SQL服務器對動態表，2005年樞軸插入到表

Question

我有一個創建一個動態表，以填補網格在SSRS報告同時創建假的列和假行的查詢。

Declare @FieldLogID as int 
Set @FieldLogID = 1018; 

With EmployeeActivity as 
(
SELECT distinct *, row_number() over(order by Employee_EmployeeID)as row 
from 
    (

Select Employee_EmployeeID, 
Employee_FullName, 
Injured_Today_Custom, 
--Case when JobAccount_TrackingID like'zzz%' then Null else JobAccount_TrackingID end as 
JobAccount_TrackingID, 
StartDateTime, 
StopDateTime, 
WorkHours 
from 
(
Select row_number() over (partition by Employee_EmployeeID order by JobAccount_TrackingID) row,* 
from 
(
SELECT DISTINCT 
CustomizedFieldLogEmployee_1.Employee_EmployeeID, 
CustomizedFieldLogEmployee_1.Employee_FullName, 
NULL as Injured_Today_Custom, 
CustomizedFieldLogJobAccount_1.JobAccount_TrackingID, 
null as StartDateTime, 
null as StopDateTime, 
null as WorkHours 
FROM 
CustomizedAccount INNER JOIN CustomizedFieldLogJobAccount AS CustomizedFieldLogJobAccount_1 ON CustomizedAccount.AccountID = CustomizedFieldLogJobAccount_1.Account_AccountID 
RIGHT OUTER JOIN CustomizedFieldLogEmployee AS CustomizedFieldLogEmployee_1 ON CustomizedFieldLogJobAccount_1.FieldLog_FieldLogID = CustomizedFieldLogEmployee_1.FieldLog_FieldLogID 
WHERE   
CustomizedFieldLogEmployee_1.FieldLog_FieldLogID = @FieldLogID 
AND 
CustomizedAccount.AppliesToEmployees = 1 
Union 
(Select 'aaaa01' EmployeeID,NULL,NULL,NULL,NULL,NULL,NULL 
     union Select 'aaaa02',NULL,NULL,NULL,NULL,NULL,NULL 
     union Select 'aaaa03',NULL,NULL,NULL,NULL,NULL,NULL 
     union Select 'aaaa04',NULL,NULL,NULL,NULL,NULL,NULL 
     union Select 'aaaa05',NULL,NULL,NULL,NULL,NULL,NULL) 
Union 
Select Distinct 
Employee_EmployeeID, 
Employee_FullName, 
null as Injured_Today_Custom, 
fake_TrackingID, 
null as StartDateTime, 
null as StopDateTime, 
null as WorkHours 
FROM 
CustomizedFieldLogEmployee 
cross join 
(
Select 'zzz01' fake_TrackingID 
union Select 'zzz02' 
union Select 'zzz03' 
union Select 'zzz04' 
union Select 'zzz05' 
union Select 'zzz06' 
union Select 'zzz07' 
union Select 'zzz08' 
union Select 'zzz09' 
union Select 'zzz10' 
) a where FieldLog_FieldLogID = @FieldLogID 
) b 
) c where Row<=9 
--order by Employee_EmployeeID,JobAccount_TrackingID 
)d 
); 

Select * from EmployeeActivity 

我現在需要將它轉換爲表格。我使用下面的函數做一個動態支點試過了，但是當我試圖運行它，我得到一個錯誤說

Incorrect Syntax near the Keyword Exec.

代碼：

create procedure dynamic_pivot 
(
@select varchar(2000), 
@PivotCol varchar(100), 
@Summaries varchar(100) 
) as 
declare @pivot varchar(max), @sql varchar(max) 
select @select =replace(@select,'select ','select '+@PivotCol+' as pivot_col,') 


create table #pivot_columns (pivot_column varchar(100)) 

Select @sql='select distinct pivot_col from ('+@select+') as t' 

insert into #pivot_columns 
exec(@sql) 

select @pivot=coalesce(@pivot+',','')+'['+pivot_column+']'from #pivot_columns 

select @sql= 
' 
    select * from 
    (
     '+@select+' 
    ) as t 
    pivot 
    (
     '+@Summaries+' for pivot_col in ('+@pivot+') 
    ) as p 
' 

exec(@sql) 

SQL的執行導致錯誤：

EXEC dynamic_pivot 
    'SELECT Employee_EmployeeID, Employee_FullName,StartDateTime from EmployeeActivity', 
    'JobAccount_TrackingID', 
    'Count(row)' 

現在我沒有綁定到這個函數來轉移這些數據，但是有一件事阻止我做標準的pivot，那就是我不會知道直到運行時組成列的值。

什麼是這樣做的最佳方式？

Answer 1

您的動態數據透視表正在處理實際表格，而不是COMMON TABLE EXPRESSION（您使用關鍵字WITH定義的表格）。一個簡單的解決方案是從CTE中創建一個真正的表格。

在頂部添加

if object_id('tempdb..#EmployeeActivity') is not null 
drop table #EmployeeActivity; 

在查詢的結尾添加into #EmployeeActivity條款：

Select * 
into #EmployeeActivity 
from EmployeeActivity; 

您的動態支點應該工作。注意：我認爲row需要在選擇列表中。

EXEC dynamic_pivot 
'SELECT Employee_EmployeeID, Employee_FullName,StartDateTime,row from EmployeeActivity', 
'JobAccount_TrackingID', 
'Count(row)'
