初学

用的什么数据库,控件?

我用的是临时表方法
1:在server中创建一个存储过程
CREATE proc CopyTable
    @cnt int,
    @custom_type_num varchar(2),
    @custom_type_name varchar(10)    
As
declare @cnt1 int
    if not exists(select * from dbo.sysobjects where id=object_id(N'[dbo].[temp_custom_type]')
        and objectproperty(id,N'IsUserTable')=1)
    begin
        select * into temp_custom_type from custom_type where 0=1
    end
    select @cnt1=count(*)
    from  temp_custom_type 
    where custom_type_num=@custom_type_num

    if @cnt>0
    begin
        if @cnt1<=0
        begin
            insert into temp_custom_type(custom_type_num,custom_type_name) values(@custom_type_num,@custom_type_name)
        end
    end
    if @cnt=1
    begin
        select * from temp_custom_type
    end

GO
2:再创建一个清空临时表的存储过程
CREATE proc ClearTable
    
As
    if not exists(select * from dbo.sysobjects where id=object_id(N'[dbo].[temp_custom_type]')
        and objectproperty(id,N'IsUserTable')=1)
    begin
        select * into temp_custom_type from custom_type where 0=1
    end
    delete temp_custom_type

GO
3:在delphi下,一个DBGrid,一个Button,一个ADOStoredProc name为SP1,两个AdoQuery和DataSource
Button的OnCilck事件
var i,cnt:integer;
    BookMark : TBookMark;
//iLoop,i: Integer;
//sBH: string;
begin
       AdoQuery2.Close;
       with sp1 do
       begin
                close;
                ProcedureName:='ClearTable;1';
                parameters.Refresh;
                ExecProc;
       end;    // with
        BookMark:=AdOQuery1.GetBookmark;
        cnt:=DBGrid1.SelectedRows.Count;
        for i := 0 to DBGrid1.SelectedRows.Count - 1 do    // Iterate
        begin
               adoQuery1.GotoBookmark(pointer(DBGrid1.SelectedRows.Items[i]));
               with sp1 do
               begin
                        close;
                        ProcedureName:='CopyTable;1';
                        parameters.Refresh;
                        parameters.ParamByName('@cnt').Value:=cnt;
                        parameters.ParamByName('@custom_type_num').Value:=AdOQuery1.fieldByName('custom_type_num').Value;
                        parameters.ParamByName('@custom_type_name').Value:=AdOQuery1.fieldByName('custom_type_name').Value;
                        ExecProc;
               end;    // with
               cnt:=cnt-1;
        end;    // for
        AdOQuery1.FreeBookmark(BookMark);
        //AdoQuery2.Open;
        sp1.Open;
        //下面是打印    
        DBGrid2.DataSource:=DSSP1;
        Application.CreateForm(TForm2, Form2);
        form2.RMRePort1.LoadFromFile('E:\ljp\多行打印\Untitled.rmf');
        form2.RMReport1.ShowReport; 
end;
