Database .NET Free Download — Setup Guide and Quick Tour

Overview
Database .NET is a lightweight, portable Windows database management tool that supports many engines (SQL Server, MySQL, PostgreSQL, SQLite, Oracle, Firebird, Access, Excel, ODBC/OLEDB sources and more). It’s free for basic use, offers a single EXE (no install required), a table designer, data editor, SQL editor with autocomplete, export/import, schema scripting, and a simple SQL profiler — useful for quick tasks and multi-DB troubleshooting.

Before you begin

• Windows 7–11 compatible (32-bit and 64-bit builds available).
• Download only from trusted mirrors (official fishcodelib page or reputable download sites such as MajorGeeks, CNET, FileHippo).
• If connecting to server databases, ensure network access and correct credentials.
• Consider antivirus scan for the downloaded EXE.

Step 1 — Download

1. Go to a trusted source (example: MajorGeeks or the Database .NET entry in the Visual Studio Marketplace).
2. Choose the appropriate build (32-bit or 64-bit). File size typically ~10–50 MB depending on version.
3. Save the EXE to a folder (Database .NET is portable; no installer required).

Step 2 — First run & basic configuration

1. Double-click the EXE. If Windows SmartScreen or antivirus prompts appear, confirm you want to run it (only if downloaded from a trusted source).
2. The app opens with a left-side object navigator and central workspace. No initial configuration is required.

Step 3 — Create a connection (quick)

1. Click the New Connection or plus (+) icon.
2. Select provider/type (e.g., SQL Server, MySQL, SQLite, Access).
3. For file-based DBs (SQLite, Access, Excel) point to the file path. For server DBs enter host, port, database name, username, password.
4. Test Connection then Save. Connections show in the navigator.

Quick tour — main panels and tasks

• Object Navigator: browse servers, databases, schemas, tables, views, procedures.
• Table Designer: create/modify table columns, types, indexes.
• Data Editor: view and edit rows inline; supports filtering and sorting.
• SQL Editor: write and run queries with syntax highlighting, autocomplete, multiple tabs.
• Query Builder: visually compose joins and conditions (where available).
• Export/Import: export result sets to CSV, Excel, XML, TXT, SQL; import from CSV/Excel.
• Script Generator: generate CREATE/ALTER scripts for tables and other objects.
• SQL Profiler / Monitor: inspect and analyze running queries (basic profiling features).
• Code Manager & Favorites: save reusable queries and snippets.

Common tasks (step-by-step)

• Run a query: Open SQL Editor → type SQL → press Execute (F5 or Run button).
• Export results to CSV: After query, click Export → choose CSV → save.
• Add a row: Open table in Data Editor → click New Row → enter values → Save.
• Generate table DDL: Right-click table → Generate Script → copy or save SQL.

Tips & best practices

• Use the Test Connection button before saving credentials.
• For production servers prefer read-only accounts if only querying.
• Back up databases before running destructive scripts.
• Keep a copy of the portable EXE in a secure folder and version it if you rely on specific behavior.
• If you need advanced features or active community support, consider alternatives (DBeaver, HeidiSQL, DBeaver, SQL Server Management Studio for SQL Server).

Troubleshooting

• Connection failures: verify host/port, firewall rules, and that server accepts remote connections.
• Missing provider drivers: install the appropriate ODBC/OLE DB or database client if required (e.g., Oracle client).
• Crashes or stability issues: try another recent build from an official mirror or run as Administrator.

Security & licensing notes

• Database .NET is offered as freeware for basic usage; paid/pro versions or features may exist.
• Never store plaintext credentials in shared folders; use OS-level protections.
• Only download from trusted sites to avoid tampered binaries.

Wrap-up Database .NET is a fast, no-install, multi-database tool well suited for developers and admins who need a simple universal client on Windows. Download the appropriate EXE, add connections, and use the object browser, SQL editor, data editor, and export tools to manage and inspect databases quickly.
