Question

我尝试了以下所有链接，但是它们在我的Sever SQL中不起作用吗？

SET @cols = STUFF((SELECT ',' + QUOTENAME(AD.MonthFormat) FROM #tempMonthFormat AD FOR xml PATH (''), TYPE).value('.', 'nvarchar(max)'), 1, 1, '')
  SELECT @Selectcols =  STUFF((SELECT 
    ',' + ISNULL(@Selectcols + ',','')+ 'ISNULL(' + QUOTENAME(AD.MonthFormat) + ', 0) AS ' + QUOTENAME(AD.MonthFormat)  FROM #tempMonthFormat AD 
  FOR xml PATH (''), TYPE)
  .value('.', 'nvarchar(max)'), 1, 1, '');

Declare @FINALQUERY varchar(max);    
SET @FINALQUERY = '         
                      SELECT  Name,[Issue],' + @Selectcols + ' FROM
                     (
                         SELECT   into #temptable * FROM #Meantimeresult  
                     ) Y
                     PIVOT 
                     (
                         SUM(MT)
                         FOR [Monthformat] IN (' + @cols + ')               
                    ) p GROUP BY ' + @cols+',[Issue], Name'                

        EXEC SP_EXECUTESQL @FINALQUERY;

Dynamic SQL Result INTO #Temp Table

How to create temp table from a dynamic query?

INSERT INTO temp table from unknown number and name of columns (from dynamic PIVOT query) Dynamic Pivot Results to a Temp Table

Answer 1

可以通过几个步骤来完成，但是此答案的复杂特性应向您表明您在此处与sql server作战，而不是与之作战。尽力寻找另一种方式来组织报告，以免在采取此类严厉措施之前不需要这样做。

1）封装/修改您的初始数据透视查询为无参数存储过程。如果您需要将任何数据传递到过程中，则必须将其构造为 global 临时表（以##为前缀的临时表），例如

CREATE PROCEDURE dynamic_meantime_pivot AS
DECLARE 
    @cols nvarchar(max) = STUFF(
        (SELECT ',' + QUOTENAME(AD.MonthFormat) FROM ##tempMonthFormat AD FOR xml PATH (''), TYPE)
        .value('.', 'nvarchar(max)'), 1, 1, '')
    @Selectcols nvarchar(max) = STUFF(
        (SELECT ',' + ISNULL(@Selectcols + ',','')+ 'ISNULL(' + QUOTENAME(AD.MonthFormat) + ', 0) AS ' + QUOTENAME(AD.MonthFormat)  FROM ##tempMonthFormat AD FOR xml PATH (''), TYPE)
        .value('.', 'nvarchar(max)'), 1, 1, '');

Declare @FINALQUERY varchar(max) = '         
                      SELECT  Name,[Issue],' + @Selectcols + ' FROM
                     (
                         SELECT * FROM ##Meantimeresult  
                     ) Y
                     PIVOT 
                     (
                         SUM(MT)
                         FOR [Monthformat] IN (' + @cols + ')               
                    ) p GROUP BY ' + @cols+',[Issue], Name'                

EXEC(@FINALQUERY)

2）设置上述过程所需的任何全局临时表。

3）通过OPENROWSET函数调用该过程，如下所示：

SELECT * INTO #dynamic_meantime_table FROM OPENROWSET('SQLNCLI', 'Server=<your_sql_server_instance_name_here>;Trusted_Connection=yes;',
     'EXEC dynamic_meantime_pivot')
