Tools for Managing MySQL and MariaDB Databases: Which One to Choose and How to Get Started

You want to download a copy of your website’s database, check a table or import data during a migration. You open your hosting panel and see names such as MySQL, MariaDB and phpMyAdmin. Do you need to install something? Do you need to know how to code?

For many common tasks, a visual tool and a few basic skills are enough. In this guide, we compare phpMyAdmin, DBeaver, HeidiSQL and Adminer, explain what each one is for and show you how to get started if your website is hosted at miHosting.

Before choosing: MySQL and MariaDB are not the programs you use to connect

MySQL and MariaDB are systems that store and organize data. A website can use them to store posts, users, settings or orders. The data is arranged in tables: columns represent fields and rows contain records.

phpMyAdmin and DBeaver are tools that let you work with that data. Switching tools does not change your database engine or migrate your website.

MySQL and MariaDB share many features, but their versions and capabilities have evolved separately. It is therefore a good idea to choose a tool that is compatible with your hosting service’s database engine and version.

You should also distinguish between two ways to connect:

  • In a browser: you use a tool hosted on a server, such as phpMyAdmin.
  • On your computer: you install a client such as DBeaver or HeidiSQL and configure a connection to the server.

The second option requires your hosting service to allow that connection, or another authorized method such as an SSH tunnel. Installing a program does not by itself enable remote access.

Quick comparison: which tool is right for you?

ToolHow you use itWhen to choose itWhat to keep in mind
phpMyAdminIn a browserOccasional queries and exports from your hosting panelImports may be limited by server settings
DBeaver CommunityDesktop application for Windows, macOS and LinuxFrequent work and multiple connectionsYou need to configure access and choose the right driver
HeidiSQLDesktop application, with versions for Windows, Linux and macOSFrequent table browsing and editingCheck the availability and requirements of the version for your system
AdminerWeb application distributed as a PHP fileTest environments and occasional tasksIt needs to be installed, secured and maintained

All four options have free versions. If you are getting started with a hosting account, we recommend using phpMyAdmin first if it is available in your control panel. If you manage several websites or query data frequently, consider a desktop client.

1. phpMyAdmin: a starting point for managing your website’s database

phpMyAdmin lets you administer MySQL and MariaDB from a browser. It includes tools to browse tables, search records, run SQL and import or export data.

Its main advantage for beginners is convenience: if your hosting provider includes it in the control panel, you can use it without installing an application on your computer.

A practical example: you are about to update your website and want to save a copy of its database first. You select the correct database, open the export tab and download an SQL file containing its structure and data.

miHosting’s guide to backing up your hosting service explains how to access phpMyAdmin from DirectAdmin and export a database.

Keep its most common limitation in mind: a large import may exceed the upload size or execution time allowed by the server. If that happens, ask support about another method before trying again, since a failed attempt may have imported some of the content.

2. DBeaver Community: for working with multiple databases

DBeaver Community is a free, open-source tool that supports MySQL, MariaDB and other database engines. It is available for Windows, macOS and Linux.

It lets you organize connections, browse tables and use data and SQL editors. It may be a good fit if you manage several websites or switch between a test database and a production database.

A practical example: you maintain three projects and need to check their tables every week. Saving the connections in one application may be more convenient than opening each hosting panel separately.

Initial setup requires a little more attention. You need to select the right database engine and enter your access details. A driver is the component that lets the program communicate with the database; DBeaver may ask you to download one during setup.

Start by querying data and learn how the application saves changes before editing a database that is in use. You can download it from the official DBeaver Community page.

3. HeidiSQL: a practical option for browsing tables and running SQL

HeidiSQL is a free, open-source tool for working with MySQL, MariaDB and other systems. It includes data editing, SQL queries, exports and imports.

It is worth trying if you want to work regularly from a desktop application. Its website offers versions for Windows, Linux and macOS; check the requirements for the download that matches your computer.

A practical example: you maintain a custom application and need to filter records, review their contents and export results for analysis. HeidiSQL brings those tasks together in one interface.

As with DBeaver, you will need authorized access to the server. Also, seeing a table in a grid does not make it a separate spreadsheet: a saved change may affect your website immediately.

