The above command won't show any visible output on the screen. $ mysqldump -u root -p -all-databases > database_dump.sql Exampleįollowing is the query to export all the databases in a host using the -all-databases option − In such scenario, we can use the "-all-databases" option of mysqldump command. Instead, it exports the data of both the tables into the specified file.įor instance, you have multiple databases in your host and you want to export all of them in a single query. Once we executed the above query, it wont display any ouptut. $ mysqldump -u root -p TUTORIALS employees students > output_file.sql Now, let us export two tables named EMPLOYEES and STUDENTS into the 'datadump2.sql' as follows − Let us fetch the list of tables in the TUTORIALS database using the below query −Īs we can in the output below, we have three tables present in TUTORIALS database − Tables_in_tutorials Here, we are creating the EMPLOYEES table − > output_file.sqlīefore exporting, let us create two new tables ( STUDENTS and EMPLOYEES) in the above-created TUTORIALS database using the following query − Mysqldump -u username -p database_name table1 table2. We can also export only specific tables in a database using the mysqldump command-line tool. Exporting only Specific Tables in Database Instead, the 'data-dump.sql' file will be saved in the current working directory of the command prompt or terminal where you executed the command. The above command will not produce any visual output. $ mysqldump -u root -p TUTORIALS > data-dump.sql Once we execute the below statement, we need to enter our MySQL server password. Here, we are using the mysqldump command-line statement to export the TUTORIALS database to the 'datadump.sql' file. INSERT INTO CUSTOMERS (ID,NAME,AGE,ADDRESS,SALARY) VALUES The following query inserts 7 records into the CUSTOMERS table − Let us also create a table named CUSTOMERS in the above-created database − >: This symbol exports the output of the mysqldump command into a file named output_file_path.įirst of all, create a database named TUTORIALS using the following query −Įxecute the below query to select the current database as TUTORIALS − This is where the backup data will be stored. Output_file_path: It is the path of the backup file. Username: It is the MySQL username to use when connecting to the database.ĭatabase_name: It is the name of the database to be exported. $ mysqldump -u username -p database_name > output_file_path It can be used to back up an entire database, specific tables, or even specific rows based of a table.įollowing is the syntax of mysqldump command to export a database − The mysqldump command-line tool is used in MySQL to create backups of databases. The simplest way of exporting a database is by using the mysqldump command-line tool. You can export entire database or just a portion of it. Hence we perform database export.Įxporting a database in MySQL is commonly used for backup purposes or transferring data between servers. Since their data is highly confidential, it becomes necessary to back up the database and restore it whenever necessary. It structures data in the form of tables and views so that data handling becomes easier making organizations prefer using MySQL to manage their company's confidential data.
