怎么样去合并数据??
create table #tt
(
fid nvarchar(30),
fname nvarchar(30),
fbh nvarchar(30),
frq datetime
)
insert into #tt
select 'A1013','AG-14339','制模','2012-10-09'
union all
select 'A1013','AG-14339','修边','2012-10-11'
union all
select 'A1013','AG-14339','小红','2012-10-12'
declare @sql nvarchar(4000)
set @sql = ' select distinct fid,fname,'
select @sql=@sql+' (case fbh when '''+fbh+''' then convert(varchar(10),frq,121) else null end ) as '''+fbh+''','
from (select fbh from #tt ) a
select @sql=left(@sql,len(@sql)-1) +' from #tt '
exec (@sql)
怎么使数据并为一行

- SQL code
declare @sql nvarchar(4000)
set @sql = ' select fid,fname,'
select @sql=@sql+'MAX (case fbh when '''+fbh+''' then convert(varchar(10),frq,121) else null end ) as '''+fbh+''','
from (select fbh from #tt ) a
select @sql=left(@sql,len(@sql)-1) +' from #tt GROUP BY fid,fname'
exec (@sql)
/**
fid fname 制模 修边 小红
------------------------------ ------------------------------ ---------- ---------- ----------
A1013 AG-14339 2012-10-09 2012-10-11 2012-10-12
