这是两个表,我被困在这两个表之间的查询中。 我需要列出卖家名称和他们销售的不同类型智能手机的数量。此外,结果应按电话类型数的后代顺序排序。 在一栏中我需要卖家名称而另一栏我需要卖家出售的电话总数。
像lisa mcdonals一样卖3种不同类型的手机。答案 0 :(得分:2)
试试这个:
select S.sellerName, P.productID from seller S join product P on S.SellerID=P.SellerID order by P.productID;
答案 1 :(得分:1)
如果您将表名调整为自己的名称,这将有效:
SELECT Seller.SellerName,
Product.ProductID
FROM Seller
LEFT JOIN Product
ON Product.SellerID = Seller.SellerID
ORDER BY ProductID DESC

您必须加入这两个表并按@model ConflictOfInterest.Models.ReportParamters
@{
if (Model.SelectedTab != "0")
{
<table border="0" cellpadding="0" cellspacing="0">
@{
if (Model.SelectedTab == "1")
{
<tr>
<td style="font-weight:bolder">@Html.Label("Year", "Year:")</td>
<td>@Html.DropDownListFor(model => model.Year, Enumerable.Empty<SelectListItem>(), (DateTime.Today.Year - 1).ToString(), new { @style = "width:200px;" })
</td>
<td style="font-weight:bolder">@Html.Label("ReportType", "Report Type:")</td>
<td>@Html.DropDownListFor(model => model.ReportType, new SelectList(ViewBag.ReportType, "value", "Text"), new { @style = "width:200px;" })</td>
<td style="font-weight:bolder">
@Html.Label("Person", "Person:")
@Html.Label("Group", "Group:")
</td>
<td>
@Html.DropDownListFor(model => model.Group, new SelectList(ViewBag.GroupList, "value", "Text"), new { @style = "width:200px;" })
@Html.DropDownListFor(model => model.Person, Enumerable.Empty<SelectListItem>(), "All", new { @style = "width:200px;" })<br />
@Html.TextBox("sPerson")
<input type="button" id="bPerson" value="Search" />
</td>
</tr>
}
/*else
{
<tr>
<td colspan="6"></td>
</tr>
}*/
}
<tr>
<td style="font-weight:bolder">@Html.Label("Division", "Division:")</td>
<td>@Html.DropDownListFor(model => model.Division, new SelectList(ViewBag.Division, "value", "Text"), new { @style = "width:200px;" })</td>
<td style="font-weight:bolder">@Html.Label("Department", "Department:")</td>
<td>@Html.DropDownListFor(model => model.Department, Enumerable.Empty<SelectListItem>(), "All", new { @style = "width:200px;" })</td>
<td style="font-weight:bolder">@Html.Label("Section", "Section:")</td>
<td>@Html.DropDownListFor(model => model.Section, Enumerable.Empty<SelectListItem>(), "All", new { @style = "width:200px;" })</td>
</tr>
<tr>
<td colspan="6"></td>
</tr>
</table>
}
else
{
<table border="0" cellpadding="0" cellspacing="0">
<tr>
<td>Show the detail captered by direct reports.</td>
</tr>
</table>
}
}
对结果进行分组,以便计算每个卖家销售的手机数量。
SellerName
请注意,这些可能不是您的表名,因为您没有提供它们。
