A Python desktop application for connecting to SQL Server databases and viewing their schema.

• Multiple Authentication Types:

  • SQL Server Authentication (username/password)
  • Windows Authentication (Trusted Connection)
  • Azure Active Directory Password
  • Azure Active Directory Integrated
  • Azure Active Directory Interactive (MFA/2-Factor)
  • Azure Active Directory Service Principal

• Schema Browsing:

  • View all databases on the server
  • Browse tables, views, stored procedures, and functions
  • View column details with data types, nullability, and key information
  • View index information for tables
  • View parameters for stored procedures and functions

• Python 3.8 or later
• SQL Server ODBC Driver (ODBC Driver 17 or 18 for SQL Server recommended)
• For Azure AD authentication: Azure AD-enabled SQL Server or Azure SQL Database

1. Clone or download this repository:

   cd testcode

2. Install the required Python packages:

   pip install -r requirements.txt

3. Ensure you have the SQL Server ODBC driver installed:

   • Windows: Download from Microsoft ODBC Driver for SQL Server
   • macOS: brew install msodbcsql18
   • Linux: Follow the Linux installation guide

1. Run the application:

   python main.py

2. Connect to a SQL Server:

   • Go to File > Connect... or use the menu
   • Enter your server name (e.g., localhost, myserver.database.windows.net)
   • Select the authentication type
   • Enter credentials as required
   • Click Connect

3. Browse the schema:

   • Select a database from the dropdown
   • Expand the tree to view tables, views, procedures, and functions
   • Click on an object to view its details in the right panel

Standard SQL Server login with username and password.

Uses your Windows credentials for trusted connections. No username/password required.

Azure Active Directory authentication with username and password. Use for Azure SQL Database with AAD integration.

Uses your current Windows Azure AD credentials. Requires domain-joined machine with Azure AD.

Supports Multi-Factor Authentication. A browser window will open for interactive login. Best for users with MFA enabled.

Authentication using an Azure AD application. Requires:

• Client ID (Application ID)
• Client Secret
• Tenant ID (optional for some scenarios)

If you see "Driver not found" errors, ensure the ODBC driver is installed:

# Check available drivers (Python)
import pyodbc
print(pyodbc.drivers())

• Ensure your SQL Server/Azure SQL supports Azure AD authentication
• For interactive authentication, allow the browser popup
• For service principal, verify the client ID and secret are correct

Increase the connection timeout in the connection dialog options if connecting to a remote server.
