好吧,我正在做我的作业,我很难弄清楚如何与SQL相乘以及如何正确地进行订购.

我应该"创建一个查询列出玩家(player_name),当前工资和新(创建)列的查询,该列反映工资增加10%(按工资*1.1计算).按工资按降序排序数据."

它只是一个简单的NHL数据库,我们的老师为这项任务做了准备.球员表中有74名球员.选手表中的字段是:player_id,player_name,player_salary,team_id和position_id.

这是我到目前为止:

SELECT player_name, player_salary, SUM(player_salary*1.1) AS NewSalary
FROM players
GROUP BY player_salary, player_name;

这样它至少可以运行.我相信我必须将GROUP BY更改为ORDER BY并在最后使用DESC标记,但这不起作用.这是我从运行此查询得到的输出:

PLAYER_NAME          PLAYER_SALARY          NEWSALARY

我试图弄清楚如何保留此页面上控件的值(只是用户提交的佣金值和销售区域(东部是10%,西部是20%)).

代码如下:

<form id='frmShowCommSingleDocKeepState' action='afShowCommSingleDocKeepState.aspx' method='get' >
<div>

              <%  
                Dim strSale As String
                Dim dblSale As Double
                Dim strRegion As String
                  Dim dblComm As Double
                  Dim E As Double = 0.1
                  Dim W As Double = 0.2

                  strSale = Request.QueryString("txtSale")
                  If strSale = "" Then
                      Response.Write("Monthly Sale")
                      Response.Write("<input id='txtSale' type='text' name='txtSale'/><br /><br />")
                      Response.Write("Select your Sales Region: ")
                      Response.Write("<select id='lstRegion' name='lstRegion' size='2'>")
                      Response.Write("<option value='E'> Eastern</option>")
                      Response.Write("<option value='W'> Western</option>")
                      Response.Write("</select><br /><br />")
                      Response.Write("<input id='btnShowCommission' type='submit' value='Show Commission' /><hr /><br />")

                  Else …
