Tables in Joins module in Developer Level 3 course

Hi,

I am getting an error with the `trade` table created by `init.q` as it is missing the `size` column that the code requests.

Hi @abstrphil

Can I advise that you start and stop your server by going to File -> Hub Control Panel then Stop Server and Start Server.

Run these cells again and let me know the output.

Many thanks,

Megan

  Hi Megan,
  
  Unfortunately, that didn’t fix it. The output was still the same.

On a separate note, in the Joins Exercises, the suggested solution for the third-last exercise throws up a type error as the `time` column is a minute type.

  Hi @abstrphil
  
  Is it okay if I access your server so I can view these errors for myself?
  
  Many thanks,

    Yes, sure, by all means!
    
    Feel free to leave critique of my code too if you spot anything!

Hi @abstrphil

I’m not sure what caused the size column to be removed from the trade table, but I renamed your course-advanced folder to course-advanced-old and installed a fresh version. That code should now run fine 🙂

If you have any further questions, please let me know!

Many thanks,

Megan
