Question

我的工作中有一项任务是使用SQL Developer将不同表中的多个字段放到一个工作表中。我是一个SQL的菜鸟，但设法建立一些东西。看看我的输出告诉我，我内置的限制不起作用。简短说明如下。有人可以帮帮我吗？！在我的输出中，我仍然在ATINN字段中看到1006以外的值，其他值在BWTAR字段中为空。我做错了什么？

5个表链接在一起
对用户的限制（DMSTRAATL等）
对产品组的限制（006 *等）
对某些产品的限制
对产品类型的限制（HERB等）
对特定数据字段的限制（所有产品的atinn = 1006）
特定数据字段的重新排列（所有产品应该有bwtar =空）

Answer 1

AND 运算符的优先顺序高于 OR 。使查询易于阅读使用围绕过滤子句的大括号（）。

假设您要选择dmssap.mara.matkl中具有特定值的记录或dmssap.mara.matnr中的某些值，则可以使用这些块之间的大括号进行精确处理，如下所示。

AND (
(dmssap.mara.matkl) IN (
    '006*', '007120',    '007130',    '007140',    '007170',    
    '007180',    '007210',    '007220',    '007230',    
    '007250',    '007270',    '007280',    '007290',    
    '007300',    '007320',    '007340',    
    '007370',    '007380',    '007400',    '007420'
)
OR (dmssap.mara.matnr) IN (
    '000000010001767697',     '000000010001870117',     '000000010001870116',     '000000010001870115',    
    '000000010001870114',     '000000010001870113',     '000000010001870112'
)
)

Answer 2

WHERE (dmssap.mara.ernam) IN (
    'DMSTRAATL', 'V0342628', 'V0343809', 
    'V0336003', 'V0009830', 'V0309577', 'V0010144'
)
AND (dmssap.mara.matkl) IN (
    '006*', '007120',    '007130',    '007140',    '007170',    
    '007180',    '007210',    '007220',    '007230',    
    '007250',    '007270',    '007280',    '007290',    
    '007300',    '007320',    '007340',    
    '007370',    '007380',    '007400',    '007420'
)
OR (dmssap.mara.matnr) IN (
    '000000010001767697',     '000000010001870117',     '000000010001870116',     '000000010001870115',    
    '000000010001870114',     '000000010001870113',     '000000010001870112'
)
AND (dmssap.mara.mtart) IN ('HERB', 'HALB', 'ZSTP')
AND (dmssap.ausp.atinn) = '1006'
AND (dmssap.mbew.bwtar) IS NULL;

症结在你的WHERE陈述中。 WHERE语句中关键字的评估顺序为NOT - ＆gt; AND - ＆gt; OR

你似乎想要的是这个：

WHERE (dmssap.mara.ernam) IN (
    'DMSTRAATL', 'V0342628', 'V0343809', 
    'V0336003', 'V0009830', 'V0309577', 'V0010144'
)
AND (dmssap.mara.matkl) IN ((
    '006*', '007120',    '007130',    '007140',    '007170',    
    '007180',    '007210',    '007220',    '007230',    
    '007250',    '007270',    '007280',    '007290',    
    '007300',    '007320',    '007340',    
    '007370',    '007380',    '007400',    '007420'
)
OR (dmssap.mara.matnr) IN (
    '000000010001767697',     '000000010001870117',     '000000010001870116',     '000000010001870115',    
    '000000010001870114',     '000000010001870113',     '000000010001870112'
))
AND (dmssap.mara.mtart) IN ('HERB', 'HALB', 'ZSTP')
AND (dmssap.ausp.atinn) = '1006'
AND (dmssap.mbew.bwtar) IS NULL;

注意AND

上OR的两个额外括号

SQL Developer和OR语句
