使用ASP from SQL从具有相同id的相同列名的多个表中得到的结果

我需要一些帮助编写ASP从SQL获取数据

我有三张桌子——电脑、显示器和监视器2。Monitor2表是Monitor表（包括数据）的精确克隆。（别问我为什么，在我来这里之前就做了）

从PC表中使用的列 PC_ID、名称（加上一些其他名称，但此处不相关）

监视器和监视器2表中的列 监视器ID、名称、尺寸、PC ID、品牌、型号

基本上，我需要提取结果来填充一个表，该表显示了哪个PC.Name具有哪个Monitor.Name、Monitor2.Name和其他属性

例如

这就是我目前所拥有的

sqlq = "SELECT PC.PC_ID, PC.PC_Name, PC.CPU, PC.RAM, PC.Make, PC.Model, PC.Date, Monitor2.Name as mon_name2, Monitor2.Size as mon_size2, Monitor.Name as mon_name, Monitor.Size as mon_size FROM Monitor right JOIN PC ON Monitor.PC_ID = PC.PC_ID FROM Monitor2 right JOIN PC ON Monitor2.PC_ID = PC.PC_ID
set rs = conn.execute(sqlq)
if rs.eof or rs.bof then
response.write("No Records Found")
else
'count how many records have been returned
count=0
rs.movefirst
pcname=""
do while not rs.eof
if pcname <> rs("PC_Name") then
count=count+1
end if
pcname=rs("PC_Name")
rs.movenext
loop

Response.write("<font size='2'>No. of records returned:" & count & " </font>")
rs.movefirst
pcname=""
%>
<%if not PrintF then %>

如果不是那样的话，我会得到 无法绑定多部分标识符“Monitor2.Name” 或者其他一些不正确的语法错误

为您的帮助干杯

FROM Monitor right JOIN PC ON Monitor.PC_ID=PC.PC_ID FROM Monitor2

从中取出第二个

。。这是监视器2中的

这就给你留下了

SELECT  PC.PC_ID,
        PC.PC_Name,
        PC.CPU,
        PC.RAM,
        PC.Make,
        PC.Model,
        PC.Date,
        Monitor2.Name AS mon_name2,
        Monitor2.Size AS mon_size2,
        Monitor.Name AS mon_name,
        Monitor.Size AS mon_size
FROM    Monitor
        RIGHT JOIN PC ON Monitor.PC_ID = PC.PC_ID
        RIGHT JOIN PC ON Monitor2.PC_ID = PC.PC_ID

这是没有道理的，也是不正确的。我想你是想做这样的事

SELECT  PC.PC_ID,
        PC.PC_Name,
        PC.CPU,
        PC.RAM,
        PC.Make,
        PC.Model,
        PC.Date,
        Monitor2.Name AS mon_name2,
        Monitor2.Size AS mon_size2,
        Monitor.Name AS mon_name,
        Monitor.Size AS mon_size
FROM    PC
        LEFT JOIN Monitor ON Monitor.PC_ID = PC.PC_ID
        LEFT JOIN Monitor2 ON Monitor2.PC_ID = PC.PC_ID

如果你在监视器或监视器2中有一台电脑ID的多条记录，你会被复制。
JamieD77因为你真的很有帮助，你能看看我刚才提出的其他问题吗？需要重新审视一下。Thx-