4. Adminer: a web-based alternative for specific needs

Adminer lets you administer MySQL, MariaDB and other database engines through an application distributed as a PHP file. It includes data queries and editing, SQL execution and export.

It can be useful in a development environment or on a server you manage when you need a web interface for a specific task. Check that your hosting service meets its requirements and allows you to use it.

Its small size does not remove the need for maintenance. Adminer recommends restricting access, keeping it up to date and removing it when it is no longer needed.

If you already have phpMyAdmin at miHosting and it meets your needs, you usually do not need to add another web-based tool. For someone just starting out, using the access already available is often simpler.

How to get started with your database at miHosting

1. Identify the database your website uses

Open your hosting control panel and find the database section. Check the database name and its associated user. If you have several installations, make sure you choose the right one.

In WordPress, the wp-config.php file contains the connection settings. You can check them if you have access to the files, but do not share that file or publish screenshots that reveal the password.

2. Save a copy before changing data

In phpMyAdmin, the usual process is:

  1. Select your website’s database.
  2. Open Export.
  3. Choose SQL and check that the structure and data for the necessary tables are included.
  4. Download the file and save it somewhere private, outside the website’s public folder.

An SQL export backs up the database. To restore a complete website, you also need its files, such as images, themes, plugins and configuration. You can follow both steps in miHosting’s hosting backup guide.

If your website receives orders or registrations while the copy is being made, you may need to coordinate the backup so the data is consistent. Downloading a file alone also does not prove that it can be restored: test it in a staging environment when possible.

3. Start with read-only operations

Browse the tables, review their columns and use filters to find records. You can learn a lot without changing data.

If you want to try SQL, this query shows the version reported by the server:

SELECT VERSION();

To query an example table named products, you could use:

SELECT id, name
FROM products
LIMIT 10;

The second query will only work if that table and those columns exist. SELECT reads information, and LIMIT 10 limits the output to ten rows; it does not guarantee that a complex query will use few resources.

4. Configure a desktop client only if you need one

To connect DBeaver or HeidiSQL, you will need these details:

DetailWhat to enter
EngineMySQL or MariaDB, depending on your service
Server or hostThe address provided for database access
PortThe one configured by your provider; 3306 is commonly used
DatabaseIts full name, including any prefix
Username and passwordThe database credentials
Security and accessAny TLS, authorized IP or SSH requirements

Do not copy localhost from your website’s configuration without checking it. On your computer, that address points to your own machine, not the hosting server.

Before setting up the connection, confirm with miHosting whether your service allows remote access and which method you should use. Database credentials may differ from your control panel or client area credentials.

Common problems and what to check first

ProblemFirst check
You see “Access denied”Check the username, password, permissions and authorized connection source
The connection times outCheck the host, port and whether remote access is available
The SQL file does not import completelyCheck the upload limit, execution time and status of the previous import
You see a collation or syntax errorCheck compatibility between the source and destination versions
You cannot find the databaseCheck the account, full database name and user permissions

If you ask for help, provide the tool’s name, the error message and the operation you were performing. Avoid sending passwords or database dumps that contain personal data through channels not intended for them.

Habits that help you avoid MySQL or MariaDB mistakes

Work on a test copy when making important changes. Clearly label test and production connections, and use a read-only user when you only need to view information.

Before importing, check what the SQL file contains: it may include instructions to delete and recreate tables. Also, avoid running a direct text replacement across an entire WordPress database unless you use a tool that handles serialized data correctly; a simple replacement can break its format.

Do not run repair or optimization operations as a routine. If your website is slow, identify the cause first; changing database clients does not speed up the queries your application runs.

Which tool should you choose for your website?

If you are just getting started, phpMyAdmin is a good first step for browsing tables and exporting databases from your control panel. For more frequent work, DBeaver Community and HeidiSQL offer desktop alternatives. Adminer is better suited to a specific need when you can secure and maintain its installation.

If your project needs a database, you can review miHosting’s hosting options. If you are already a customer, start with the tools in your control panel and confirm your service’s terms before configuring external connections. The best choice is the one that lets you complete your task clearly and recover your data if something goes wrong.
