysemi-colons.For example:.sp$ .B sqlite3 -line mydata.db 'select * from memos where priority > 20;'.br    text = lunch with Christine.brpriority = 100.br.sp.SS SQLITE META-COMMANDS.PPThe interactive interpreter offers a set of meta-commands that can beused to control the output format, examine the currently attacheddatabase files, or perform administrative operations upon theattached databases (such as rebuilding indices).   Meta-commands arealways prefixed with a dot (.).A list of available meta-commands can be viewed at any time by issuingthe '.help' command.  For example:.spsqlite>.B .help.nf.cc |.databases             List names and files of attached databases.dump ?TABLE? ...

Designed to be easily parsed byscripts or other programs.TP.B \-listQuery results will be displayed with the separator (|, by default)character between each field value.  The default..TP.BI \-separator\  separatorSet output field separator.  Default is '|'..TP.BI \-nullvalue\  stringSet string used to represent NULL values.  Default is ''(empty string)..TP.B \-versionShow SQLite version..TP.B \-helpShow help on options and exit..SH INIT FILE.B sqlite3reads an initialization file to set the configuration of theinteractive environment.  Throughout initialization, any previouslyspecified setting can be overridden.  The sequence of initialization isas follows:o The default configuration is established as follows:.sp.nf.cc |mode            = LISTseparator       = "|"main prompt     = "sqlite> "continue prompt = "   ...> "|cc ..sp.fio If the file .B ~/.sqlitercexists, it is processed first.can be found in the user's home directory, it isread 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..SH SEE ALSOhttp://www.sqlite.org/.brThe sqlite-doc package.SH AUTHORThis manual page was originally written by Andreas Rottmann<rotty@debian.org>, for the Debian GNU/Linux system (but may be usedby others).
