自动生成流水号的问题
流水号有这些元素：楼，房间，架子，行，列
假设现在有20栋楼，每栋楼有30个房间，每个房间有15个架子，每个架子有10行，20列
怎么样写个循环来自动自动生成上面的流水号从第一个：0101010101到最后一个2030151020

SQL code

if object_id('tempdb.dbo.#') is not null drop table #create table #(    i int identity(0,1),    id as right('0'+ltrim(i/90000+1),2)+right('0'+ltrim(i/3000%30+1),2)+right('0'+ltrim(i/200%15+1),2)+right('0'+ltrim(i/20%10+1),2)+right('0'+ltrim(i%20+1),2),    data varchar(1))insert # select 'a'insert # select 'b'select * from #/*i           id                   data----------- -------------------- ----0           0101010101           a1           0101010102           b*/
