还是上次SQL语句，有些bug，不会修改了，坐等啊！！！这破脑子。。

连建表带查询的语句如下：

CREATE TABLE #a(P_Code nvarchar(20))
INSERT #a  SELECT 'A01'
UNION ALL SELECT 'A02'
UNION ALL SELECT 'B01'
UNION ALL SELECT 'B02'

CREATE TABLE #b(Con_Code nvarchar(20),Con_Name nvarchar(20))
INSERT #b  SELECT 'W01','一号柜'
UNION ALL SELECT 'W02','二号柜'
UNION ALL SELECT 'W03','三号柜'

CREATE TABLE #c(Con_Code nvarchar(20),P_Code nvarchar(20),P_Num int)
INSERT #c  SELECT 'W01','A01',10
UNION ALL SELECT 'W01','A02',20
UNION ALL SELECT 'W02','B01',30
UNION ALL SELECT 'W03','B02',40
UNION ALL SELECT 'W03','A01',100

DECLARE @case nvarchar(2000)
DECLARE @sql nvarchar(4000)
SELECT @case=ISNULL(@case,'')+'CASE Con_Name WHEN '''+Con_Name+''' THEN P_Num ELSE 0 END ['+Con_Name+'],' FROM #b ORDER BY Con_Code
PRINT @case
SET @case=SUBSTRING(@case,1,LEN(@case)-1)
SET @sql='SELECT P_Code,'+@case+' FROM (SELECT a.P_Code,c.P_Num,Con_Name FROM #c c INNER JOIN #a a ON c.P_Code=a.P_Code INNER JOIN #b b ON c.Con_Code=b.Con_Code)t'
EXEC(@sql)

现在这样的查询结果为：
P_Code 一号柜 二号柜 三号柜
A01 10 0 0
A02 20 0 0
B01 0 30 0
B02 0 0 40
A01 0 0 100

我想得到结果如下：

P_Code 一号柜 二号柜 三号柜
A01 10 0 100
A02 20 0 0
B01 0 30 0
B02 0 0 40

试试这个

declare @sql nvarchar(4000)
set @sql='Select P_Code '
Select @sql=@sql+',sum(case when Con_Code='''+Con_Code+ ''' then P_Num else 0 end) As '''+Con_Code+''''
From #c Group By Con_Code
Print @sql
set @sql=@sql+' From #c Group By P_Code'
Print @sql
execute sp_executesql @sql

--在case上加上sum,最后聚合一下就行了
DECLARE @case nvarchar(2000)
DECLARE @sql nvarchar(4000)
SELECT @case=ISNULL(@case,'')+'SUM(CASE Con_Name WHEN '''+Con_Name+''' THEN P_Num ELSE 0 END) ['+Con_Name+'],' FROM #b ORDER BY Con_Code
SET @case=SUBSTRING(@case,1,LEN(@case)-1)
SET @sql='SELECT P_Code,'+@case+' FROM (SELECT a.P_Code,c.P_Num,Con_Name FROM #c c INNER JOIN #a a ON c.P_Code=a.P_Code INNER JOIN #b b ON c.Con_Code=b.Con_Code)t GROUP BY P_Code'
EXEC(@sql)
/*
P_Code               一号柜         二号柜         三号柜
-------------------- ----------- ----------- -----------
A01                  10          0           100
A02                  20          0           0
B01                  0           30          0
B02                  0           0           40

楼主离成功只差一步。
在你之前的基础之上，只要再建个临时表，把上面的结果插入进去，然后再select出来，group by p_code就可以了，很好的。

[xuan.ye]

改进一下：
declare @sql nvarchar(4000)
set @sql='Select P_Code '
Select @sql=@sql+',sum(case when Con_Code='''+#b.Con_Code+ ''' then P_Num else 0 end) As '''+Con_Name+''''
From #c INNER JOIN #B on #c.Con_Code=#b.Con_Code Group By #b.Con_Code,#b.Con_Name
Print @sql
set @sql=@sql+' From #c Group By P_Code'
Print @sql
execute sp_executesql @sql

求解释 sql建立临时表改怎么保存?

自动保存到SQLSERVER里面，具体的位置没去了解过。生命周期是依赖于连接。连接结束，临时表的生命周期结束。
