Introduction:

Have you lost your crucial MySQL database objects like table, index, column, view, etc. due to DB corruption? Struggling hard to bring them back? If your answer is ‘Yes’, then you must check out this post.

While handling MySQL databases, it is pretty common to encounter database object deletion. However, it typically happens due to database corruption.

Well, in this write-up, I will discuss how to recover MySQL database objects after fixing the DB corruption by using advanced MySQL database recovery software. Here, I’ll also mention the manual method to retrieve database objects with less effort.

Methods to Recover MySQL Database Objects

Follow the below step-by-step methods to get back the lost DB objects like table, index, column, view, etc.

Method 1- Backup & Restore Database Using mysqldump

The mysqldump is an efficient utility that can dump the DB including the SQL statements necessary to rebuild a database. Although the dump file by default includes SQL commands in order to restore the tables & data.

Steps to Backup from the Command Line via mysqldump

In order to back up the MySQL database, you have to try the below syntax:

sudo mysqldump -u [user] -p [database_name] > [filename].sql

• Here, you have to replace the [user] with your username & password (if required).
• [database_name] is a path & filename of a DB.
• The “>” command states the output.
• The [filename] is a path & filename that you need to save your dump file.

Other instances:

If you want to back up the entire DBMS (Database Management System):

mysqldump --all-databases --single-transaction --quick --lock-tables=false > full-backup-$(date +%F).sql -u root -p

If you want to back up more than one database, then use:

sudo mysqldump -u [user] -p [database_1] [database_2] [database_etc] > [filename].sql

Steps to Restore the MySQL via mysqldump

Step 1- First, Create the New Database

First of all, on the system hosting the DB, use MySQL to create the new database.

Ensure to give it a name the same as the DB you lost. However, this will create the file through mysqldump which will simply import the data.

Step 2- Restore the MySQL Dump

In order to perform MySQL recovery from backup, you have to enter the below syntax:

mysql -u [user] -p [database_name] < [filename].sql

Ensure to include the [database_name] & [filename] in a path.

It is likely that [database_name] is in a root directory on the host machine, thus you may not need to add a path. Ensure you provide the exact path to the dump file you are restoring, including the server name (if required).
