在 SQL 或 SSRS 中查找一组记录中的字母
我有以下数据(我有更多行,这只是一个示例):
VALUE Location FLEET REGION
P Pocatello, ID 104 232
B Pocatello, ID 104 232
B Spokane, WA 107 232
B Spokane, WA 107 232
在报告服务或 MSSQL 中,我需要按队列进行分组。将其分组后,我希望它查看每个组包含哪些值。
如果该组包含值 P 和 B,则其生产 如果该组仅包含 B 则为 Reporting 如果该组包含 P,则其生产率
我希望从这个示例中得到的是最终返回的以下行。
VALUE LOCATION FLEET REGION
Production Pocatello,ID 104 232
Reporting Spokane, WAS 107 232
现在,SQL 查询报告了我的问题顶部的数据。我需要使用 MSSQL 或 SSRS 进行分组和计算,其中任何一个都可以工作,但是我该如何去做才能获得上面列出的数据。
谢谢!
I have the following data (I have a lot more rows this is just an example):
VALUE Location FLEET REGION
P Pocatello, ID 104 232
B Pocatello, ID 104 232
B Spokane, WA 107 232
B Spokane, WA 107 232
In either reporting services or MSSQL I need to group by fleet. Afer it is grouped I want it to see what values each group contains.
If the group contains values P and B then its Production
If the group contains B only then it is Reporting
If the group contains P then its Productivity
What I want from this example is the following rows to be returned in the end.
VALUE LOCATION FLEET REGION
Production Pocatello,ID 104 232
Reporting Spokane, WAS 107 232
Right now the SQL query reports the data at the top of my quesiton. I need to either do the grouping and calculation is MSSQL or SSRS either one will work but how do I go about doing it to get the data listed like I have right above.
Thanks!

您可以对其他列进行分组,并检查
case
语句中是否存在 ifP
或B
:这将打印:
You could group on the other columns, and check for the presence if
P
orB
in acase
statement:This prints:
如果没有表定义,就很难说。您的示例数据中已经有完整的重复项,这表明表上没有主键。每个车队的位置总是相同吗?那地区呢?如果这实际上是另一个连接表的查询的结果集,那么您应该提及这一点并包含各个表的表定义。
这是我对可能为您指明正确方向的最佳猜测:
这依赖于它们只是“价值”的两个可能值,否则不容易适应。
Without a table definition(s), it's hard to say. You already have a complete duplicate in your sample data, which indicates that there is no Primary Key on the table. Is the location for each fleet always the same? What about the region? If this is actually a result set from another query that is joining tables then you should mention that and include the table definitions for the individual tables.
Here's my best guess as to something that might point you in the right direction:
This relies on their only being two possible values for "value" and is not easily adaptable otherwise.
