Known Issue: query parameters don't show when statement has special characters
Problem
SQL queries/statements with special characters in comments (or maybe elsewhere?) will fail in a way that the query does not produce any results. This applies for characters like è, é, ä, ü, etc.
For example:
SELECT Name, Population
FROM Country
-- sélectionner uniquement les pays du continent donné
WHERE Continent = :Continent
Solution
Please avoid special characters in SQL statement. Although this looks like it would be a simple fix, it is technically not as trivial as one might think.
