SQL Basics šŸ“

Introduction

SQL stands for Structured Query Language. It's a programming language designed for managing data held in a relational database management system (RDBMS).

SQL Syntax and Keywords

SQL statements are written in plain text and consist of keywords, identifiers, and literals. Keywords are predefined words with special meanings, like SELECT, FROM, WHERE, etc. Identifiers are user-defined names for tables, columns, and other database objects. Literals are fixed values, such as numbers, strings, and dates.

Creating a Database and Table

To create a database, use the CREATE DATABASE statement followed by the database name.

sql
CREATE DATABASE your_database_name;

To create a table, use the CREATE TABLE statement followed by the table name and column definitions.

sql
CREATE TABLE your_table_name ( column1 datatype, column2 datatype, ... );

šŸ“ Note: Replace your_database_name and your_table_name with your desired database and table names. Choose appropriate data types for columns.
