CREATE Database

The SQLite sqlite3 command is used to create new SQLite database. You do not need to have any special privilege to create a database.


Basic syntax of sqlite3 command is as follows:

$sqlite3 DatabaseName.db

Always, database name should be unique within the RDBMS.


If you want to create new database <testDB.db>, then SQLITE3 statement would be as follows:

$sqlite3 testDB.db
SQLite version 2013-01-09 11:53:05
Enter ".help" for instructions
Enter SQL statements terminated with a ";"

Above command will create a file testDB.db in the current directory. This file will be used as database by SQLite engine. If you have noticed while creating database, sqlite3 command will provide a sqlite> prompt after creating database file successfully.

Once a database is created, you can check it in the list of databases using SQLite .databases command as follows:

seq  name             file
---  ---------------  ----------------------
0    main             /home/sqlite/testDB.db

You will use SQLite .quit command to come out of the sqlite prompt as follows:


The .dump Command

You can use .dump dot command to export complete database in a text file using SQLite command at command prompt as follows:

$sqlite3 testDB.db .dump > testDB.sql

Above command will convert the entire contents of testDB.db database into SQLite statements and dump it into ASCII text file testDB.sql. You can do restoration from the generated testDB.sql in simple way as follows:

$sqlite3 testDB.db < testDB.sql

At this moment your database is empty, so you can try above two procedures once you have few tables and data in your database. For now, let's proceed to next chapter.
