delphi導出數據至Excel的三種方法及比較閒來無事，跑到網上搜集了幾種導出DataSet至Excel的幾種方法。另外使用GetTickcount函數計算時差，以便比較。（原本使用Timer控件，可是Timer不適合作高精度時間計算）使用TADOConnect，TADOQuery查詢數據。方法五： 使用TADOQuery + Varaint方法，循環遍歷數據集中數據，直接插入到Excel的WookBook單元。這是初學者最易懂和易接受的方法。在下面代碼中沒有仔細注意語法（好比沒有使用try..finally結構體），若是須要使用，請注意：//使用ADO循環方式保存。.net
procedure TForm1.btn_WhileClick(Sender: TObject);
var
Eclapp:variant;
n:integer;
filename: string;
t1,t2: Int64;
begin
Eclapp := CreateOleObject('Excel.Application');
Eclapp.WorkBooks.Add;
Eclapp.Visible:= False;
filename :='d:\數據1.xls';
lbl2.Caption := '0';
if FileExists(fileName) then
DeleteFile(fileName);
t1:= GetTickCount;
qry1.DisableControls;
qry1.First;
n:=2;
while not qry1.Eof do
begin
eclapp.cells[n,1] := qry1.Fields[0].AsString;
eclapp.cells[n,2] := qry1.Fields[1].AsString;
eclapp.cells[n,3] := qry1.Fields[2].AsString;
eclapp.cells[n,4] := qry1.Fields[3].AsString;
//爲了簡單，只添加了4個欄位 inc(n);
qry1.Next;
application.ProcessMessages;
end;
qry1.EnableControls;
t2:= GetTickCount;
eclapp.visible := false;
eclapp.Workbooks[1].SaveAs(filename);
Eclapp.Quit;
Eclapp:= Unassigned;
lbl2.Caption := IntToStr(t2 - t1);
end;
方法六：使用OLE方法導入。 先講TDateSet中的數據保存爲二維OLEVariant數組中，再保存到Excel Sheet中 ///使用OLE方式保存。excel
procedure
TForm1.btn_OleVariantClick(Sender: TObject);
var
fileName: string;
xlApp, Sheet: OleVariant;
rowCount, Colcount, index: Integer;
t1,t2: Int64;
function RefToCell(RowID, ColID: Integer): string;
var
ACount, APos: Integer;
begin
ACount := ColID div 26;
APos := ColID mod 26;
if APos = 0 then
begin
ACount := ACount - 1;
APos := 26;
end;
if ACount = 0 then
Result := Chr(Ord('A') + ColID - 1) + IntToStr(RowID);
if ACount = 1 then
Result := 'A' + Chr(Ord('A') + APos - 1) + IntToStr(RowID);
if ACount > 1 then
Result := Chr(Ord('A') + ACount - 1) + Chr(Ord('A') + APos - 1) + IntToStr(RowID);
end;
function getData(ds: TDataSet): OleVariant;
var
Data: OLEVariant;
i,j : Integer;
begin
rowCount := ds.RecordCount;
colCount := ds.FieldCount;
Data := VarArrayCreate([1, rowCount + 1, 1, colCount], varVariant); //1，rowCount
表示第一維數組的上下標，1，colCount表示第二維數組的上下標 i := 1;
for j := 0 to colCount - 1 do
begin
if not ds.Fields[j].Visible then
continue;
Data[i,j + 1] := ds.Fields[j].DisplayLabel;
end;
Inc(i);
ds.DisableControls;
try
ds.First;
while not ds.Eof do
begin
for j := 0 to colCount - 1 do
begin
Data[i,j + 1] := ds.Fields[j].AsString;
end;
Inc(i);
ds.Next;
Application.ProcessMessages;
end;
finally
ds.EnableControls;
end;
result := Data;
end;
begin
fileName := 'd:\數據.xls';
lbl1.Caption := '0';
t1:= GetTickCount;//開始計時if FileExists(fileName) then
DeleteFile(fileName);
xlApp := CreateOleObject('Excel.Application');
try
XLApp.Visible := False;
XLApp.DisplayAlerts := False;
XLApp.Workbooks.Add;
// 刪除多餘的 worksheet
for index := XLApp.SheetsInNewWorkbook downto 2 do
begin
XLApp.Workbooks[1].Worksheets[index].Delete;
end;
Sheet := XLApp.Workbooks[1].Worksheets[1];
index := 1;
if index <> 0 then
Sheet := XLApp.Workbooks[1].Worksheets.Add;
Sheet.Name := qry1.Name;
//Sheet.Columns.NumberFormatLocal := '@'; //設置單元格式爲文本 Sheet.Range[RefToCell(1, 1), RefToCell(rowCount + 1, colCount)].Value := getData(qry1);
XLApp.Workbooks[1].SaveAs(fileName);
finally
if not VarIsEmpty(XLApp) then
begin
XLApp.Quit;
XLAPP := Unassigned;
Sheet := Unassigned;
application.ProcessMessages;
t2:= GetTickCount;
lbl1.Caption := IntToStr( t2 - t1);
end;
end;
end;
