[archiewood]

• Prompts to install SQLtools and the correct driver if not installed
• Returns Query result in Side Panel
• Povides access to the SQLTools database explorer

SQLTools is not installed

Database Explorer

Inline Queries

File Queries

Chained Queries

Done

• Smoother connection
  • Read connection info from evidence settings (dont have the configure the connection in 2 places) Done for 1 configuration of Snowflake and BQ only - there is lots of tricky conditional logic to thing about here.
  • Don’t run the query and instead suggest the right driver if the SQLtools driver is not installed
• Chained queries (will currently fail) as it doesnt compile the SQL with caveat

Outstanding Issues

• Reading in settings from Evidence. This is a bunch of quite gnarly logic - maybe we should just make the user add the settings themselves.
• Chained queries are somewhat borked. I am reading in the compiled queries from the file system. They only run correctly if:
  • The user has saved the markdown page
  • The evidence server is running
  • The user has the page with the query in it open in the browser
• Codelens to pull up database in sidebar?
• Doesn't auto pick the connection if it exists (rather than the dropdown showing first time)
  • Though this only happens once per session, after which the connection is assumed
• Rigorous testing
• No DuckDB SQLTools driver - so the demo project is a bit crippled
