Question

我需要一些关于我写的SELECT声明的帮助。

声明如下：

SELECT  DISTINCT MANDT, PATH301 
FROM    NC301B
WHERE   EDIPROC like 'P30_'
    AND (LF301M > 0) 
    AND (MANDT LIKE '011')
    AND (PATH301 NOT LIKE '%:\saptemp%')
    AND (PATH301 NOT LIKE '%:\SAPTEMP%')  
    AND (PATH301 NOT LIKE '%usr%')  
    AND (PATH301 NOT LIKE '%:\Windows%')
    AND (PATH301 NOT LIKE '%PKV_DAV%')
    AND (PATH301 NOT LIKE '%pkv_dav%');

现在我需要检查额外的MANDT - ＆gt; MANDT LIKE '012'

我的问题是，当我将OR (MANDT LIKE '012')行添加到语句时输出不正确。

我的想法是：

SELECT  DISTINCT MANDT, PATH301 
FROM    NC301B
WHERE   EDIPROC like 'P30_'
    AND (LF301M > 0) 
    AND (MANDT LIKE '011')
    OR (MANDT LIKE '012')
    AND (PATH301 NOT LIKE '%:\saptemp%')
    AND (PATH301 NOT LIKE '%:\SAPTEMP%')  
    AND (PATH301 NOT LIKE '%usr%')  
    AND (PATH301 NOT LIKE '%:\Windows%')
    AND (PATH301 NOT LIKE '%PKV_DAV%')
    AND (PATH301 NOT LIKE '%pkv_dav%');

是否可以在一个语句中检查两个或更多MANDT个值就像我在我的例子中所做的那样

谢谢！

Answer 1

你需要注意括号，试试这个

SELECT  DISTINCT MANDT, PATH301  FROM    NC301B WHERE   EDIPROC like
'P30_'
    AND (LF301M > 0) 
     AND (MANDT LIKE '011' OR MANDT LIKE '012')
     AND (PATH301 NOT LIKE '%:\saptemp%')
     AND (PATH301 NOT LIKE '%:\SAPTEMP%')  
     AND (PATH301 NOT LIKE '%usr%')  
     AND (PATH301 NOT LIKE '%:\Windows%')
     AND (PATH301 NOT LIKE '%PKV_DAV%')
     AND (PATH301 NOT LIKE '%pkv_dav%');

Answer 2

在MANDT上的两张支票上放置括号：

SELECT  DISTINCT MANDT, PATH301 
FROM    NC301B
WHERE   EDIPROC LIKE 'P30_' AND
    (LF301M > 0) AND
    ((MANDT LIKE '011') OR (MANDT LIKE '012')) AND
    (PATH301 NOT LIKE '%:\saptemp%') AND
    (PATH301 NOT LIKE '%:\SAPTEMP%') AND
    (PATH301 NOT LIKE '%usr%') AND
    (PATH301 NOT LIKE '%:\Windows%') AND
    (PATH301 NOT LIKE '%PKV_DAV%') AND
    (PATH301 NOT LIKE '%pkv_dav%');

Answer 3

您需要使用括号对两个谓词进行分组，因为and的优先级高于or：

...
AND ( (MANDT LIKE '011') OR (MANDT LIKE '012') ) 
...

Answer 4

您可以使用REGEXP_LIKE，因为您没有在＆＃39; 011＆＃39;和＆＃39; 012＆＃39;，您可以使用IN Condition：

SELECT DISTINCT MANDT, PATH301
  FROM NC301B
 WHERE EDIPROC LIKE 'P30_' 
   AND LF301M > 0
   AND MANDT IN ('011','012')
   AND NOT regexp_like(path301, '(:\\saptemp|:\\SAPTEMP|usr|:\\Windows|PKV_DAV|pkv_dav)')

由于：

默认区分大小写由NLS_SORT参数的值确定。

你可以在regexp_like中使用第三个参数：

＆＃39;我＆＃39;指定不区分大小写的匹配。

＆＃39; C＆＃39;指定区分大小写的匹配。
