How can we take a backup of the single database by using mysqldump client program?

MySQLMySQLi Database

By using mysqldump client program we can take the backup of a database into a file having the extension ‘.sql’. it can be understood with the help of following example −

Example

In this example, with the help of mysqldump client program, we are taking the backup of a database named ‘tutorials’ in a file named ‘tutorials.sql’. The following command will do this −

C:\mysql\bin>mysqldump -u root tutorials > tutorials.sql

The above command will create a file named ‘turorials.sql’ in the bin folder of MySQL. This file will contain drop table, create a table and insert command for all the tables in the tutorials database. Following is a partial output of tutorials.sql showing the dump information of ‘rtgs’ table −

--
-- Table structure for table `rtgs`
--
DROP TABLE IF EXISTS `rtgs`;
/*!40101 SET @saved_cs_client = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `rtgs` (
   `id` int(11) DEFAULT NULL,
   `name` varchar(20) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
/*!40101 SET character_set_client = @saved_cs_client */;
--
-- Dumping data for table `rtgs`
--

LOCK TABLES `rtgs` WRITE;
/*!40000 ALTER TABLE `rtgs` DISABLE KEYS */;
INSERT INTO `rtgs` VALUES (1,'Ram'),(2,'Shyam');
/*!40000 ALTER TABLE `rtgs` ENABLE KEYS */;
UNLOCK TABLES;
/*!40103 SET TIME_ZONE=@OLD_TIME_ZONE */;

/*!40101 SET SQL_MODE=@OLD_SQL_MODE */;
/*!40014 SET FOREIGN_KEY_CHECKS=@OLD_FOREIGN_KEY_CHECKS */;
/*!40014 SET UNIQUE_CHECKS=@OLD_UNIQUE_CHECKS */;
/*!40101 SET CHARACTER_SET_CLIENT=@OLD_CHARACTER_SET_CLIENT */;
/*!40101 SET CHARACTER_SET_RESULTS=@OLD_CHARACTER_SET_RESULTS */;
/*!40101 SET COLLATION_CONNECTION=@OLD_COLLATION_CONNECTION */;
/*!40111 SET SQL_NOTES=@OLD_SQL_NOTES */;
