在存儲過程中使用動態sql

declare @sql nvarchar(4000)

if @sortName = ''
set @sortName= 'CommodityTypeId'
if @sortType = ''
set @sortType = 'Asc'

set @sql='
select *,Alltypename=dbo.f_fullname(commoditytypeid) from t_INSMCommodityType
where enable=1
order by '+@sortName+ '  ' +@sortType + '
'

exec SP_EXECUTESQL @sql
GO
