![]() ![]() If you choose Drop Now, it’ll delete the database immediately.įourth, once you are sure that the SQL statement is going to drop the right database, you can click the Execute button to execute the statement. If you choose Review SQL, you’ll see the SQL statement that will be executed. Third, MySQL Workbench displays a dialog to confirm the deletion. Second, right-click the database that you want to remove, for example, testdb2 and choose the Drop Schema. option. DROP DATABASE using MySQL Workbenchįirst, launch the MySQL workbench and log in to the MySQL Server. MySQL returned zero affected rows indicating that the testdb database has no tables. Output: Query OK, 0 rows affected (0.03 sec) Code language: Shell Session ( shell ) Third, drop the testdb database by issuing the DROP DATABASE statement: DROP DATABASE testdb Code language: SQL (Structured Query Language) ( sql ) Second, display all the databases using the SHOW DATABASES statement: SHOW DATABASES Code language: SQL (Structured Query Language) ( sql )ħ rows in set (0.00 sec) Code language: Shell Session ( shell ) Enter password: ******** Code language: Shell Session ( shell ) Type the password for the root user and press Enter. MySQL DROP DATABASE using mysql program exampleįirst, log in to the MySQL Server using the root user: mysql -u root -p Code language: Shell Session ( shell ) ![]() ![]() If you do not have these databases available, you can follow the previous tutorial to create them. In the next section, we will use the testdb and testdb2 created in the CREATE DATABASE tutorial. Therefore, you can use them interchangeably: DROP SCHEMA database_name Code language: SQL (Structured Query Language) ( sql ) In MySQL, the schema is the synonym for the database. The DROP DATABASE statement returns the number of tables it deleted. In this case, MySQL will terminate the statement without issuing any error. To prevent an error from occurring if you delete a non-existing database, you can use the IF EXISTS option. If you drop a database that does not exist, MySQL will issue an error. In this statement, you specify the name of the database which you want to delete after the DROP DATABASE keywords. The following shows the syntax of the DROP DATABASE statement: DROP DATABASE database_name Code language: SQL (Structured Query Language) ( sql ) Therefore, you need to be very careful when using this statement. The DROP DATABASE statement drops all tables in the database and deletes the database permanently. Introduction to the MySQL DROP DATABASE statement It is possible to specify connection parameters without entering them on the command line every time a client program is invoked.Summary: in this tutorial, you will learn how to use the MySQL DROP DATABASE statement to delete an existing database in the server. It can be done using any one of the way − mysql -port=13306 -host=127.0.0.1 To cause the port number to be used, force a TCP/IP connection. Lets see how it can be done − mysql -host= -port=13306 To specify a port number explicitly, the -port or -P option can be used. The command would connect to the server running on using the default port number (3306). (period) can also be mentioned as the host name.Ĭonnections to remote servers will use TCP/IP. This can be done by specifying the -pipe or -protocol=PIPE option. On Windows, MySQL client can be forced to use a named-pipe connection. Let us see with the example − Example mysql -host=127.0.0.1 The transport protocol can be explicitly mentioned using the -protocol=TCP option. Instead of this, the IP address or name of the local server can also be mentioned. To ensure that the client makes a TCP/IP connection to the local server, ‘-host’ or ‘-h’ needs to be specified, with a host name value of 127.0.0.1 (instead of localhost). If the host is not specified or it is a localhost, a connection to the local host occurs Mysql -h localhost -u myname -ppassword mydbĬlient programs determine the type of connection that needs to be made − Let us see this with the command − mysql -host=localhost -user=myname -password=password mydb To select a default database, add a database-name argument. To specify the host name, user name and password specifically, provide appropriate options on the command line. Since there is no such argument, mysql selects no default database. No password is sent because neither -password nor -p has been mentioned.įor mysql, the first non-option argument is considered the name of the default database. The default user name is ODBC on Windows. Since there are no parameter options, the default values will be applied − The below command invokes mysql without specifying any explicit connection parameters − mysql This is done for clients like mysql or mysqldump. Let us understand how MySQL can be connected to the database using the command-line. ![]()
