The Ultimate Secret Of How to Read.FRM file

“There are two main ways to open or access a Read .FRM file:

  • Using MySQL Workbench

MySQL Workbench is a graphical user interface (GUI) tool that can be used to manage MySQL databases. To open an .FRM file in MySQL Workbench, follow these steps:

  1. Open MySQL Workbench.
  2. In the Object Browser, expand the Databases node.
  3. Right-click on the database that contains the .FRM file and select Open.
  4. In the Open File dialog box, select the .FRM file and click Open.

  • Using the MySQL command-line client

The MySQL command-line client can be used to access MySQL databases from the command line. To open an .FRM file in the MySQL command-line client, follow these steps:

  1. Open a command prompt.
  2. Navigate to the directory where the .FRM file is located.
  3. Type the following command:
mysql -u root -p < database_name > < frm_file_name

For example, to open the .FRM file my_table.frm in the database my_database, you would type the following command:

mysql -u root -p my_database < my_table.frm

Once you have opened the .FRM file, you can view its contents in the MySQL command-line client.

There are two main ways to read an .FRM file:

  • Using a text editor

.FRM files are binary files, so they cannot be opened directly with a text editor. However, you can use a text editor to view the contents of an .FRM file in hexadecimal format. To do this, open the .FRM file in a text editor and set the file’s encoding to “”Hexadecimal””.

  • Using a MySQL client application

MySQL client applications, such as MySQL Workbench and the MySQL command-line client, can be used to read the contents of an .FRM file. To do this, open the .FRM file in the MySQL client application and use the SHOW CREATE TABLE command to view the table’s structure.

Here is an example of the output of the SHOW CREATE TABLE command for an .FRM file:

CREATE TABLE `my_table` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(255) DEFAULT NULL,
  `email` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

This output shows the structure of the my_table table, including the table’s name, the fields in the table, and the data types of the fields.

Metadata that keeps track of InnoDB-related objects such as tablesindexes, and table columns. This metadata is physically located in the InnoDB system tablespace. For historical reasons, it overlaps to some degree with information stored in the .frm files.

Because the MySQL Enterprise Backup product always backs up the system tablespace, all backups include the contents of the data dictionary.

A file containing the metadata, such as the table definition, of a MySQL table.

For backups, you must always keep the full set of .frm files along with the backup data to be able to restore tables that are altered or dropped after the backup.

Although each InnoDB table has a .frm file, InnoDB maintains its own table metadata in the system tablespace.

.frm files are backed up by the MySQL Enterprise Backup product. These files must not be modified by an ALTER TABLE operation while the backup is taking place, which is why backups that include non-InnoDB tables perform an FLUSH TABLES WITH READ LOCK operation to freeze such activity while backing up .frm files. Restoring a backup can result in .frm files being created, changed, or removed to match the state of the database at the time of the backup.”
