SQLite is self-contained, which means no external dependencies. SQLite is very small and light weight, less than 400KiB fully configured or less than 250KiB with optional features omitted. SQLite comes with zero-configuration, which means no setup or administration needed.Ī complete SQLite database is stored in a single cross-platform disk file. SQLite does not require a separate server process or system to operate (serverless). SQLite accesses its storage files directly. SQLite engine is not a standalone process like other databases, you can link it statically or dynamically as per your requirement with your application. It is a database, which is zero-configured, which means like other databases you do not need to configure it in your system. SQLite is an in-process library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine. The source code for SQLite is in the public domain. SQLite is one of the fastest-growing database engines around, but that's growth in terms of popularity, not anything to do with its size. SQLite is a software library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine. All this data is hypothetical and you can create in any of your existing databases.This chapter helps you understand what is SQLite, how it differs from SQL, why it is needed and the way in which it handles the applications Database. You can execute the code below to create and populate data into these two tables. I am going to create two tables first – table ‘PizzaCompany’ that manages different branches of Pizza outlets in a few cities and table ‘Foods’ that stores food distribution details across these companies. Let’s try to understand the concept of Inner Join through an interesting data sample that deals with a Pizza Company and its food distribution. You can omit it while writing your queries and can use only ‘Join’ as well. Note – We will use the keyword ‘Inner’ Join in this article for the sake of more clarity. In short, Inner Join is the default keyword for Join and both can be used interchangeably. SQL Inner Join clause is the same as Join clause and works the same way if we don’t specify the type (INNER) while using the Join clause. When the Join condition is met, it returns matched rows in both tables with the selected columns in the SELECT clause. Inner Join syntax basically compares rows of Table1 with Table2 to check if anything matches based on the condition provided in the ON clause. The intersection part in black below shows the data retrieved using Inner Join in SQL Server. The result of this join will be a new result set that returns matching rows in both these tables. This join is based on a logical relationship (or a common field) between the tables and is used to retrieve data that appears in both tables.Īssume, we have two tables, Table A and Table B, that we would like to join using SQL Inner Join. Inner Join clause in SQL Server creates a new table (not physical) by combining rows that have matching values in two or more tables. This article targets all about the Inner Join in SQL Server, so let’s head over to it. To get a quick overview of all these joins, I would recommend going through this link, SQL Join types overview and tutorial. There are four basic types of Joins in SQL Server – Inner, Outer (left, right, full), Self and Cross join. In a real-world relational database, data is structured in a large number of tables and which is why, there is a constant need to join these multiple tables based on logical relationships between them. Join is the widely-used clause in the SQL Server essentially to combine and retrieve data from two or more tables. In this article, we will demonstrate how we can employ SQL Inner Join to query and access data from multiple tables that store this incessantly growing data in the SQL databases.īefore we get started with SQL Inner Join, I would like to call out SQL Join here. Organizations are generating and analyzing unmatched volumes of data with each passing minute.
