なぜ同じデータセットからのクエリが私に別の結果を与えるのですか？

Question

私は基本的にどのように異なる結果セットを生成する同じ条件で同じクエリを理解できないのですか？私がやっているすべてはちょうどアモンサイズによって

--First query 
select count(distinct controlno) 
    FROM CatalyticWindEQ 
    WHERE EffectiveDate >='05-01-2016' AND EffectiveDate <= EOMONTH(GETDATE()) 
    AND LineName = 'Earthquake' 
    AND Underwriter <> 'Batcheller, Jerry' 
    AND DisplayStatus IN ('Bound','Bound - Issued') 
    and description IN ('New Business' 
         ,'Renewal' 
         ,'Rewrite')

私はここで何が欠けていますか？ そして違いを生むレコードを見つけるにはどうすればいいですか？

Answer 1

私が見ていることから、できることは最高です。そのようなことが私に起こったとき、私は第2の要求で複数のカテゴリに現れたが、より一般的な要求によって排除されたレコードを複製しました。
