How to create different types of columns in a MySQL table on Kali Linux?

- Open the MySQL shell by typing mysql -u root -p in the terminal and entering your password when prompted.
- Create a new database (if required) by executing the following command: CREATE DATABASE database_name;
- After creating the database, switch to that database using the command: USE database_name;
- Create a new table by executing the following command, specifying the desired column names and their types: CREATE TABLE table_name ( column_name1 data_type1, column_name2 data_type2, ... ); Here, column_name refers to the name of the column, and data_type determines the type of data the column will hold. Some commonly used data types include: INT: Integer values VARCHAR(n): Variable-length string of maximum length n DATE: Date values in the 'YYYY-MM-DD' format FLOAT: Floating-point numbers For example, to create a table named "students" with two columns (name and age), the SQL command would be: CREATE TABLE students ( name VARCHAR(50), age INT );
- Once the table is created, you can insert data into the table using the INSERT INTO statement: INSERT INTO table_name (column_name1, column_name2, ...) VALUES (value1, value2, ...); For example: INSERT INTO students (name, age) VALUES ('John Doe', 20);
Now you have successfully created a table with different types of columns in MySQL on Kali Linux.
