SQL Union结果组类似于“LIKE”

标签： sql excel ms-access union

使用Access 2007，我正在尝试运行一个查询，该查询将一长串联合查询输出并组织到报表的数据列表中。该报告是我的主管传递给我的，我希望SQL只做腿部工作，这样我就可以导出到Excel文件然后复制粘贴。问题：

我使用的数据是从另一个部门从单独的Miscrosoft Excel导入的，而且职员不遵循基本的数据库规则，也没有改变系统的希望。 ＆＃34; LOSING_UNIT＆＃34;列有时包含多个示例（即一些LOSING_UNITS是＆＃34; A Trp＆＃34;其他是＆＃34; A Trp B Trp C Trp＆＃34;除了空格外没有逗号，分号或任何其他形式确定下一个单位）

如果可能的话，我需要查询执行类似于groupby的Like关系，以便包含＆＃34; A Trp＆＃34;成为一个完整，剩余一个等等（目前我的输出为

Title                       LOSING_UNIT                                  Total
Completed Directives        A TRP 3-71 CAV                               12
Delinquent Directives       A TRP 3-71 CAV                                2
Missing GUIC                A TRP 3-71 CAV                                2
Remaining Directives        A TRP 3-71 CAV                                8
Missing GUIC                A TRP 3-71 CAV B TRP 3-71 CAV C Co 3-71 CAV   1
Remaining Directives        A TRP 3-71 CAV B TRP 3-71 CAV C Co 3-71 CAV   1

如果这不可能，则选项2：能够按字符串的长度排序，以便所有单独的LOSING_UNITS出现在顶部，按字母顺序排列ORDERBY秒。我没有能够在没有生成＆＃34;聚合函数的情况下找到这样做的方法。错误。

Select 'Completed Directives' AS Title, LOSING_UNIT, Count(PSD_ID) AS Total

FROM [Lateral_Transfers_Closed_Canceled_LINKED]

WHERE (LOSING_PARENT_UIC = "WJJ4AA")
AND (STATUS = "Complete")
GROUP BY LOSING_UNIT
ORDER BY LOSING_UNIT

UNION

SELECT 'Remaining Directives', LOSING_UNIT, COUNT(PSD_ID)

FROM [Lateral_Transfers_LINKED] AS LT

WHERE (LOSING_PARENT_UIC = "WJJ4AA")
GROUP BY LOSING_UNIT
ORDER BY LOSING_UNIT

UNION

SELECT 'Delinquent Directives' AS Title,LOSING_UNIT, Count(PSD_ID) AS TOTAL
FROM [Lateral_Transfers_LINKED] AS LT
WHERE LT.SUSPENSE_DATE BETWEEN #1/01/2014# AND DATE()

GROUP BY LOSING_UNIT
ORDER BY LOSING_UNIT;

编辑：

为了更清楚一点，这里是我试图根据其他文章调整SQL的方法 SQL Query - Using Order By in UNION 

Select '' AS Title, LOSING_UNIT, '' AS Total
FROM(
Select 'Completed Directives', LOSING_UNIT, Count(PSD_ID)
FROM [Lateral_Transfers_Closed_Canceled_LINKED]
WHERE (LOSING_PARENT_UIC = "WJJ4AA")
AND (STATUS = "Complete")

UNION

SELECT 'Remaining Directives', LOSING_UNIT, COUNT(PSD_ID)
FROM [Lateral_Transfers_LINKED] AS LT
WHERE (LOSING_PARENT_UIC = "WJJ4AA")

UNION

SELECT 'Delinquent Directives' AS Title,LOSING_UNIT, Count(PSD_ID) AS TOTAL
FROM [Lateral_Transfers_LINKED] AS LT
WHERE LT.SUSPENSE_DATE BETWEEN #1/01/2014# AND DATE()
AND (LOSING_PARENT_UIC = "WJJ4AA")

UNION

SELECT 'Missing GUIC', LOSING_UNIT, Count(PSD_ID)
FROM [Lateral_Transfers_LINKED] AS LT
WHERE (LOSING_PARENT_UIC = "WJJ4AA")
AND ( GUIC Is Null OR GUIC = "Not Activated" )
AND LUIC Is NOT Null

UNION

SELECT 'Missing LUIC', LOSING_UNIT, COUNT(PSD_ID)
FROM [Lateral_Transfers_LINKED] AS LT
WHERE (LOSING_PARENT_UIC = "WJJ4AA")
AND LUIC Is Null
AND GUIC Is NOT Null

UNION 

SELECT 'On Hold', LOSING_UNIT, Count(PSD_ID)
FROM [Lateral_Transfers_LINKED] AS LT
WHERE (LOSING_PARENT_UIC = "WJJ4AA")
AND (LT.SERIAL_NUMBER  LIKE "Temp. Hold")
GROUP BY LOSING_UNIT
ORDER BY LOSING_UNIT)

GROUP BY LOSING_UNIT
ORDER BY MID(LOSING_UNIT, 1, 5), LOSING_UNIT;

我也尝试将聚合放入第一个SELECT而不改变结果。

创建一个表，其中包含一个字段，其中包含您要从LOSING_UNIT列中“分解”的所有值。我们称之为 ValuesToFind 。

然后您的查询如下：

select Count(PSD_ID), ValuesToFind.Value from 
[Lateral_Transfers_LINKED] LT
left join ValuesToFind
on LT.LOSING_UNIT LIKE '*' + ValuesToFind.Value + '*'
GROUP BY 
ValuesToFind.Value

显然添加了您想限制数据的过滤器。

另外，我建议使用Switch功能将各种字段解码为 Title 列，以便在一个位置控制映射逻辑。像

这样的东西 
  select 
    ValuesToFind.Value,
    Count(PSD_ID), 
    Switch(STATUS = "Complete", 'Completed Directives',
LT.SUSPENSE_DATE BETWEEN #1/01/2014# AND DATE(), 'Delinquent Directives',
GUIC Is Null OR GUIC = "Not Activated", 'Missing GUIC',
LUIC Is Null AND GUIC Is NOT Null, 'Missing LUIC',
LT.SERIAL_NUMBER  LIKE "Temp. Hold", 'On Hold',
1 =1, 'Remaining Directives') as Title
    from 
    [Lateral_Transfers_LINKED] LT
    left join ValuesToFind
        on LT.LOSING_UNIT LIKE '*' + ValuesToFind.Value + '*'
    GROUP BY 
        ValuesToFind.Value,
Switch(STATUS = "Complete", 'Completed Directives',
LT.SUSPENSE_DATE BETWEEN #1/01/2014# AND DATE(), 'Delinquent Directives',
GUIC Is Null OR GUIC = "Not Activated", 'Missing GUIC',
LUIC Is Null AND GUIC Is NOT Null, 'Missing LUIC',
LT.SERIAL_NUMBER  LIKE "Temp. Hold", 'On Hold',
1 =1, 'Remaining Directives')

更新：我看到你的已完成指令来自另一个表，由你来决定是否将你的两个表联合在一起，然后执行这个聚合，或者分别对每个表执行每个聚合，然后UNION就是结果。
