このwhere句で正しい結果を得るのに苦労しています。私はそれが括弧の問題であることを知っています。助言がありますか？

WHERE a.EVENT_DATE Between &trend_dt  And &enddate  
AND a.INDICATOR Not In ('INQUIRY (NOS)','PCC') 
And a.INDICATOR2 Not In ('CAT-NA','INQUIRY (NOS)') 
And d.ACTIVE In ('C','F') 
And d.ARCHIVE_STATUS in ('N','Y') 
Or (d.ARCHIVE_STATUS Is Null)

ありがとう！

結果の問題は、Indicator 2 フィールドが空白になることがあり、Indictator 2 フィールドに何かがあるレコードのみを返すことです。

これはクエリです：

CREATE TABLE COMPLAINT_DATA_0 as
SELECT 
a.EVENT_DATE,

a.INDICATOR2,

私はあなたがこれを探していると思います：

WHERE a.EVENT_DATE Between &trend_dt  And &enddate  
AND a.INDICATOR Not In ('INQUIRY (NOS)','PCC') 
And a.INDICATOR2 Not In ('CAT-NA','INQUIRY (NOS)') 
And d.ACTIVE In ('C','F') 
And ( d.ARCHIVE_STATUS in ('N','Y') Or d.ARCHIVE_STATUS Is Null )

括弧を使用してロジックをグループ化します。

NULL のチェックを回避する (したがって の必要性を回避するOR ...) ための秘訣は、次のように NULL を同等の値に変換することです。

WHERE a.EVENT_DATE BETWEEN &trend_dt AND &enddate  
AND a.INDICATOR NOT IN ('INQUIRY (NOS)','PCC') 
AND a.INDICATOR2 NOT IN ('CAT-NA','INQUIRY (NOS)') 
AND d.ACTIVE IN ('C','F') 
AND COALESCE(d.ARCHIVE_STATUS, 'N') IN ('N','Y') 
   ;

または、OR の使用を避けることもできます :)

WHERE a.EVENT_DATE Between &trend_dt  And &enddate  
AND a.INDICATOR Not In ('INQUIRY (NOS)','PCC') 
And a.INDICATOR2 Not In ('CAT-NA','INQUIRY (NOS)') 
And d.ACTIVE In ('C','F') 
And COALESCE(d.ARCHIVE_STATUS,'-1') in ('N','Y','-1')

d.ARCHIVE_STATUS in ('N','Y') Or (d.ARCHIVE_STATUS Is Null) の結果を表示する必要がある場合は、おそらく次のように変更する必要があります

WHERE a.EVENT_DATE Between &trend_dt  And &enddate  
AND a.INDICATOR Not In ('INQUIRY (NOS)','PCC') 
And a.INDICATOR2 Not In ('CAT-NA','INQUIRY (NOS)') 
And d.ACTIVE In ('C','F') 
And (
      d.ARCHIVE_STATUS in ('N','Y') 
      Or 
      d.ARCHIVE_STATUS Is Null
    )

このように、d.ARCHIVE_STATUS Is Null に対して ('N','Y') の d.ARCHIVE_STATUS のみを評価します。
