如果我能让问题更容易理解,请告诉我,因为我真的可以帮忙...
我们有一个包含类别和别名的目录,我正在尝试添加创建进入顶级类别的别名子类别的功能,目前我们可以只将别名子类别添加到其他子类别,这不是我们想要的。
例如,我想将子类别'地产代理'添加到主要类别'Home and Garden'和< em>'财务与抵押'。
我只能将'地产代理'添加到其中一个子类别中,因此希望在下拉选择选项中包含顶级类别以及子类别。希望有意义!
代码在下面发布,由2个单独的文件组成,用于处理数据。目前正在请求PGID - 这是父目录GID - 即顶部等级类别。
我们希望别名下拉选择选项不仅显示父类别(PGID)顶级类别下的子类别(GID),还显示PGID顶级类别本身。
E.g。 select选项包含所有级别类别,例如:
不只是:
如果我能进一步澄清,请告诉我,因为它很简单,但很难解释!
AddAlias.asp
<!--#include virtual="/Admin/FranchiseAdmin/DirectorySetup/Aliases/i_Alias.asp"-->
<%
objConn.Open strConn
%>
<input type="hidden" **name="PGID" value="<% = Request("PGID") %>"** />
<select>
<%
SQLCommand = "SELECT * FROM Directories WHERE GID='" & CleanSQLText(Request("PGID")) & "'"
rsTemp.Open SQLCommand, objConn, adOpenStatic, adLockReadOnly
if rsTemp.RecordCount <> 1 then
FailSystemEvent "AddAlias: Failed to load Existing Parent"
Else
%>
<option value="<% = rsTemp("GID") %>"><% = rsTemp("DirectoryName") %></option><%
End if
rsTemp.Close
SQLCommand = "SELECT * FROM Directories WHERE ParentDirectoryGID IS NOT NULL AND GID <> '" & CleanSQLText(Request("PGID")) & "' ORDER BY DirectoryName"
rsTemp.Open SQLCommand, objConn, adOpenStatic, adLockReadOnly
While Not rsTemp.EOF
CreateSelectOption rsTemp("GID"), rsTemp("DirectoryName"), CleanSQLText(Request("PGID"))
rsTemp.MoveNext

rsTemp.Close

</select>
<%
objConn.Close

我在上面的代码ParentDirectoryGID IS NOT NULL
中删除了以下内容,现在我现在可以看到顶级的灾难,但由于错误而无法保存
错误是从包含文件i_Alias.asp生成的,并说:发生了错误。目录GID无效
以下是包含文件代码:i_Alias.asp

我不确定我是否完全理解你的问题,但是你可以用UNION
来做到这一点。
假设您的表A包含列desc和PGID,表B包含cols desc,GID和PGID
select * from
(
select desc, GID as X from A
union all
select desc, PGID as X from B
) both_tables_unioned
order by X, desc
所以如果表A包含:
desc GID
---- ---
A 1
B 2
和B包含:
desc PGID
---- ----
AA 1
AB 1
BA 2
BB 2
你应该得到
A 1
AA 1
AB 1
B 1
BA 1
BB 1
结果

你能更多地描述表结构吗?
它看起来是一个父子关系 所以: 目录表 有主键GID, 将外键ParentDirectoryGID添加到directory.GID
示例数据:
您想要做的是填充由父母及其所有后代组成的下拉菜单(儿童的孩子怎么办?)
如果正确,您可能希望查看oracle Connect By Prior中的分层查询(但我不知道您使用的是什么数据库引擎)
