According to the project’s website, “SQLite is a C-language library that implements a small, fast, self-contained, high-reliability, full-featured, SQL database engine.” Also, it is open-source.

The great feature of SQLite is that it is easily implemented in mobile applications. That is to say since it is not managed as a service, it makes it possible for our applications to move along with the database.

On the other hand, SQLite boasts that it is the most used database manager in the world, and if we take into account the great number of mobile applications, we can believe it.

The command will vary by version, to make sure which one it is, you can visit the SQLite website.

We already have the SQLite source code downloaded. Create a folder for SQLite and access it.

mkdir sqlite3 && cd sqlite3

And then, unzip the file in this folder:

tar xvfz ../sqlite-autoconf-3330000.tar.gz

Access the generated folder:

cd sqlite-autoconf-3330000/

And configure the code to start the compilation:

./configure

Compile SQLite with the make command:

make 

And finally, install it:

sudo make install

In the end, you can check the results by running the command sqlite3. For example, to show the installed version:

sqlite3 --version
3.33.0 2020-08-14 13:23:32 fca8dc8b578f215a969cd899336378966156154710873e68b3d9ac5881b0ff3f

So, that way you can install the latest version of SQLite on Ubuntu 20.04 Enjoy it.

Conclusion

Many developers need the latest version of certain programs. One of them can be the package manager and take advantage of all the new features it can bring.

Now you know how to install the latest version of SQLite on Ubuntu 20.04

So, share this post and join our Telegram channel and our Facebook Page. Also, you can buy us a coffee.

The post How to install the latest version of SQLite on Ubuntu 20.04? appeared first on Linux Windows and android Tutorials.

SQLite is a small, reliable and very fast database engine. It is one of the most efficient database engines in the world. In part, thanks to that made in C Language which makes it very efficient in managing the resources of the system.

In like manner, the development of SQLite is so important that many major companies participate in it. This is done through the SQLite Consortium. In addition, all the code is available to be downloaded, viewed and reused for being open source.

So, let us start.

Install SQLite on Ubuntu 20.04 / 18.04

SQLite is a very light and powerful program. It will not take long. In addition, to simplify the whole process, SQLite is available in the official repositories of Ubuntu 18.04 and Linux Mint 19.

So, first, you need to update the APT cache.

:~$ sudo apt update

Then, you can search the repositories for SQLite-related packages.

:~$ sudo apt-cache search sqlite

Then you can start installing SQLite. To do this, run the following command:

:~$ sudo apt install sqlite3

After that, you can check the installed version by running the following command.

:~$ sqlite3 --version

And that’s it.

The first steps with SQLite

Now, it is convenient that I show you the first steps with SQLite. Let us create a test database.

:~$ sqlite3 example.db

In the SQL language, databases are composed of Tables. So, let us create an example table named “Student”.

sqlite> CREATE TABLE Student
               (
               Id VARCHAR(25) NOT NULL,
               Name VARCHAR(25) NOT NULL,
               Last_Name VARCHAR(25) NOT NULL,
               Age INTEGER(2) NOT NULL,
               CONSTRAINT pk_Student PRIMARY KEY (Id)
               );

In the previous image, it is shown that we have created a table with several fields and where the Id field is the primary key. This is SQL language so you have to learn it in order to use SQLite correctly.

After that, you can check that the table was created.

sqlite> .tables

Then, you can insert some values on the newly created table.

sqlite> INSERT INTO Student (Id, Name, Last_Name, Age) VALUES ('Xy01','Jon','Snow',18);

Finally, use the Select command to show the data inserted.

sqlite> SELECT * FROM Student;

Now, you can use SQLite to make projects. Type .exit to close SQLite shell.

Bonus: How to install SQLite Browser

As a bonus, I will teach you how to install the SQLite Browser which is a front-end for SQLite. It is quite complete and will help with data visualization and data management. So, run these commands:

:~$ sudo add-apt-repository -y ppa:linuxgndu/sqlitebrowser
:~$ sudo apt update
:~$ sudo apt install sqlitebrowser

Next, open it from the main menu.

For example, you can open the database previously created. Click on the OpenDatabase button and search for it.

After that, you can browse the data.

Enjoy it.

Conclusion

SQLite is a great database application and if we learn to use it, it would be a great help for our projects. Installing it is very easy and gives us a lot of work possibilities. In addition, the SQLite Browser makes the workflow too easy.

TablePlus is a modern intuitive application that is for managing relational and non-relational databases. Its main advantage is that it is compatible with many database management systems including popular, MySQL, MariaDB, PostgreSQL or SQLite. But it also supports NoSQL databases such as Apache Cassandra and MongoDB. In addition, the team of developers promises that more will come.

