如何在Visual Studio Code的.NET Interactive Notebook中查询PostgreSQL数据库？

Got it, replicating your SQL Server workflow for PostgreSQL in VS Code using .NET Interactive Notebooks is straightforward—here’s the step-by-step breakdown:

• Install the required extension (same as with SQL Server): Make sure you have the .NET Interactive Notebooks extension installed in VS Code. If not, grab it from the Extensions marketplace.
• Create a blank notebook: Press Ctrl+P, then select .NET Interactive: Create new blank notebook to generate a notebook with the .dib file extension.
• Set up the PostgreSQL connection in a C# cell:
  1. First, load the PostgreSQL NuGet package for .NET Interactive by running this line:

     #r "nuget:Microsoft.DotNet.Interactive.PostgreSQL,*-*"
     

  2. Next, establish a connection to your PostgreSQL database using the #!connect magic command. Replace the placeholder values with your actual database credentials:

     #!connect postgresql "Host=your-db-host;Username=your-username;Password=your-password;Database=your-target-db" --kernel-name postgres-db
     

     The --kernel-name flag is optional but useful if you want to name your connection for clarity (you can reference it later if needed).
• Run PostgreSQL queries in a SQL cell:
  Add a new cell, switch its kernel to SQL (.NET Interactive) (it should automatically associate with your PostgreSQL connection if you set it up correctly), then write and execute your PostgreSQL-specific SQL. For example:

  SELECT * FROM your_table LIMIT 10;
  

That’s all! The workflow mirrors your SQL Server setup—just swapped out the NuGet package and connection command to target PostgreSQL instead.
