我很难用这个where子句获得正确的结果。我知道这是一个瘫痪问题。有什么建议吗?
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)
谢谢!
结果的问题是指标2字段有时是空白的,它只返回Indictator 2字段中存在某些内容的记录。
这是查询:
PROC SQL;
CREATE TABLE COMPLAINT_DATA_0 as

a.INDICATOR2,
a.COMMITTEE_ACTION AS REVIEW_TYPE,
a.LEVEL_OF_EXCEPTION AS METHOD_RECD,

我认为你正在寻找这个:
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 )
使用括号将逻辑组合在一起。

避免检查NULL(从而避免需要OR ...
)的技巧是将NULL转换为可比较的值,如:
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')
;

或者您甚至可以避免使用OR :)。
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')
答案 3 :(得分:0)
是否需要查看d.ARCHIVE_STATUS('N','Y')的结果 或者(d.ARCHIVE_STATUS为Null)如果是这样,你可能只需将其改为看起来像这样
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
)
这样它只会评估('N','Y')中的d.ARCHIVE_STATUS对d.ARCHIVE_STATUS是否为空
