It is also being widely adopted across all platforms, including Docker containers. In an environment with a large number of databases on a private or public cloud, automating the building of PostgreSQL instances can save a lot of time. PostgreSQL makes setting up and using databases easier and simpler both on-premises or in the cloud. Developers also choose PostgreSQL as their NoSQL database. PostgreSQL is an open-source and feature-rich ORDBMS database that competes with real-time, top-ranked databases such as Oracle. The community also receives significant contributions from various companies around the world. PostgreSQL is developed by a PostgreSQL global community, comprised of some great developers who have been working hard for decades to ensure that PostgreSQL is feature-rich and highly competitive with other open-source and commercial databases. PostgreSQL is the most preferred database in the world due to its exhaustive list of enterprise-grade features and capabilities. MySQL was taken over by Oracle a few years ago, resulting in two versions: enterprise and open source, the latter of which has attracted a lot of criticism from MySQL users due to Oracle controlling the MySQL development. This is why PostgreSQL has become a great choice for developers, and its popularity is growing exponentially with each passing day. As an RDBMS database, MySQL is not fully SQL compliant and does not have many of the features that PostgreSQL has. MySQL is known to be the world’s most popular database, whereas PostgreSQL is known as the world’s most advanced RDBMS database. PostgreSQL and MySQL are both immensely popular open-source databases, and a variety of real-time applications today utilize both. After this point-by-point analysis, we conclude that PostgreSQL is the superior choice based on its rich features and active community and support, and while the simplicity of MySQL makes it a speedy option for simple applications, PostgreSQL is particularly recommended for complex applications or large volumes of data. We cover differences in SQL syntax and compliance, ease of use, available features and customizability, performance, and scalability. It is intended for anyone who is interested in learning more about open-source databases, but is particularly valuable for those looking to decide which database system is the right choice for their organization or application. In this article we offer a detailed comparison of these two database systems and review their similarities and differences. While they share many things in common, the differences between them are significant and can be a source of confusion both for newcomers to database management and for experienced DBAs. I am always interested in new challenges so if you need consulting help, reach me at all posts by Rajendra GuptaPostgreSQL and MySQL are two of the most popular open-source relational databases today. I am the creator of one of the biggest free online collections of articles on a single topic, with his 50-part series on SQL Server Always On Availability Groups.īased on my contribution to the SQL Server community, I have been recognized as the prestigious Best Author of the Year continuously in 2019, 2020, and 2021 (2nd Rank) at SQLShack and the MSSQLTIPS champions award in 2020. I published more than 650 technical articles on MSSQLTips, SQLShack, Quest, CodingSight, and SeveralNines. I am the author of the book " DP-300 Administering Relational Database on Microsoft Azure". Hi! I am Rajendra Gupta, Database Specialist and Architect, helping organizations implement Microsoft SQL Server, Azure, Couchbase, AWS solutions fast and efficiently, fix related issues, and Performance Tuning with over 14 years of experience. Let’s set up a sample table to explore SQL Not Equal operator. You should use operator as it follows the ISO standard. The only difference is that ‘’ is in line with the ISO standard while ‘!=’ does not follow ISO standard. We can use both SQL Not Equal operators and != to do inequality test between two expressions. For example, 1011 comparison operation uses SQL Not Equal operator () between two expressions 10 and 11.ĭifference between SQL Not Equal Operator and != We use SQL Not Equal comparison operator () to compare two expressions. In this article, we will explore both operators and differences in these as well. We can have the following comparison operators in SQL. The total number of articles written by Rajendra > (Greater than) the total number of articles written by Raj. Suppose Raj wrote 85 articles while Rajendra wrote 100 articles. For example, we might compare the performance of two authors based on a number of articles. We use these operators to compare different values based on the conditions. We must have used comparison operators in mathematics in the early days. This article explores the SQL Not Equal comparison operator () along with its usage scenarios.
