declare @sql varchar(8000)
set @sql = 'select makedate,'
select @sql = @sql + 'sum(case status when '''+status+'''
then status else 0 end) as '''+status+''','
from (select distinct status from e3_m_process) as a
select @sql = left(@sql,len(@sql)-1) + ' from e3_m_process group by makedate'
print @sql
標準語法。
declare @sql varchar(8000)
set @sql = 'select name,'
select @sql = @sql + 'sum(case subject when '+''''+subject+''''+'
then source else 0 end) as '+''''+subject+''''+','
from (select distinct subject from test) as a
select @sql = left(@sql,len(@sql)-1) + ' from test group by name'
exec(@sql)
標準執行。
內部子查詢裡面查詢的必須是數值型的，因為外層用的是sum
declare @sql varchar(8000)
set @sql = 'select style_id,'
select @sql = @sql + 'sum(case status when '''+status+'''
then status else 0 end) as '''+status+''','
from (select distinct status from m2c_mrpd_style where not status is null) as a
select @sql = left(@sql,len(@sql)-1) + ' from m2c_mrpd_style group by style_id'
print @sql
語句的進一步完善。假如為空，會出現沒語句輸出的情況。

SQL動態交叉表
動態交叉表就是列表可以根據表中資料的情況動態建立列。動態查詢不能使用 select 語句實現，它可以利用儲存過程實現。思路是 首先檢索列頭資訊，形成乙個游標，然後遍歷游標，將上面靜態交叉表實現過程中使用 case 語句判斷的內容用游標裡的值替代，形成一條新的 sql查詢語句，然後執行並返回結果。下面...
