SSRS报告构建器和MySQL

Question

我有一份SSRS报告构建器报告。以下查询不会产生任何结果。但是，当我在SSRS之外运行此查询对我的MySQL数据库时，我得到了我想要的结果。

SELECT DISTINCT usr.user_name, COUNT(aud.user_id) AS audit_totals_total
FROM prover.aud_results_v AS aud
JOIN prover.user_profiles AS usr ON aud.user_id = usr.user_id
WHERE (aud.aud_date = @startdate AND aud.aud_time > '17:59:59' OR aud.aud_date = @enddate2 AND aud.aud_time < '06:00:00')

GROUP BY aud.user_id
ORDER BY usr.user_name
