A Windows workstation can query a remote database without hosting one itself. The MariaDB client supplies the SQL shell, and its official Windows installer can install the tools without creating a local database instance.
MariaDB distributes the client in the MariaDB Server MSI package. Disabling Database instance skips local database initialization and service creation; the package can still place server binaries on disk.
Installation requires administrator approval. The MariaDB Command Prompt shortcut adds the installed bin directory to that shell's PATH, so no system-wide environment change is needed to run the client.
Steps to install MariaDB client on Windows:
- Open the official MariaDB Foundation download page in a browser.
https://mariadb.org/download/
- Select a stable MariaDB Server release from the version menu.
The pictured release is 11.8.9; maintenance version numbers change over time. Entries marked Preview or RC are prereleases.
- Download the Windows x86_64 MSI Package with the Download button.
The filename ends in winx64.msi. Connector/C is a development library, not a replacement for the interactive SQL client.
- Open the downloaded mariadb-<version>-winx64.msi file.

- Click Next on the setup wizard's welcome screen.

- Select I accept the terms in the License Agreement if you accept the license.

- Click Next to reach Custom Setup.

- Set Database instance to Entire feature will be unavailable using its feature-icon menu.
Leaving Database instance enabled creates a local database and can register a Windows service. Its red X excludes that setup while leaving Client Programs installed.
- Click Next with Client Programs selected and Database instance disabled.
The MariaDB Server parent feature remains selected. HeidiSQL is an optional graphical client; the other default features can remain selected for this installation.
- Click Install to install the selected features.
Setup writes to the protected installation directory and needs administrator approval.
- Click Yes at the User Account Control prompt for MariaDB Installer.
Approval permits changes to the computer. The downloaded installer should show MariaDB USA, Inc. as its verified publisher.
- Click Finish when the setup wizard reports completion.

- Open Command Prompt (MariaDB 11.8 (x64)) from a Start search for MariaDB.
The shortcut name includes the installed version. Its PATH applies to this shell; a persistent change is optional.

C:\Windows\System32>mariadb --version mariadb from 11.8.9-MariaDB, client 15.2 for Win64 (AMD64), source revision bf9193a939f515e95dd8def1a5468088c91cede6
The version line confirms the client runs without contacting a database server. An unrecognized-command error usually means a regular shell was opened instead of the MariaDB shortcut. mysql.exe is also available as an alternate client binary on Windows.
