    1. COYou should move that code to classes and probably execute it in a background thread. Anyway, this error typically arises when you try to remove rows without actually decreasing the number of rows as provided by the table view's data source. Are you actually removing data when you remove the rows? If you're not deleting any rows, can you provide your table view data source implementation?

Guidance
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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
