It can be used for creating and editing database files. DB Browser is an example of an SQLite browser. With the SQLite browser, we can directly manipulate the files in the SQLite database. It is integrated directly into the host program. The whole database system is contained in a single library. It is a C library that has direct access to its stored files. Since no server is required for setting up SQLite, an SQLite database instance can be created just like opening a file. SQLite runs without the need for a separate server process.

Other Major Database Management Systems in this series include Microsoft’s SQL Server, MySQL, PostgreSQL, IBM’s DB2, and Oracle Database. It is basically a relative database management system used for storing structured data in large tables. You should now look at the Sqlite documentation and see what other data manipulation is possible.Sqlite is a lightweight but feature-rich database management system that is widely used in embedded systems like mobile devices. The above should be enough to get you started.
Sqlite3 mydatabase.sqlite "SELECT id from person where name='$1' "Īnd to see the power of sqlite, run the script to find the id of the person with the name Tom. Lets look inside the files and see what it looks like. $ echo -e '#!/bin/bash\nsqlite3 mydatabase.sqlite "SELECT id from person where name='"'"'$1'"'"' "\n' > personid_by_name.sh You don’t need to worry about this if you just create the scripts directly in a text editor, but for now just follow along and just enter the lines below. The second script is a little more complicated, because the sql WHERE clause for the column “name” needs to be inside single quotes and because of the shell escaping, there is a bit of work required to make the one line script creation work. To find the name of the person with the id 3, run the script with 3 as the argument. Now that we can see what it will do, make it executable. Sqlite3 mydatabase.sqlite "SELECT name from person where id=$1 " Lets look inside the file and see what it looks like. $ echo -e '#!/bin/bash\nsqlite3 mydatabase.sqlite "SELECT name from person where id=$1 "\n' > person_by_id.sh The first bash script will find the name of the person by id, by passing in the id as argument $1 to the script.įirst create the script with the following command. These could be created using a text editor but for simplicty can be created using a few one line commands. The next few lines create the actual scripts. If you got the output above, you are ready to create the bash scripts to do the same. $ sqlite3 mydatabase.sqlite "SELECT name from person where id=3 "
Run a quick test to make sure everything is working. Sqlite3 mydatabase.sqlite "INSERT INTO person VALUES (1, 'Jim', '123446223') \
$ sqlite3 mydatabase.sqlite "CREATE TABLE person ( id int, name varchar(30), phone varchar(30) ) " The following few commands will make a database file called mydatabase.sqlite and add a few rows of data. Set up some test dataįirst we will create a small test database so that the scripts we make will output something. If you haven’t already installed Sqlite, install it with apt-get.Īnd to see the power of sqlite, run the script to find the id of the person with the name Tom. Sqlite is quite powerful and once you get started you will see no end to the problems it can solve. The scripts below can give your bash scripts access to data that would otherwise have been very cumbersome. This is just a short introduction to get you started, and you should already be familiar with Linux and scripting before you start.

Here I will show you how to use the lightweight Sqlite database from the command line using bash scripts.
