    1. COCan you clarify if you are talking about running stuff in the interactive shell vs from a file, or talking about running something vs an `import`?

    2. COPerhaps if you detailed what you would do with the information, we can help find a good solution.

    3. COThanks for clarifying. This would be difficult to implement, and confusing for your users. Can you explain why you want this and what you'll do with it? There might be a better way.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
