Tips

1. Instead of using VS Code’s built-in Copy Cell or + Code / Add Code Cell, I recommend using Duplicate Cell with Metadata. This action copies not only the cell content, but also all associated metadata—such as database connection settings and ResultSet decoration options—so you can add a new cell without reconfiguring these settings.

2. You can specify a default connection definition each time you add a new SQL cell to the notebook

Recommended Extensions
