sql存储过程，根据多个条件查询，返回一个dataTable或者DataSet

ALTER Proc [dbo].[Proc_Boss_Show]
@StrIndex varchar(500),--开始条数
@EndIndex varchar(500),--结束条数
@StrWhere  varchar(max),
@zx int --执行区间  1执行 top n  2显示所有数据
as

begin
     declare  @strSqlstr varchar(500)
     
     if(@zx=1)
     begin
         set @strSqlstr=‘select  * from (select top ‘+@EndIndex
         set @strSqlstr+=‘  row_number() over(order by 提货时间 desc)
         as xx,* from View_Boss_Show  where 1=1 ‘+@StrWhere
         set @strSqlstr+=‘ ) as xx where xx>‘+@StrIndex


    end
     if(@zx=2)
    begin
       set @strSqlstr=‘select * from  View_Boss_Show  where  1=1 ‘+@StrWhere
    end

print @strSqlstr
exec(@strSqlstr)