I like the minimalist and modern design of the application that gives a sensation of being an application according to these times. However, the application is not free and you have to pay to use it.

On the other hand, the application has stable and consolidated versions for Windows and macOS but recently they have published an Alpha version for Linux. And the best thing is that these alphas are free and we will be able to try them.

So, let’s take a look.

Install TablePlus on Ubuntu

To install it in Ubuntu 18.04, you have to add the application repository. First, you have to add the GPG key to it.

:~$ wget -O - -q http://deb.tableplus.com/apt.tableplus.com.gpg.key | sudo apt-key add - 

Then, add the repository by creating a file called tableplus.list in /etc/apt/sources.list.d/ and add the following:

:~$ sudo nano /etc/apt/sources.list.d/tableplus.list

deb [arch=amd64] https://deb.tableplus.com/debian tableplus main

Save the changes and close the editor. I use the terminal a lot but you can create the file with another editor like gedit.

After that, refresh the APT cache and finally install Tableplus.

:~$ sudo apt update 
:~$ sudo apt install tableplus

Then, you can run it from the main menu.

A little look to this tool for Database management

As soon as you open it you will be able to configure a new connection to a database server. There you will have to configure the connection. You will also have the option to test the connection before starting it.

In my case, I have used an instance of MariaDB to test. By default, when you establish the connection, you see the following way:

On the left side, the list of tables and below you can switch between databases. If you select a table, the data will be shown like this:

As we can see, everything is very clean, tidy, modern. One of the characteristics of this client is that everything looks very integrated with the GTK system. I haven’t tried it with QT.

Thanks to the lower buttons, you will be able to verify the structure of the table very quickly.

Also, you can limit the number of results you get.

So this is a very small look at this application.

Remember it’s an alpha and the developers say there will be weekly updates so don’t forget to update your equipment.

Also, keep in mind that the application will gradually evolve but it is a good start. It has been fast, efficient and easy to use all this with a pretty nice interface.

For more information, I recommend you visit the application website.

So, that is it. Do not forget to share.

SQLite small but powerful

Unlike MySQL, MariaDB or PostgreSQL, SQLite does not function as a system service that can be managed from systemctl. Rather it is a rather small and lightweight self-contained database manager.

On the other hand, being so small does not make it less powerful, but on the contrary supports databases up to 2 Terabytes in size. It is an acceptable size and enough for many cases.

The application is open-source and cross-platform with binaries for Linux, Windows and macOS. In addition, it is self-contained i.e. it does not require external libraries to work. This and the fact that it is done in C language make it a very efficient database management system.

Finally, there is no need to worry about the data, because they are perfectly compatible with the popular MySQL or PostgreSQL.

Install SQLite on CentOS 8

In this new version of CentOS, we have a very recent version of SQLite in the official repositories. This makes the installation really simple.

First, open a terminal and update the system:

:~$ su
:~# dnf update

This way you will have all the security patches installed correctly in your system. With this your system will be more secure and stable.

Then, proceed to install SQLite using the following command:

:~# dnf install sqlite

At the end of the download to install will be ready for work. It’s that simple.

Working with SQLite on CentOS 8

To enter the SQLite command console, simply type the SQLite command. There you create a temporary database to start the work.

:~$ sqlite3

A second step I recommend is to show the SQLite help to know which commands we can apply. At least at the beginning, it is good to do it.

> .help

If you want to create a new permanent database, you must exit the shell and execute the sqlite3 command followed by the name of the database to be created.

To exit the shell, use .exit.

:~$ sqlite3 example.db

And on it create a new table with a simple structure like the one I will do. Of course in daily work, these tables will be long and complex.

> create table example(
...> id int(3),
...> name varchar(30),
...> last_name varchar(30)
...> );

Then, you can insert some data:

> INSERT INTO example(id,name,last_name) VALUES(1,'Angelo','Osradar);

Then, Check the results:

> SELECT * FROM example;

Now, you can start to work with SQLite on CentOS 8.

Conclusion

With SQLite we will have the certainty of using a good database manager but without spending too many resources. This way we will be able to have a database of considerable sizes with an amazing speed. In this post, you have learned to use it and take the first steps with it.

As I mentioned at the beginning, managing data in a database that uses SQL in a terminal is not appropriate. In addition, insecure is impractical. So recently I showed you some graphical clients for Git, today I will do the same with SQL. This way you will be able to work more and better.

Let us start.

Graphical clients for SQL

1) MyWebSQL

I start with MyWebSQL. It is a web application to manage SQL databases. However, it places special emphasis on MySQL.

MyWebSQL is built with PHP so it requires a web server to function. Its graphical interface is great because it resembles a desktop application. It is well done and very well taken care of.

You can find much more information about MyWebSQL in our post about it or on their website.

