¿Qué hacer si quieres aprender SQL como principiante?

One thing should be clear beforehand that SQL is not a programming language and it does not work like Java or C, it is a query language which is used to retrieve and manipulate tabular data from a relational database. Before beginning to learn SQL, you should have basic understanding of databases in general and relational databases specifically. After having the basic knowledge of relational databases, you should start learning about SQL's syntax. It is better to focus on one variant of SQL as there are various proprietary and open source options. Initially, you should start with DQL and DML and after fully understanding these, you should advance to DDL and DCL.

As a beginner in learning SQL, the first step is to set up the necessary tools. Choose a database management system (DBMS) like MySQL, PostgreSQL, SQL Server, Oracle, etc. and install the proper version on your computer. Many DBMS providers offer free versions for learning purposes, making it accessible to beginners. Additionally, install a text editor or integrated development environment (IDE) for writing and executing SQL queries efficiently.

Once the tools are in place, dive into learning the SQL syntax. Familiarize yourself with basic concepts such as SELECT statements, filtering data with WHERE clauses, sorting with ORDER BY, and joining tables. Online tutorials, books, and interactive courses are excellent resources for grasping fundamental SQL concepts. Start with simple queries and gradually progress to more complex ones as you gain confidence in your skills.

SQL is easy to learn and all query are straightforward. For my opinion someone went learn Sql it should start with Select, update,delete create and insert queries and be familiar with them then pass to joint with their diffrent types.

To truly excel in SQL as a beginner, I emphasize the importance of dedicating countless hours to practice. Regular, consistent practice is the cornerstone of mastering SQL. I've personally invested significant time in honing my skills, devoting countless hours to writing and executing SQL queries, manipulating databases, and tackling real-world scenarios. This commitment to practice not only strengthens your understanding of SQL concepts but also builds confidence in your ability to navigate complex database environments effectively.
