SELECT CASE WHEN quantity IS NULL THEN NULL ELSE repeat(' ', greatest(quantity-65,0)::integer) END AS result FROM inputWritten for this dialect; not run here.

Same rows from the calculation and from the SQL in DuckDB.
Where a naive translation goes wrong
- Replacing SPACE with repeat(' ', quantity::integer) changes the shown values or null handling.
Naive SQL
SELECT repeat(' ', quantity::integer) AS result FROM inputresult null Matches the calculation
SELECT CASE WHEN quantity IS NULL THEN NULL ELSE repeat(' ', greatest(quantity-65,0)::integer) END AS result FROM inputresult null
