In this tutorial you will learn how to delete database and table using SQL.
You can use the
DROP TABLE statement to easily delete the database tables that you no longer need. The
DROP TABLE statement permanently erase all data from the table, as well as the metadata that defines the table in the data dictionary.
DROP TABLE removes one or more tables. The syntax can be given with:
Here, table1_name, table2_name, ... are the names of the tables that you want to delete.
Let's try to remove a database table using the
DROP TABLE statement.
If you remember back to create table chapter, we've created a table persons in our demo database. The following statement will remove this table permanently from the database.
DROP TABLE persons;
After executing the above command, if you try to perform any operation on the persons table, like selecting the records from it, you'll get an error message.
Similarly, you can delete a database using the
DROP DATABASE statement. The following command will permanently remove the demo database from the database server.
DROP DATABASE demo;
Now if you try to select the demo database using the
USE demo; statement, you'll get an error message saying "Unknown database" or "Database does not exist".
