the count statement against "{from}" returned no readable count, so the grid has no total for this query and will scroll open-ended rather than show the page size as the whole. This is an engine or driver result-shape problem, not a query problem.

Identifier

source.duckdb.count.unreadable

Raised by

The grid (core)

Since

1.69.0

What happened

The count query ran and its result could not be read as a number. The total is left absent rather than defaulting to the page length, so the grid scrolls open-ended.

The fix

A driver returning counts in an unexpected shape is the cause; check the driver version.
