Question

当我在查询中添加以下条件时，它不再返回任何值。我不明白这一点，因为它涵盖了什么时候都没有价值提供给以下提示，应该可以正常工作。有什么想法吗？

(( A.EMPLID = :3 OR  A.EMPLID = :4 OR  A.EMPLID = :5 OR  A.EMPLID = :6 OR  
A.EMPLID = :7) OR (' ' = :3 AND ' ' = :4 AND ' ' = :5 AND ' ' = :6 AND ' ' 
= :7)) AND NVL( A.INVOICE_ID, ' ') LIKE DECODE (:8, ' ', '%', :8)
