- Around line 777-824: The test performs position-based assertions but the SQL
lacks an ORDER BY, so update both SqlTransform::new invocations (the ones
constructing t and t2) to include a deterministic ordering clause — e.g. append
"ORDER BY status_int NULLS LAST" to the query string used in SqlTransform::new
so rows are returned in a stable order for the assertions after
execute_blocking.
In `@docs/COLUMN_NAMING.md`:
- Around line 54-55: The example text incorrectly claims that "WHERE status =
'OK'" demonstrates explicit string-variant access; update the wording to clarify
this uses synthesized bare-column semantics and not direct variant access, and
replace or add the correct example showing explicit string variant access (e.g.,
use status__str = 'OK' or an explicit cast like CAST(status AS TEXT) depending
on supported syntax) so readers see the difference; edit the sentence around the
example and provide the explicit-variant example referencing the status__str
variant name.

Add ORDER BY for deterministic row ordering in position-based assertions.
The test uses positional assertions on SQL results without specifying ORDER BY, which makes it fragile to potential execution order changes. While single-source SELECTs typically preserve insertion order, this test file consistently uses ORDER BY in other assertion-based tests (e.g., lines 226, 262, 405) to ensure deterministic results.

| -- Get the string variant explicitly: | ||
| SELECT * FROM logs WHERE status = 'OK' |
There was a problem hiding this comment.
This example is not “explicit string variant” access.
WHERE status = 'OK' uses the synthesized bare column semantics, not direct status__str variant access. Please adjust wording to avoid confusion.
