SQLite JOINS
It is used to join two tables by using the common field in both of the tables. SQLite Joins’ responsibility is to combine the records from two tables. Joins can only performed on the table if they have at least one column in common and based on that column we will be combining two tables using joins. One table must contain a column that is a reference for the other table and then only we can perform the Joins.
For Example, we have two tables Teachers and Department then assume that if we have a common column as Id in both tables then we can use that column to join the two tables and the tables look like

SQLite Joins is of different types. Some are Defined Below:
- INNER JOIN

But however the RIGHT OUTER JOIN and FULL OUTER JOIN are not supported in SQLite. So, now let us try to learn more about the other three joins in the coming sentences.
Let’s discuss the SQLite Joins one by one in a detailed and Simple way.
SQLite Joins
SQLite is a server-less database engine and it is written in C programming language. It is developed by D. Richard Hipp in the year 2000. The main motive for developing SQLite is to overcome the use of complex database engines like MySQL etc. It has become one of the most popularly used database engines used in Television, Mobile Phones, web browsers, and many more. It is written simply so that it can be embedded into other applications.
In this article we will learn about the Joins in SQLite, and how it works, and also along with that, we will be looking at different types of joins in SQLite in a detailed and understandable way with examples.
