SQL Server 2008: Joining results of STORED PROCEDURE (dynamic columns) with results of a SELECT statement
提问by hendridm
I have results that are generated by this stored procedure.
我有这个存储过程生成的结果。
I want to join these results with data in another table. I've seen various examples of doing this be creating a temporary tableand inserting into it, however, this would not be ideal as the stored procedure returns many dynamic columnswhich are subject to change. Is there a way to join them dynamically?
我想将这些结果与另一个表中的数据连接起来。我已经看到这样做的各种示例是创建一个临时表并将其插入其中，但是，这并不理想，因为存储过程返回许多可能会发生变化的动态列。有没有办法动态加入它们？
Example scenario:
示例场景：
Stored Procedure Returns This:
存储过程返回这个：
EXEC uspGetProductCategories
products_id | products_model | Leather Seats | Heated Seats | Tapedeck | Heater | Hybrid | Sunroof | Cruise Control
===================================================================================================================
100 | Saturn Vue | N | N | Y | N | N | N | N
200 | Toyota Pruis | Y | N | N | Y | Y | N | N
300 | Ford Focus | N | N | N | Y | N | N | Y
I want to JOIN it with a SQL query that generates something like:
我想用一个生成如下内容的 SQL 查询来加入它：
SELECT * FROM Products_Detail
products_id | manufacturer | purchaser | pay_type
=================================================
100 | GM | GREG | P
200 | TOYT | SAM | P
300 | FORD | GREG | L
In other words...
换句话说...
Is there a painless way to accomplish this? Here is some psedo code of what I'd like to achieve (though I'm aware that this doesn't work):
有没有一种无痛的方法来实现这一点？这是我想要实现的一些 psedo 代码（尽管我知道这不起作用）：
SELECT pd.*, sp.* FROM Products_Detail pd
LEFT JOIN uspGetProductCategories sp ON pd.product_id = sp.product_id
Again, I know you can't do this, but hopefully it describes the logic I'm looking for.
同样，我知道你不能这样做，但希望它描述了我正在寻找的逻辑。
Example Desired Output
所需输出示例
products_id | manufacturer | purchaser | pay_type | products_model | Leather Seats | Heated Seats | Tapedeck | Heater | Hybrid | Sunroof | Cruise Control
=========================================================================================================================================================
100 | GM | GREG | P | Saturn Vue | N | N | Y | N | N | N | N
200 | TOYT | SAM | P | Toyota Pruis | Y | N | N | Y | Y | N | N
300 | FORD | GREG | L | Ford Focus | N | N | N | Y | N | N | Y

If you cannot create a temp table with the data from the dynamic stored procedure, why not just join on the table directly:
如果您无法使用动态存储过程中的数据创建临时表，为什么不直接加入该表：
DECLARE @cols AS NVARCHAR(MAX),
@colsNull AS NVARCHAR(MAX),
@query AS NVARCHAR(MAX)
select @cols = STUFF((SELECT distinct ',' + QUOTENAME(categories_name)
from Categories
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
select @colsNull = STUFF((SELECT ',IsNull(' + QUOTENAME(categories_name)+', ''N'')'+' as '+QUOTENAME(categories_name)
from Categories
group by categories_name, categories_id
order by categories_id
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set @query = '
select *
from Products_Detail pd
left join
(
SELECT products_id,
products_model,' + @colsNull + ' from
(
select p.products_id,
p.products_model,
c.categories_name,
''Y'' flag
from products p
left join Products_Categories pc
on p.products_id = pc.products_id
left join Categories c
on pc.categories_id = c.categories_id
) x
pivot
(
max(flag)
for categories_name in (' + @cols + ')
) p
) p
on pd.products_id = p.products_id'
execute(@query)

Try using this ugly solution if no way to reorganize your code.
如果无法重新组织代码，请尝试使用这个丑陋的解决方案。
SELECT * INTO #tmp
FROM OPENROWSET('SQLNCLI', 'server=INSTANCENAME;database=DBNAME;trusted_connection=yes', 'uspGetProductCategories') A
You must have allowed Ad Hoc Distributed Queriesin your server.

You can do this:
你可以这样做：
INSERT aTemptable
EXEC yourstoredproc
if #t has been defined but you cannot do select into #t and have it be created dynamically.
如果#t 已定义，但您不能选择#t 并动态创建它。
