From initiating CRUD operations to optimizing table performance, we cover it all. We also spotlight dbForge Studio for MySQL, a feature-rich IDE that simplifies your interactions with MyISAM tables and databases. Whether you're a seasoned DBA or a developer looking to sharpen your database skills, this article serves as your go-to resource for understanding MyISAM clients and maximizing their capabilities.

### What is a MyISAM client?

A MyISAM client refers to a specialized application or module designed to interact with the MyISAM database storage engine. Its primary function is to facilitate essential database operations such as creating, reading, updating, and deleting data (commonly referred to as CRUD operations) through specific protocols, APIs, or query languages.

In the context of MyISAM, it's important to note that we are essentially referring to a [MySQL/MariaDB client](https://www.devart.com/dbforge/mysql/studio/), as the MyISAM storage engine is an integral part of these database management systems. A MyISAM client plays a pivotal role in initiating database management processes, sending queries to databases, and handling subsequent responses.

In simpler terms, any MyISAM client serves as the interface that allows users to interact with MySQL/MariaDB. There is a wide range of available solutions catering to different needs, including lightweight command line utilities like **myisamchk**, versatile options like the MySQL Command-Line Client, and feature-rich IDEs based on graphical user interfaces, such as MySQL Workbench or dbForge Studio for MySQL.

The choice of the right client largely depends on user preferences, the specific work environment, and the tasks they need to accomplish.

### How it works: a MyISAM client in action

To better understand the functionality of a MyISAM client, let's delve into a practical scenario where a user needs to compose and execute a query against the database and subsequently retrieve the results. Whether you opt for a command line or GUI client, the process unfolds as follows:

**Step 1: Connection Setup**

The client [initiates a connection to a MySQL/MariaDB server](https://www.devart.com/dbforge/mysql/studio/database-connections.html) using the necessary library or connector. During this setup, it provides authentication credentials and specifies the database to be accessed.

**Step 2: Query Submission**

The client sends SQL queries to the MySQL/MariaDB server, utilizing the appropriate database engine—in our case, MyISAM.

_Note: Modern GUI-based database clients, like dbForge Studio for MySQL and MariaDB, enhance query writing by offering essential features such as code auto-completion, formatting, debugging, code snippet libraries, and visual query builders for constructing intricate queries through diagrams._

**Step 3: Query Execution**

The database system takes charge of parsing and executing the SQL query. When the query involves a table managed by the MyISAM storage engine, MyISAM handles the data and its storage particulars.

**Step 4: Result Retrieval**

Upon completing query processing, the results are transmitted back to the client. The client then handles these results as needed—whether it's displaying them to the user or employing them for further operations.

**Step 5: Connection Closure**

Once the interaction is finished, the client responsibly closes the connection.

Throughout this process, it's essential to note that the client does not directly engage with MyISAM or any other storage engines. Instead, it interacts with the MySQL/MariaDB server, which, in turn, utilizes MyISAM to manage data at its level.

### dbForge Studio for MySQL and MariaDB as the MyISAM client

dbForge Studio for MySQL that is also a viable [MariaDB tool](https://www.devart.com/dbforge/mysql/studio/mariadb-gui-client.html) offers full support for all MySQL storage engines, including MyISAM, and a user-friendly graphical interface that simplifies interactions with MyISAM tables. The functionality of the Studio makes it the common choice for professionals who prefer GUI tools over command line utilities.

It includes options available in the **myisamchk** utility and [provides many more features to cover all database-related tasks on MySQL and MariaDB](https://www.devart.com/dbforge/mysql/studio/features.html), no matter which storage engine those databases use.

Speaking of MyISAM tables, it is worth mentioning some basic operations.

#### Check what storage engine is used in the database

In dbForge Studio for MySQL, you can check the storage engine of the current database in a couple of clicks. Select the database in Database Explorer, right-click the necessary table, and select **Properties** from the shortcut menu. The output will present the information of the database engine among other data.

![Check storage engine](https://2988006611-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FSsmexDFPv2xG2OTyO5yV%2Fuploads%2Fgit-blob-f984ab8a520de51058f6e2ddea366b9b5667cf5e%2Fcheckengine.png?alt=media)

#### Convert a table from InnoDB to MyISAM (and vice versa)

If you need to switch between database engines for some tables, you can use the standard ALTER TABLE command. dbForge Studio for MySQL allows executing SQL queries directly against the database.

To convert an InnoDB table to MyISAM, use the following command:

ALTER TABLE database\_name.table\_name ENGINE=MyISAM;

_Img 1 – InnoDB, img 2 – MyISAM_

The same ALTER TABLE command serves in the opposite situation where you want to convert MyISAM tables to InnoDB. You will need to specify ENGINE=InnoDB in that case.

MyISAM does not support foreign key constraints that are supported by InnoDB. In case you want to convert an InnoDB table having foreign keys into MyISAM, you will encounter an error. Make sure to drop those constraints before converting. There are more [differences between MyISAM and InnoDB](https://blog.devart.com/myisam-vs-innodb.html) that should be considered when you deal with these two storage engines.

#### Optimize MyISAM tables

The primary function of myisamchk is to check, optimize, and repair MyISAM tables. This is crucial because frequent CRUD operations (CREATE, READ, DELETE, UPDATE) can lead to table corruption and a gradual decline in performance over time. dbForge Studio for MySQL includes [a table maintenance tool](https://www.devart.com/dbforge/mysql/studio/optimize-mysql-table.html) that simplifies the process of identifying, analyzing, optimizing, and repairing tables.

To locate tables that require the administrator's attention, you can run the standard command in dbForge Studio for MySQL:

SHOW TABLE STATUS LIKE table\_name;

This command provides detailed information about the table properties, including the total space occupied by the table and the total unused space (Data\_length and Data\_free columns, respectively). This helps users pinpoint tables that may be consuming excessive space and may be corrupted.

![showtablestatus](https://2988006611-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FSsmexDFPv2xG2OTyO5yV%2Fuploads%2Fgit-blob-38a689711417cfb168cae885a701e504ee7cc0df%2Fshowtablestatus.png?alt=media)

This way, users can identify those tables that may take up too much space and be corrupted.

After detecting the MyISAM tables that require maintenance, you can apply the Studio’s integrated table maintenance tool to those tables to fix the issues. To launch it, right-click the necessary table in Database Explorer and select **Table Maintenance**.
