This issue sadly still presists. The rowcount is now correct, but the content is still empty.
To clarify in case 3/4 if the table contains numerical values it works, but the results return empty strings for strings and text.
Same for the last two cases, the results are empty for strings/text and numerical values cause a FormatException. I see that the commit https://github.com/MariaDB/mariadb-connector-odbc/commit/bfb78c0 checks the for the correct rowcount but not the content.
Any ideas what could be causing this?
