此SQL是对标模块的临时表查询，他能查出一个指标下面的多个子指标的公式，并分层级显示 @指标ID=#*1*#;#*1*#08bea0aaf-0ed2-4c9b-8c20-8c5bd919db6f#*1*#
摘自EOTS 存储过程up_eots_Get_QuotaStruct
临时表循环的关键就是下面的语句, select top 1 from #Tep,用一个变量循环取值，然后删除循环中的值
复制代码 代码如下:
insert into #Tep select optname,value,major_version from MSreplication_options
while Exists(select a from #Tep)
begin
select top 1 @tempa =a,@tempc =c from #Tep
delete #Tep where a=@tempa
end
