In this tutorial, you will learn about the MySQL DROP Table statement to drop the table from the MySQL database. Here we will see how to drop single and multiple columns from the MySQL database.
MySQL Drop Table Statement Introduction
MySQL provides a MySQL DROP TABLE statement to drop single or multiple tables from a database.
The basic syntax of MySQL DROP TABLE statement.
DROP [TEMPORARY] TABLE [IF EXISTS] tbl_name [, tbl_name] ... [RESTRICT | CASCADE]
let’s break down the above syntax.
- The DROP TABLE statement removes the table along with their data permanently from the MySQL database.it also allows us to remove more than one table simultaneously.
- The TEMPORARY option allows us to remove only a temporary table.it ensures that you are deleting only temporary tables.
- IF EXISTS conditionally drop a table if a table exists. If you are trying to delete a non-existing table, MySQL raises a note which can be retrieved using the show warning statement.
- table_name represents the table name you want to delete, you can remove multiple tables. All the table names are separated by commas.
MySQL DROP TABLE Examples
DROP TABLE allows us to delete single and multiple columns. Here we will see all the examples one by one.
To delete only the table in MySQL, you have to assign one single table name with the MYSQL DROP TABLE statement.
First, we will create a table students table. This table is only for testing purposes.
Example: Create a Table in MySQL
CREATE TABLE students ( st_id INT PRIMARY KEY, name VARCHAR(100) NOT NULL, roll_no INT, UNIQUE(roll_no) );

Example:- Drop a table in MySQL
Now, we will drop the students table using the
DROP TABLE statement.
DROP TABLE students;
How to drop multiple tables in MySQL ?
To delete multiple columns, you need to assign all the table names separated by commas.
First of all, we will create three tables students1, students2, and students3 for testing purpose.
Create the first table:
CREATE TABLE students1 ( st_id INT PRIMARY KEY, name VARCHAR(100) NOT NULL, roll_no INT, UNIQUE(roll_no) );
Create the second table:
CREATE TABLE students2 ( st_id INT PRIMARY KEY, name VARCHAR(100) NOT NULL, roll_no INT, UNIQUE(roll_no) );
Create the third table:
CREATE TABLE students3 ( st_id INT PRIMARY KEY, name VARCHAR(100) NOT NULL, roll_no INT, UNIQUE(roll_no) );
You can use SHOW DATABASES to see all the created databases.
Example:- Drop multiple tables in MySQL
Now, we will drop all the tables which have been created above using the
DROP TABLE statement.
DROP TABLE students1, students2, students3;
Again, You can use SHOW DATABASES to see the database.
Delete non-existing table using MYSQL DROP TABLE statement
When you are trying to delete a non-existing table using the MYSQL DROP TABLE statement, MySQL generates a note.
Let see what happens when we are trying to delete the non-existing table.
Example: Delete a non-existing table in MySQL
DROP TABLE students4;
MySQL issue the following note:
ERROR 1051 (42S02): Unknown table 'college.students4'
