What to lern in SQL as a Beginner
As a beginner learning SQL, there are several basic features that you should focus on. These include:
- Data Types: SQL supports different data types, such as text, numbers, dates, and Boolean values. Understanding data types is essential to correctly storing and manipulating data in a database.
- Tables: Tables are the foundation of a database. You need to learn how to create tables and define their columns, data types, and constraints.
- Queries: SQL queries are used to retrieve, update, insert, and delete data from tables. You’ll need to learn how to write basic queries, including SELECT, INSERT, UPDATE, and DELETE statements.
- Filtering and Sorting Data: You’ll need to learn how to filter and sort data using the WHERE and ORDER BY clauses in SQL statements.
- Joins: In a database with multiple tables, you’ll need to join tables to retrieve data that is related across tables. You’ll need to learn the different types of joins, including INNER JOIN, LEFT JOIN, and RIGHT JOIN.
- Aggregation Functions: Aggregation functions in SQL are used to perform calculations on data, such as finding the average, minimum, maximum, or sum of values. You’ll need to learn how to use functions like COUNT, SUM, AVG, MAX, and MIN.
- Subqueries: Subqueries are queries nested inside other queries. You’ll need to learn how to use subqueries to retrieve data from tables based on more complex conditions.
