我有两个表，一个是桌面，另一个是桌面主要

桌面桌

    ID int IDENTITY(1,1) PRIMARY KEY, 
    Company varchar(35), 
    Model_A varchar(50), 
    Model_B varchar(50), 
    Dealer varchar(35),

    System_Serial varchar(50), 
    Processor varchar(50), 
    Processor_Generation varchar(50), 
    Processor_speed varchar(30), 
    RAM varchar(30), 
    Hard_Disk varchar(30), 
    OS varchar(50), 
    OS_Bit varchar(15), 
    OS_Key varchar(40), 
    UserName varchar(50),

    Remarks varchar(100), 
    EntredBy varchar(30), 
    EntryDate varchar(15), 
    UpdatedBy varchar(30),
    UpdatedDate varchar(15)
)

DeksktopMain表

create table DesktopMain (
    Service_ID int IDENTITY(1,1) PRIMARY KEY, 
    ID int FOREIGN KEY REFERENCES Desktop (ID),
    Request_Date varchar(15), 
    Call_loggedby varchar(20), 
    Service_No varchar(30), 
    Order_No varchar(30),
    Days_Pending int, 
    End_Date varchar(15), 
    Working_Status varchar(3), 
    Service_Centre varchar(30), 
    Engineer_Name varchar(40), 
    Mobile_No varchar(25), 
    KeyBoard_Old_FRU varchar(20), 
    KeyBoard_Old_Sir varchar(20), 
    KeyBoard_New_FRU varchar(20), 
    KeyBoard_New_Sir varchar(20), 
    Mouse_Old_FRU varchar(20), 
    Mouse_Old_Sir varchar(20), 
    Mouse_New_FRU varchar(20), 
    Mouse_New_Sir varchar(20), 
    Problem_Detail varchar(400), 
    Part_Installed varchar(50), 
    Part_Serial varchar(50), 
    Report_Detail varchar(200)
)

我在Desktop Main中有Foreign key ID。我想在桌面表格中显示1行，并与该桌面ID相关，该桌面ID与该1行下的桌面主要节目中的foreign key匹配。像钻取下来