2) DBeaver

DBeaver is a very powerful graphical SQL client. It is an open source desktop application that stands out for its simplicity and power. It supports many SQL database managers such as DBeaver, SQLite or PostgreSQL. That’s why many developers trust their work with SQL to DBeaver.

On the other hand, it requires Java to work so maybe those who have modest hardware will not like the idea.

We have also talked about DBeaver on our site so we invite you to stop by this post to learn how to install it.

3) PHPMyAdmin

If we have to talk about a very popular SQL tool in the educational field, that is PHPMyAdmin. It is a very popular and simple web interface for SQL language that contains everything you need to manage databases and SQL statements.

Being a web interface, it requires a web server, with all the advantages and disadvantages of the case. Ideal when you have a shared development of some application or centralized data.

Of course, PHPMyAdmin is available for Linux in a very simple way and is open source. So, you can install it on CentOS.

4) PGAdmin

If there is an SQL client specialized in PostgreSQL that is pgAdmin. This powerful PostgreSQL client is a work of art. Its interface is the best in all of Linux because it is simple and very flexible.

PgAdmin is open source and is available for all Linux through a web server and Python.

Conclusion

Here are some of the most popular graphical SQL clients on Linux. Their use makes it much easier to manage the data in our SQL database. So it only remains for you to try and tell us your experience.

The post Graphical clients for SQL in Linux appeared first on Linux Windows and android Tutorials.

MyWebSQL is an open source tool to manage data stored in MySQL or MariaDB. However, it is not only limited to them but is compatible with PostgreSQL and SQLite. Therefore, we are in the presence of an essential tool on the client side.

So, let us install MyWebSQL on Ubuntu 18.04.

1. Install Apache web server and PHP

First, it is necessary to install a web server. Therefore, I will install the Apache Web server. It is simple, free and it is available in the official Ubuntu repositories, so everything will be faster.

:~$ sudo apt install apache2

Once the installation has finished, the service will start automatically. However, if you want Apache to run at system startup, run the following command:

:~$ sudo systemctl enable apache2

After that, you need to install PHP, some of their modules and other necessary packages.

:~$ sudo apt install php libapache2-mod-php php php-common php-mbstring php-gd php-intl php-curl php-xml php-mysql php-pgsql php-mysql php-bcmath unzip wget

Verify the installed PHP version with the following command.

:~$ php -v

Then, it is a good idea to test the Apache and PHP installation. To do it, create a new file called test.php on the /var/www/html/ folder.

:~$ sudo nano /var/www/html/test.php

Now, add the following:

<?php
phpinfo();
?>

Press CTRL + O to save the changes and CTRL + X to close the editor.

After that, restart the Apache web server service.

:~$ sudo systemctl restart apache2

Finally, open your web browser and go to http://SERVER_IP/test.php.

If the PHP information is shown in the browser as in the previous image. Then everything is fine.

2.- Install a Database manager

As I said before, MyWebSQL is compatible with several database handlers. In this section, you can install the one you want. However, for this example, I will use MySQL which is perfectly compatible with MyWebSQL so let’s go for it.

:~$ sudo apt install mysql-server

Now, it is time to set a new root password for MySQL. You can do it using the mysql_secure_installation script.

:~$ sudo mysql_secure_installation

Now, answer the question like the following way:

Change root password? Y
Remove anonymous users? Y
Disallow root login remotely? Y
Remove test database and access to it?  Y
Reload privilege tables now?  Y

So, that is all for MySQL.

Next, create a new user for MyWebSQL. You can use the user and password you want.

:~$ sudo mysql -u root -p
USE mysql;
GRANT ALL PRIVILEGES ON *.* TO 'angelo'@'localhost' IDENTIFIED BY 'Angelo12.,';
FLUSH PRIVILEGES;
exit;

3. Install MyWebSQL on Ubuntu 18.04

now it’s time has come to install MyWebSQL, first, you need to download it. For now, the last stable version of the program is 3.7. So, run this command:

:~$ wget https://newcontinuum.dl.sourceforge.net/project/mywebsql/stable/mywebsql-3.7.zip

Next, decompress it on the Apache root folder.

:~$ sudo unzip mywebsql-3.7.zip -d /var/www/html

After that, set the correct permissions.

:~$ sudo chown -R www-data:www-data /var/www/html/mywebsql/
:~$ sudo chmod -R 775 /var/www/html/mywebsql/

Now, complete the installation from the web interface. Open the web browser and go to http://SERVER_IP/mywebsql/install.php

After that, access to the MariaDB instance using the right credentials.

Then, you will see the main screen of the application.

So, that is it.

Conclusion

MyWebSQL is a great help tool for data management using MySQL, MariaDB, PostgreSQL or SQLite. It’s a great alternative to PHPMyAdmin and honestly, I like it better.
